UFO: Alien Invasion is a 3D UFO-inspired tactical game.
UFO: ALIEN INVASION is a strategy game featuring tactical combat against hostile alien forces which are about to infiltrate earth at this very moment. You are in command of a small special unit which has been founded to face the alien strike force.
To be successful on the long run, you will also have to have a research team study the aliens and their technologies in order to learn as much as possible about their technology, their goals and the aliens themselves.
UFO: Alien Invasion is heavily inspired by the X-COM series by Mythos and Microprose. The first game of the series, UFO DEFENSE, became a classic and, in our honest opinion, is one of the best games ever made.
UFO: Alien Invasion is neither a sequel nor a remake of UFO DEFENSE - we simply had the urge to create a similar strategy game, which will hopefully be as entertaining as the original was for the players (and for the developers, of course). Join the IRC-Channel at irc.freenode.org named #ufo:ai and contribute to the developing process.
Gameplay:
The game is turn-based. Well, this might sound somewhat old school now, but trust us: turn-based games are fun!
Each member of your squad has a limited number so called "time units" each round, which are consumed when you order the unit to walk, to fire a weapon or to perform any of the other miscellaneous actions. When all your forces are out of time units, the aliens turn starts. In addition to eliminating as many enemies as possible, your mission is to minimize civilian casualties as well as to acquire parts of the advanced alien technology.
Once youve acquired sufficient samples of the unknown technology, your research labs will be able to reproduce the alien weapons and devices in order to use them against their original creators.
Game Engine:
The game engine is based on a heavily modified version of IDs Quake2 Engine. This doesnt imply that UFO: Alien Invasion is a mod or a total conversion at all! No, UFO: AI is a stand-alone game which doesnt require Quake2 or any similar program to run. Our self-developed game engine is featuring up-to-date OpenGL graphics and special effects, increased texture resolution, hardware accelerated clipping of map layers to toggle between floors, a new animation system for player models, a stunning AI and a few other gimmicks.
Multiplayer support:
You can play UFO: ALIEN INVASION with your friends via LAN or Internet. One player takes the role of the human special squad while the other is in control of the alien invaders. Co-op team play with multiple players on both sides is also supported for up to three teams on each side (6 players total).
Enhancements:
- Implemented sv_roundtimelimit cvar to set the maximum time a team has to finish their round in multiplayer.
- Completely rewritten saving and loading system.
- Finished implementation of Flashbang - now Flashbang will disable enemys reactionfire as well.
- Reintroduced employees renaming again.
- Hire menu and Team Select menu now shows Health bar as well.

Misfit Model 3D is an OpenGL-based 3D model editor that works with triangle-based models. Misfit Model 3D supports multi-level undo, skeletal animations, simple texturing, scripting, command-line batch processing, and a plugin system for adding new model and image filters.
Complete online help is included. It is designed to be easy to use and easy to extend with plugins and scripts.
Misfit Model 3D was written and tested on Linux (2.4 and 2.6 kernels) and has been compiled and tested on most major Linux distributions.
It is not endian-safe so it is unlikely to run on non-x86 hardware platforms--this will probably not change soon unless I get requests for a version thats usable on big-endian archs.
Enhancements:
- The menus have been re-organized. There is a new command to make normals face outward. The texture coordinate window now has a rotate tool. Material support for COB has been improved. Many animation bugs have been fixed. A "File | Export" command has been added to indicate which formats have less reliable write support.
