In the game, players must move Kapt. Krooz'r to a rotating mothership at the top of the screen and enter it to complete the level. In the player's way are alien ships that must be taken down with a beam that can be fired in eight directions. They also have the ability to deflect enemy fire back at them.
Uniquely, the game's mothership is an actual plastic prop attached to an electric motor which is reflected onto the top of the screen by a series of mirrors.
This game has the following tropes:
- Bonus Round: Every five levels Kapt. Krooz'r is taken to a galaxy of planets and must pick up space junk within a time limit.
- Endless Game: Like most games of the time, it only ends when you use up all lives.
- Visual Effects of Awesome: The flying saucer considering that it is a reflection of a real object being projected onto the screen.
- Xtreme Kool Letterz: The game's title replaces "c" with "k", uses an "oo" for "cruiser" and also uses a "z" instead of an "s".
- Video-Game Lives: Played very straight with the player earning a bonus life at regular intervals.
