It is the year 2084 and you are the head of a special small unit in charge of protecting the planet from an alien enemy. Set up your bases, prepare your team and take part in this fast and fluctuating strategic combat game.
UFO: Alien Invasion is a free version of the classic X-com strategy game. You will also have to design a base, hire an elite squad and do technological research. That will be the only way to combat such a powerful and cruel force.
UFO: Alien Invasion is based on the Id’s Quake 2 engine, but this has been largely modified to attain great graphics and detailed view level.
Just like X-COM, there are two different ways of playing it. The Geospace mode and the Tactical mode. Using the Geospace mode, you can control bases, facilities and units. You can investigate new technologies, send interceptors to eliminate UFOs and send troops in response to alien activity. When using the Tactical mode you can combat with your squad, and give them orders to move, fire, launch missiles, etc.
It also has a multiplayer mode, which makes it possible to play one on one or in teams up to a maximum of 6 players.
