Alien Arena is a standalone that combines a sci-fi atmosphere with the tournament style deathmatch of Q3A and UT2k4. With major graphical features such as GLSL per-pixel lighting, ragdoll physics, light blooms, real time lights and soft shadows, Alien Arena brings a level of beauty and immersion not generally seen in deathmatch. The game also includes mutators, adjustable effects, bot skill settings, and fully configurable deathmatch, team deathmatch, CTF, All Out Assault, Team Core Assault, Cattle Prod, and Deathball games.

Martian invaders. Dm-Chasmatic remake! Martian Warrior Extermination, room of carnage.

The game features original artwork, with with a dark sinister atmosphere combined with an off-the-wall campiness, and trippy, techno type music. There are currently over 60 maps, loaded with weapons(each having an alternate firing mode) and powerups.

Alien Arena has fast, smooth gameplay, and players can play online against one another or against the bots, which feature multiple skill levels, and will rocket jump, strafe jump, and taunt you mercilessly.

Way back in early 2008, Alien Arena received a major graphical overhaul, updating all of the player characters and many other items. Generation 2 served us for six years, slowly evolving over time as changes in the rendering engine came, to take advantage of new features. Well, six years is a long time, and the decision has been made to move to Generation 3, starting with the player characters all receiving updates. In some cases, the entire mesh has been reconstructed, in others portions have been redone, or enhanced. Skins will all be redone either completely or whatever portions are needed to bring the standards and consistency to current levels. Some weapon models will also receive either updates or be completely new, with only a few remaining unchanged, as some of them were more recently constructed, and others updated already(can you believe the blaster mesh has hung around since 2006?). Powerups were all very recently updated so those will remain as is for sure.

As of this writing, four of the nine characters have been completed. Here are some images of the updated versions of the Martian Warrior, Commander, and Slashbot. For "before" images you can peruse the images here on or the official website.

Polycounts have are roughly 50-90% higher, and the UV layouts have been optimized to allow for more detailed, sharper texturing. Performance in normal gameplay should be completely unaffected due to the rendering changes made over the past year. Our tests in very extreme scenarios(i.e, filling a room up with fifteen Martians clumped together) showed only a small decrease in framerates on a variety of platforms. As you can see the look of the game is evolving, while Generation 1 was quite campy and silly, Generation 2 took the game to a darker, more sinister look. Generation 3 is furthering that trend, moving it towards a more "horrifying" visual...the stuff nightmares are made of! Just wait until you see the new Overlord model...

The other change that will occur is that a number of levels will be receiving updates. We are currently working on a new terrain rendering system, that is in it's early stages, and working very well thus far. Some levels will be receiving terrain bits where appropriate, and some other updates. As in the past, we may cull out some levels that are dated and just not worthy of continuing to be part of the base game. It's also possible that some game types such as Deathball and Cattleprod may be relegated to the archives, as they never proved popular at all and maintaining them and their levels will dilute our efforts to push the game forward.

The tactical version of the game is also proceeding as planned, and we are busy working on content and other gameplay enhancements that will be discussed in further news updates. We expect all of this to be released some time this Spring, which will include the full demo of Alien Arena: Tactical.

Wish they would release/post a legacy version. One prior to needing physX, or whatever graphical enhancement made it not play on my old machine anymore. It may not be compatible with the current version, but it was still fun to play on older hardware. If you have problems installing, you may need dev packages (libcurl_dev, and etc.)

Via SVN, currently "the engine" is actually the game. You will need the source code however, that you can get from SVN.
