Take a wild guess at what a game called "Alien Shooter" entails. You're right! In Alien Shooter, you shoot at aliens. The game takes place from an isometric perspective, and you control a man or a woman with the task of running around a variety of facilities, turning on the power, and blasting aliens with a handful of different weapons. You run around with the keyboard, and the mouse is used to aim and fire. Generally speaking, it works pretty well; but all in all, the game feels like a clunky take on the same aim-and-fire mechanics used in Crimsonland. Also, enemies and power-ups can often hide themselves up against walls due to the game's isometric view of the action. While the game does have some depth to it--you can purchase additional weapons--the action is generally unsatisfying, though the way that all the corridors get smeared with alien corpses and blood after a prolonged firefight at least looks nice.
