Alien Crush features a science fiction theme reminiscent of the film Alien. Essentially, the player is "fighting" against the aliens with their pinball skills.
The playfield of Alien Crush consists of two main screens arranged vertically, with a pair of flippers at the bottom of each. The play stops momentarily as the ball shifts from one screen to the next. There are also several hidden/bonus rooms. These hidden rooms mainly involve destroying all the aliens (or several waves of aliens) for bonus points.
The player is given the choice of a fast or slow ball speed and two different music tracks.
