Two distinct characters called Mr Head and Mr Heels are played in this arcade adventure. They are separated at the shoulders but capable of joining together to maximize their abilities in some situations (but reduce them in others, so they can be split again). The game is presented from an isometric perspective, and presents the characters with a number of puzzles involving switches, jumps and climbs. The levels are 3 dimensional, and the characters must collect crowns as they progress. Objects can be picked up and manipulated as necessary.

A game remarkably similar to Lode Runner, you play an astronaut with limited oxygen (time) chased around by various space aliens. Your only method of dealing with these multicolored threats from space is to dig a hole, lure it into a hole and then manually fill up the hole with the alien in it. Dropping aliens on top of other aliens earns you extra points and eliminates both. Levels get progressively harder and enemies grow faster.

Abe’s peaceful retirement was shattered when visited by a vision from the Three Weirdos. Abe learned the Magog Cartel was mining Necrum, the sacred Mudokon city of the dead, to collect bones to make super-addictive SoulStorm Brew. After freeing the Mudokon spirits imprisoned in the Mudanchee and Mudomo Vaults, Abe gained scary powers from the Weirdos, including the ability to heal his Mudokon friends of SoulStorm addiction, and the power to turn invisible. Infiltrating the transportation hub of FeeCo Depot, and using explosive farts to survive adventures at the Slig Barracks and Bonewerks, Abe broke into SoulStorm Brewery. There Abe learned the truth behind the secret ingredient of SoulStorm Brew... just before blasting the place to atoms with the combined power of the sobered-up Mudokon he’d rescued. Then Abe joined his brew-addled pals at Alf’s Rehab & Tea to take the cure – the journey of a lifetime starts with one step. Or is it twelve?
