Jailbreak in Space

Jailbreak in Space is a variant of the arcade game Cosmic Guerilla. It's a fixed screen shoot 'em up where the player's task is to defend a jail that holds three alien prisoners. The jail is located in the middle of the screen and alien space ships move towards it from the sides, ripping it apart one brick at a time. The player has to prevent them from doing this by shooting at them from the bottom of the screen and at the same time avoid being hit by the projectiles they drop. Barriers similar to Space Invaders offer some protection. Points are earned for each alien shot down, and extra points are earned for those carrying a brick as well as the escaping captives.
