Demo links fixed
A few links
on our demos page pointed to a directory /pub/doom/ on the FTP archives server.  The new server doesn't have doom/ and doom2/ entries (soft links) like did, so the /pub/idgames/ real path has to be used instead. We've updated our links, apparently limited to just the demos page.  Thanks to Peter Kottenhagen and Eliut Vázquez Campos for letting us know.

The DOOM Community Archives have moved
This information has been sent
to the various news sites including Doomworld, but we'll repeat it here too.  We've changed all our links on this site to point to the new main download site instead of

The announcement:

As many of you may be aware, the master DOOM, Quake and Unreal community archives at were closed last month. See this open letter for background information: 

We have now implemented our contingency plans for a replacement master site, and are ready to re-open the archives.

Our thanks go out to Walnut Creek and Digital River for hosting the archives on since late 1994, to all those who offered assistance during the transition (in particular IHETS), and further to all of you in the community who are making this all worth doing.

3D Gamers is now hosting the Community Archives for the DOOM-, Quake-, and Unreal-engine games. Please see 

for further detail, some of which has been extracted in the information below, and for live hyperlinks to the archives.

The new master server for the archives is 

and the new primary download server is

(kindly provided by IHETS).

We strongly recommend that you use the primary download server or one of the mirrors listed at  for all downloads. The FTP addresses for the primary download site are:  (DOOM-Engine)  (Quake-Engine)  (Unreal-Engine)

The only one of the three archives that is actively maintained is idgames/, which contains user contributions for the games DOOM, DOOM II, Heretic, Hexen and Strife. It is maintained by Ty Halderman. Feel free to upload your contributions to 

Uploads may be difficult while we work to relieve the load that the master is currently under. So far only a few of the old mirrors have switched over to the new master server, but more are expected to follow once the old master archives have been removed completely.

Thanks again for your patience during the transition. Let's go play.

Some things just don't change!  
The following 2 news items from March still apply as of today :)
We've been working
all this time, and will continue to do so.  It's all Randy Heit's fault.  He keeps adding cool features to the ZDoom version 1.23 beta, and we think of ways to use them, and we go work for a while, and then another beta comes out...  Since we do require v1.23 features, we can't release any earlier than that.  

But once v1.23 is released and stable, we'll have no more excuses.  Daedalus is pretty tight right now, and it shouldn't take much to cap it off, do final testing, and release it.

So, go bother Randy (just kidding, Randy)

Download problems
The archives are down
at CDROM.COM, as has been discussed many times on the newsgroups at Doomworld and other locations.  All our download links point there, so (surprise, surprise) they don't work.  We won't be going through every page to change links unless the main archive never comes back up, at which point we'll have to aim them all at the new master archive (wherever that might end up).

 Meanwhile, though we appreciate the effort to tell us our links don't work, don't bother.  You might be able to go to one of the mirror sites by using this link and look for our themes/TeamTNT directory.  Not really sure if that list is current either, since we can't get to the main site any better than you can, but it's a starting point.

Yes, Daedalus will still get done.

Doom2000 update
A new name
Though this was decided a while ago, the last thing we wanted to do was to spend one of our infrequent web site updates just to announce a name change.  We know other teams would have, but it would have ruined our reputation as tight-lipped.  So, since there are other things to talk about, we'll announce it now.  

The project now has a real name, Daedalus: Alien Defense. Since this project is a sequel to the Icarus saga, which was named "Icarus: Alien Vanguard," it made sense to keep it in the family.  At this point, they're defending themselves rather than attacking us, too.  It all makes sense, in a strange DOOM-like way...

Getting to the end, finally
It's been a few months since our last update on progress.  We've now got almost all levels to the final testing stage, with just a couple left that are involved in some transitions and the finale.  Some things have been changing globally as new features are made available in the engine, so that's what we'd have to call enjoyable rework.

The Punch Team (a concentrated group of team members doing final tweaking) are now in charge of the rest of the work on the project, and there are some dedicated playtesters getting started as well.  That doesn't mean we're done, or that we have a release date in mind, but it's a pleasant plateau of progress.

