Panik

Panik is a side-scrolling science fiction-themed arcade game for the TRS-80

Trapped in an enemy building site, and out of ammo, the evil Mzors rapidly close in. The player controls a small character who can move horizontally on a series of platforms that scroll horizontally. The player is armed with a small laser gun, but initially has no ammo and must pick up ammo packs as he explores the level. Ladders allow the player to move up and down. The goal is to destroy as many varied aliens as possible, but if the enemy touches the player they lose a life. The player starts with 3 lives, and it's game over when all are lost.
