UFO: Alien Invasion is a strategy video game in which the player fights aliens that are trying to take control of the Earth. The game is heavily influenced by the X-COM series (mostly by UFO: Enemy Unknown). It is based on a modified id Tech 2 engine, and runs on Linux, FreeBSD, Microsoft Windows, AmigaOS 4, and Mac OS X for both PPC and Intel Macs. There is also a version for Android, published on Android Market.
UFO: Alien Invasion is a squad-based tactical strategy game in the tradition of the old X-COM PC games, but with a twist. Our game combines military realism with hard science-fiction and the weirdness of an alien invasion. The carefully constructed turn-based system gives you pin-point control of your squad while maintaining a sense of pace and danger.
Over the long term you will need to conduct research into the alien threat to figure out their mysterious goals and use their powerful weapons for your own ends. You will produce unique items and use them in combat against your enemies. If you like, you can even use them against your friends with our multiplayer functionality. UFO: Alien Invasion. Endless hours of gameplay — absolutely free.
Like the original X-COM games, UFO:AI has two main modes of play: Geoscape mode and Tactical mode. In Geoscape mode, the game is about base management and strategy. You manage the activities and finances of PHALANX, controlling bases, installations, aircraft and squads of armed-response troops. You’ll research new technologies and use their results in battle against the aliens. You’ll launch your interceptor aircraft to shoot down UFOs and dispatch dropships in response to alien activity across the globe. You can build, buy and produce anything you like, as long as your technology level and your budget will allow it.
Your mission objectives will vary for each mission, and there are many to perform as the aliens’ terrifying plot unfolds. You’ll have to watch your back, be quick on your feet, and take the fight to them.
If you don’t, humanity is doomed.