Interestingly, some people in the community seem to think that our Hub One release back in December '99 was all there was to this project.  Hardly.  That was a mere hint of what is to come, and in fact there have been some interesting changes made to the Hub One levels as well.

New levels for The Return
The community is participating
As we had hoped, some of the authors in the community are using the resources we released in The Return.  We've been updating the Return Levels index page as they've been added, but we haven't announced anything here on the front page.  So this is your chance, if you haven't seen the recent additions, to go get some great levels.  Rick Clark just uploaded his Mars Base 1, and there are others recently added by Wim Vanrie and Samuel A. Villareal (including a 32-level set from Samuel).  They're all available in our directory on too:

Doom2000 is still alive and so are we
Most of our email lately
has been asking about why the web site hasn't been updated lately.  As we've said before, we aren't into updating the web site to mumble  little things about progress or status, because announcements do not a product make.  This is an announcement to say that we don't have anything to announce, but at least people might think we're still alive.   And we can get more work done because people won't ask about the web site.

We're still working hard and heavy on Doom2000, and it'll still be released in all its glory one of these days or weeks or...  Some of us have had some personal life priorities that came first, but for the most part we're back on track now.  Still no dates.  We don't do dates.  So don't ask about dates.

Now, back to work....

Doom2000: Hub One - link to ZDoom 1.17c
Some folks are having trouble
finding the version of ZDoom that works best with Hub One, 1.17c, for Windows.  The more recent  versions don't seem to work as well right now, and though we'll handle those incompatibilities for the full release, you might want a link to the older version for Win32 now.  The DOS version is still available on Randy's download site but it doesn't play music, and we have music, so it sucks to miss it.   

Here's the link:  Spelled out, that's

Friday 31 December 1999
Doom2000: Hub One released
See, we told you
we'd do it this year, and it's still this year here.  We're moving west as fast as we need to...

Actually, we were hoping for a total meltdown of the Internet so we wouldn't have to work so hard at the end, but so much for that.

Hub One is 7 levels, all nicely integrated as if it was a big huge level.  If you haven't played Hexen yet, it's a pretty cool way to hook a theme together.  Well, it still is, even if you have played Hexen.  That really doesn't have anything to do with it.

So, what's in Doom2000: Hub One?  7 levels (yeah, we said that already) and hundreds of new textures, new music for the levels, new sounds, a thematically associated solo play experience (Mom didn't send me to college for nuttin').

It's only for ZDoom, and you need at least version 1.17c to play it.  We actually have only designed and tested it for that version, so though later ones may work, we haven't got  enough of a clue to reassure you.

There could be a bug or three left, since we ran out of time at the end.  Still, it's better to have a preview than nothing at all, and the full release will come storming to your PC in a couple of months, with appropriate modifications to the Hub One levels.  If you're impressed at all with Hub One, you'll be simply thrilled with the full build.

For those who don't understand hyperbole and think we're egotistical to talk this way about how great Doom2000 is, get a clue and have fun.

Go Get It, as we've said before about stuff.

Doom2000 update
Making plans
is never easy, and the failure of fulfilling well-meaning promises tears at the heartstrings... 

Okay, enough maudlin prose.  We have a problem.  It's about 22 days until we have to get Doom2000 out, and quite frankly there's no way we'll get it done and done right.  This means three things:  we're being realistic,  we're going to have to shift our focus a bit, and  you'll still get something to play.  We're not mean.  Okay, we're mean, but we're going to be nice this time.

Doom2000 takes advantage of ZDoom (Hexen) hub structures, so here's the plan...  We'll release Hub One (otherwise fondly known as "Out of the Trashcan and Into the Fire") by the end of the year.  

This doesn't mean it'll take a long time to get the rest done, since most of it is in really good shape, but it will give us time to guarantee that you'll get a TeamTNT-quality product.  The final release will come fairly early next year, and will be a full release of all of Doom2000, including the Hub One "preview" release, possibly changed a bit by then.

Thanks for your patience, sorry for any inconvenience, all our operators are busy helping other surfers, come again, and have a nice day.  Oh, and no, we're still not going to show you any screenshots.  Told you we were mean.

