Jetpack is a platform game available as freeware, developed by American studio Adept Software and originally published as shareware by Software Creations in 1993. The object of the levels is to collect all of the green emeralds scattered around the level while avoiding obstacles and enemies. Once accomplished, a door opens which the player must go through in order to advance to the next level. There is a single player, and a local multiplayer mode. The multiplayer mode supports up to eight players, where players take turns on the same machine.
