What exactly is UFO Alien Invasion

Well, UFO Alien Invasion is a game in which a player fights brutal aliens that are trying to take control of the planet Earth.

How do you play the game

Simple, you build up bases, make a team, and get engaged in a combat. In short, you have to prevent invasion of your area by aliens. The carefully designed turn-based system offers you pin-point control of your squad over enemy and at the same time maintains steady pace of the game.

The game includes two main modes of play namely,

In addition, you can build, buy and produce anything as long as your budget allows it and even launch interceptor aircraft to shoot down UFOs. Geoscape mode also employs easy-to-use time buttons to control the passage of time (the game can be paused anytime without interrupting the play and resumed when required).
  • Tactical mode – Here, you are supposed to take the command of your team in various missions to fight against the aliens wherever they might appear. You can use fire weapons, grenades and other equipment to accomplish your mission. Note that mission objectives vary for each mission and the difficulty level rises with each subsequent mission.

    I tried it on vista 64x, and it keeps crashing. There is no troubleshooting for that, all is lost.