Monday 11 October 1999
Boom GPL has been released
See the Boom pages
for details.  Also, there is some new information below under the October 10th entry.

Note that if you're a player, you won't care about this at all.  If you're a developer, it gives you certain freedoms to use Boom source in your project, per the GNU Public License.

Sunday 10 October 1999
The Return is released
The Return has changed a bit...

The original plan was to release several levels plus the resource file, as a TeamTNT release.  But between Real Life and the Doom2000 project, it's been dragging on too long.  So here's what we've done. 

We released the RETRES (Return Resources) wad, which is used with our levels and is available now for you to use in your own levels as well.  Go to the Return web page for full details and links to the files.

Individual level authors, so far from TeamTNT only, but not restricted to that, have released 4 levels.  There are many more in the hopper, and we hope to see submissions from everyone, not just TeamTNT folks.

We've got an online form you can fill out to submit your Return-based levels to us, and we'll not only index them but also put them on in our special Return directory.  The Return has become much more than a TeamTNT product--it's now a community effort that you can all participate in.

Get the resource wad and dust off the editors.  It's time to make the Doom Community live again.

Doom2000 status
We're on target 
for a year-end release, as expected.  We've done some shuffling of the hubs to make it more coherent and to help the storyline flow.  We've got nearly 500 new textures and 200 new flats done, and are still generating more.  Special features like translators, recharge stations, things to figure out...  It'll be fun. Sorry--we could tell you more, but then we'd have to kill you.  Not worth it.  Save the killing for the aliens.

We might sneak a bit more information under the fence in a month or so, though, just to get the hit count up on this page.

Ultimate Invasion separation

The Ultimate Invasion project,
which was really always a private project by Paul "Moe" Fleschute and some friends, will continue its activity separately.  We'll still give them a place to put a web site and other TeamTNT facilities for meetings and project stuff, and most of the team members are also TeamTNT folks, but it won't be an official TeamTNT project.

TeamTNT will only have one active project at a time from now on.  Having 3 at once has been too much conflict, has caused delays in all 3 projects, and has drained a lot of team energy that should have been spent on our real project, Doom2000.  Moe will have his Invasion web page updated in a few days--the link is above under the "Friends of TeamTNT" section.


Since id Software GPL-released 
their DOOM source, we've been approached by folks to get us to do the same with the Boom source. 

We've done so, and it has been uploaded to  See the Boom pages for links.

There aren't any feature or code changes to the game--it's all about the licensing and what you can now legally do with Boom source code.  The 2.02 version was our last version, as we already stated about a year ago.  

From our Boom FAQ:

I want to use BOOM in a game of my own.  Is that legal?

Yes, within the specifications of the GNU Public License (GPL).  From the "ABOUT.TXT" file:

This release of BOOM does not involve any changes in the binaries or
sources from the v2.02 release, it is simply a relicensing of BOOM
under the GPL. The old license file DOOMLIC.TXT has been replaced by
a new one, COPYING, copied verbatim from the pages of the GNU
organization (Free Software Foundation). This was undertaken only
after permission had been obtained from all copyright holders: id
Software, Chi Hoang, Lee Killough, Jim Flynn, Rand Phares, and Ty

The main purpose of relicensing was to clear the path for works derived
from BOOM to also relicense under the GPL if they wish.

Note that this license only applies to this executable engine and its
sources. All artwork, sounds, music, and other intellectual property of
DOOM is not affected by this license.

Any questions regarding the license for BOOM should be sent to:

Jim Flynn

This license change only applies to BOOM, not its derivatives (such as MBF, PRBoom, etc.) unless those authors also so specify.

Some status blurbs
Got some applications, and some of the folks look pretty good.  We'll be selecting some over the next week or so.  If you're an expert level designer and haven't applied yet, the application page is still active.

