Alien Arena 2007 is a fast paced, retro sci-fi themed game jam packed with features such as over 40 maps, 7 game modes, game mutators, 11 player characters, 9 weapons (each with an alternate firing mode), and the Galaxy front end that includes a server browser, IRC client, stats lookup, and a buddy list to keep tabs on your favorite players. New for 2007 is Team Core Assault, a team based mode with frantic action and speed, loads of brand new maps rich with color and detail, and enormous enhancements to the codebase that improves speed, security, and stability. Enhancements such as weapons stats and winner's podiums add a little new flavor to the game experience. Now at version 6.10, the CRX engine now includes real-time lighting and shadows, vastly improved dynamic lighting, more efficient particles and weapon effects, improved shaders, lensflares, fog, music control, and optimizations to make it sleeker and smoother than ever before. With so much content and code being revamped, Alien Arena 2007 bears little resemblance to it's predecessor.

Alien Arena also has a large community that has made available a huge amount of add-on resources, such as maps, models, skins, and other nifty enhancements that are easily applied to the game if the user so wishes. The community can be easily accessed through the Galaxy front end, using it's chat interface, and is always eager to help with any questions or problems running the game. Player stats are globally tracked and accessed either through Galaxy or via the Alien Arena homepage. A number of clans are registered, and each week a tournament is held on Sunday, 6pm Eastern time. Players are advised to show up fifteen minutes beforehand to get the server password. Ladders and cups are in the process of being organized, and more information will be made available soon.

Alien Swarm is an overhead view tactical shooter modification for Unreal Tournament 2004.

Set in a distant future, the players take the role of a Commander in the Interstellar Armed Forces. They must guide their squad of marines through Swarm infested colonies, overrun bases and outposts, to achieve a variety of objectives. Featuring Assault Rifles, Heat Tracking Guns, Sentry Guns, Flamethrowers and more.

The top down, tactical shooter can be played by a maximum of 6 players in a co-op style. (You can play 8 in total, but then the game gets a bit crowded so we made it 6 by default.)

Choose from eight marines, with different specialties - medical, technical, explosive or weapons specialists.

It features a single mission mode and a campaign. Fight off the Swarm to increase your skills and earn medals for extra skill points.

Rows of aliens are marching around at the top of the screen and you must shoot them all before they destory you.

One game varation is "Swooping", which is similar to the arcade game "Galaxian." The aliens move back and forth at the top and occasionally swoop down towards you.

The other variation is "Marching," similar to "Space Invaders." The aliens march back and forth and, when they reach the side, move down towards you as a group. If they reach the bottom, the game is over immediately.

This game is designed for the Agenda VR3 Linux-based PDA. However, it's written in plain Xlib, so it should run on any Unix variant. (The graphics are just sideways)
