Robbo is a side-scrolling puzzle solving action game, similar to Boulder Dash and Sokoban. The player directs the robot, named Robbo. His goal is to collect all the screws on the planet needed to repair the ship and reach his flying capsule, avoiding alien forms of life and numerous traps. The players will encounter many obstacles on their way, for example chests that will have to move properly, closed doors requiring to find the key, deadly cannons or electromagnets attracting metal objects. Robbo can use the gun after finding ammunition, bombs placed on the board and travel through teleporters. The original Atari 8-bit version has 56 levels, the DOS version added four additional levels for a total 60, and the Atari ST version has the original Atari 8-Bit levels plus an additional 80 levels for a total of 136 levels.