The Return has had its final build for the initial release, and beta testing (private, sorry) is beginning.  Here's what's going to happen...  We're releasing 7 levels ourselves, plus the resource WAD file (it's a slightly enhanced version of the Eternal resources).  Here comes the cool part:   we're releasing the Eternal / Return resources for you to use on your own levels to your heart's content--just give us credit where due.  We'll even have a separate area on for your Return levels and we'll announce and index them on our site.    We've got some new screen shots too--go check 'em out.

How about Doom2000?  Sure, might as well tell you about that one too...  We've just done build 1, with 5 levels in progress.  We have several sounds, over 100 textures and mini-stories for the hubs defined.  It's looking pretty good but we don't want to get you too excited.   You know how you all got when id registered the domain, making up your own stories about what that meant (it's no longer a domain, BTW, if that tells you something).  Just sit back and relax--it'll be good when it's done.

Sunday 27 June 1999
New level designers needed for Doom2000
All previous applications have been canned.  If you submitted one before and weren't rejected, and you can qualify, then send in a new one.  We have a new strict test that level designers will need to pass before being considered.  The application has been shortened quite a bit and is specific to only what we need right now.

The only thing we want is expert level authors for the Doom2000 project, and we need them now.  See the application page for specific details about what we need, and if you can make the cut, let's see what you've got to offer.

Doom2000 naming contest winner
Long week, huh?

Well, Dave Razor is the new name of our hero in Doom2000, suggested by "Nechuta".  We're getting in contact with the winner now to be sure we got a valid email address on the submission.

The prize, you ask?  Well, we're going to be making some cool TeamTNT/Doom2000 T-shirts for our project members, and one of those will go out as a special prize for this contest.  Of course we won't be having those shirts made quite yet, so it's kind of a future promise.  Gonna have to trust us...   At least one person's going to be eager for us to get Doom2000 done... :-)  We were considering a trip for 4 on the QE2's Millenium cruise, but that's about $43,000 per person so we chose the T-shirt instead.

We whittled the whole list of 75 or so submissions down to the top eight and then the Doom2000 project team voted on them.  Dave Razor came out on top at 59 points, followed by Dixon Blake at 53 (close second), then Kan Drykis, Nick Freeman, Kerry "Deathstorm" Sundstrom, Picfar Rudgard, Dhaisan Dreigan and Tor bringing up the rear.  Thanks to all who participated, even the ones who didn't read the rules.

Friday 30 April 1999
Doom2000 contest closed
The Doom2000 "Another name for Horace" contest is now closed.  We'll be announcing the winner in the next week or so.

Doom2000 level building starts tomorrow.  All levels have been defined and level authors have signed up for their initial ones.  There has been lots of general discussion and further development of the alien language too.   You didn't think that 3-character Doom2000 logo was just a graphic did you?   It really means something.  This is going to be cool.

Sunday 4 April 1999
Doom2000 web site opens
The Doom2000 project has its own web site.  Drop by and read the storyline. 

See if you're clever enough to participate in the contest.

Saturday 20 March 1999
ZDoom is officially endorsed by TeamTNT
TeamTNT hereby officially endorses use of the ZDoom engine, coded by Randy Heit.  It supports Boom-based wads very well, has a large number of other enhancements, runs in Windows and DOS, has Internet play and good sound and many other features.  The ZETH editor, a modified version of the DETH editor widely used at TeamTNT, supports the ZDoom features.

TeamTNT created Boom as a stable base for the editing community to use for new levels as well as for other coders to use as a base for their engines.  ZDoom has used many if not most of the ideas, enhancements and bug fixes that we put into Boom and reflects exactly what we had in mind.  Since we will no longer be enhancing Boom, it is with pleasure that we endorse ZDoom as the heir apparent of the DOOM "Source Ports" for general use.  See other entries in today's news for details of how we'll be using it.

Thanks to Randy Heit for a job well done, and to all the other folks he credits with ideas, code and techniques he has incorporated.

ZDoom selected for new TeamTNT projects
Both Doom2000 and Ultimate Invasion will be built using ZDoom features. 

Ultimate Invasion will not be heavily modified from the current 99-level plan, but will make use of some of the per-level features and internals. 

