Atomic Robo-Kid

The Earth colony of Terra-12 is almost destroyed by an alien invasion and radiation. The little fighting robot Atomic Robo-Kid is entrusted with saving the colony. You have 28 levels to complete and clear of enemies. This is a shooter, and Robo-Kid can fly, which makes the gameplay similar to a regular horizontal-scrolling shooter, but with the ability to move in the opposite direction. Defeated enemies sometimes leave behind gems that can be collected for additional abilities, including weapon upgrades.
