As expected, a playable demo of UFO: Alien Invasion is now available for download, allowing you to try out this turn-based tactical combat strategy game inspired by the X-Com series and powered by a heavily modified version of the Quake 2 engine. Please note that this is a technical demo only, and a lot of things have not been implemented yet or will change during development. In this tech demo, you can create a team, buy some weapons and play three "terror" missions.