Doom2000 will be a considerably enhanced product over what would be possible with Boom or DOOM alone.  Since design has just begun on Doom2000, it's difficult to say how extensively all of the ZDoom features will be used, but you can bet it will be a great product because of it.

The Return will remain a Boom-designed set of levels.

Doom2000 design begins
The design for Doom2000 has begun, with initial participants being identified, mailing lists set up, storyline written and some really cool new ideas are churning.  We'll keep you updated as we go.  The official beginning time for the project is April 1st, so this next couple of weeks is still preliminary work.  Just thought you might like to know...   We'll have a site up around April 1st with additional details.
Sunday 28 February 1999
You're not bored any more.
OK, Reclamation is out and ready for you.  32 more DM levels from TeamTNT, this time incorporating a bunch of the cool gameplay effects available with the Boom engine.  Be the first on your block to frag someone riding by on a conveyor, dive underwater to avoid a rocket, or even experience the afterlife (it's worth getting killed for).  Lots of new textures, a storyline to go with it, and did we mention 32 more levels?  Thought so.  Go get it now.

That makes 147 DM-only levels from TeamTNT, to go along with our 128 Solo/Coop ones.  And there's always more to come...

Friday 5 February 1999
Reclamation Beta Testing closed
The Reclamation beta testing signup period is now over.  Thanks to those who signed up.  Now give us a couple of weeks to test and a week to get it out and everyone  else should have it to play with by the end of the month.
Sunday 31 January 1999
Reclamation Beta Testing signup
Interested in being a beta tester for us on Reclamation?  You have until February 4th to sign up for the two-week testing period.  Go to the Reclamation page to sign up for this unusual opportunity!
Sunday 17 January 1999
New Reclamation screenies
Another ten screenshots from the nearly completed Reclamation deathmatch megawad. 

Keep your eye out for this one to be released within about a month.

Plutonia Experiment superfast demos
Wow.  All 32 levels of Plutonia on Ultra-violence in two hours?  Yup, it's been done and is available for your enjoyment.  Go get it!
Saturday 16 January 1999
Ragnarok has been put on hold
We have decided to put Ragnarok on hold, and will instead be using the work so far as the background for a new project using the upcoming OGRE engine.  The name will be retained, the story and effects will still be done, but it'll be pretty much restarted in a new environment.

We see this as a perfect opportunity to use the Ragnarok story and features that we've already planned and worked with, to make both the OGRE engine do what we need and to use the flexibility of OGRE to make Ragnarok what we really wanted it to be.  All this will be without the headaches of DOOM limitations, even though it's better than it was because of the various source ports.  OGRE is a different engine though, and Ragnarok will make the perfect test case for building a better engine.

For more information, including the first full 8 chapters of the storyline (which is about half of it), select the Ragnarok link above.  We will also be sharing some screen shots over the next few weeks, to give you a flavor for the huge effort that has gone into it so far.  We are far from abandoning the project.

Hint for Final DOOM TNT:Evilution MAP30 with BOOM
TNT:E MAP30 has some steps near the red key and in the final room that won't build right if you use Boom.  We fixed the stair building bugs that were in DOOM, but in doing so made it incompatible with some wads that weren't quite created correctly.  All you need to do is to type the compatibility cheat TNTCOMP as you get to MAP30 and we'll use the DOOM-compatible way of building stairs.  You should make a note of TNTCOMP as something you can try in any wad that seemed to work OK with DOOM but not with Boom and its descendents.
Monday 7 December 1998
OGRE - the Open Gaming Resource Engine - is announced
Open Source Project for the next DOOM engine

The Open Gaming Resource Engine project has been launched.  This is a manifestation of the "Merger" project among members of leading DOOM source code projects, and will be an open source project.   Instead of another proprietary closed programming effort, this is a chance for the entire DOOM community to be involved in the next engine.  It will be an unprecedented approach to engine, utilities, level and graphics creation, and much more.  Rather than expound in this announcement, we'd like to direct you to the home page of the OGRE project, at: (defunct address--link removed)

Much more information is provided there on all aspects of the project, or at least as much as we know now.  Members are joining and contributors are making themselves known.  Initial architecture and design is being determined now, and open discussions will be taking place as we progress.  We will have frequent updates and sharing of information on the site, so even if you don't plan to participate in the project directly, you can stay tuned.  We'll have a discussion forum as well, though that's not ready yet.  The Ogre has landed...

Sunday 15 November 1998
PRBoom version 2.02 released
Compatible with BOOM 2.02

Version 2.02 of PRBoom for Windows (Win95/98/NT) is now available.  This port of Boom 2.02 was done by our own TeamTNT member Florian "Proff" Schulze and therefore is now an official supported port of the product.   It has high resolution (up to 1600x1200 even) and IP-type multiplayer ability.   Give it a try!  Source is available. Go now

Friday 6 November 1998
More Reclamation screenshots
Feel free to drool.

Reclamation now has 26 levels done or nearly done, and another batch of screenshots is waiting for you.  Go now

Thursday 22 October 1998
BOOM maintenance release 2 is ready
This is the last version of Boom.

Many fixes have been implemented, some more obvious than others if you don't go look at the list of changes.  Or just go get it if you're impatient.

Here's a sampling if you don't want to link to that page:

Firelines, another kind of "slime trail," are a thing of the past.  Blockmaps for big maps are calculated much faster now.  Slowdowns underwater have been fixed.  Sound persistence in sectors now carries across savegames.   Improved network code--those jerky games in earlier Boom versions shouldn't be a problem now.  Final DOOM episodes now show the right map names and intermission texts.  BEX allows named bit fields for monster characteristics (huh?).   Par times parsing fixes in BEX. Stair building code improvements.  There's more--go look at it.

Something maybe a bit more obvious when you're starting up a game:

You don't have to put -file or -deh or -loadfile on the command line any more if you don't want to.  Instead of:
  boom  -file   abc.wad  def.wad  -deh  abc.bex  xyz.deh  -playdemo   mydemo.lmp
just type:
  boom  abc  def   abc.bex  xyz.deh  mydemo.lmp
Boom is smart enough to figure out what's going on by the file extensions (none means it's a wad file).  Just drag a wad onto Boom in Windows and it'll start playing.

Also, just supply -warp on the command line without any map number, and Boom will go to the first map in the loaded pwads.  No more going around trying to figure out where that level loaded.  Like:this:
  boom otherwad -warp

Last version, you say?

Yes, this is expected to be the final version using the Boom source code base.  The new work we're going to do is all going to be on the as-yet unnamed merger engine.  That doesn't mean we're throwing away what we learned so far, but it does mean that we're rethinking the engine in more general and effective ways and will be moving forward instead of being locked into working on Boom forever.   It's a relief.

And the source?

Available right now.  Just Go Get It.  Enjoy!

Sunday 18 October 1998
BOOM maintenance release shortly, more changes
Release within a week

We think so anyway.  Boom 2.02 has been stable in testing and we think we're about ready for a release.  A few more items have been added to the list of stuff we've fixed in this, our final release of Boom.. Go now

Reclamation progress and screenshots
Deathmatch wad progress

As you well know by now, we don't update the page every time we make a level, and give you empty screenshots of work in progress.  We have 22 levels of Reclamation now in the current build, most either finished or undergoing final review and tweaking.  Using Boom has been a real eye-opener and you're going to see some effects you never thought about before.  We'll put up 3-4 screenshots every week or two, and the first batch is ready now. Go now

Ragnarok is alive
Rumors of its death are greatly exaggerated

There's some new life in the old project...  We're still a long way from ready with this one and experimentation continues on several fronts but there have been some interesting discussions and activities lately.  It's been converted to Boom, and further source mods are being designed.  New members have joined too.  Just in case you thought we'd forgotten... Go now

Saturday 3 October 1998
Next BOOM maintenance release changes
More to come with BOOM

A new release of BOOM is due in a week or three (probably mid-late October) and there's now a list of 30-some fix and enhancement areas that will be part of version 2.02.  Read and drool.  Note that this will be our last update to the current code base.  All future engine work will be done on the merged engine project. Go now
