Great old classic, currently on sale. Had to have it in my library :)
Abe's peaceful retirement was shattered when visited by a vision from the Mudokon Spirit Guides. 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 Spirit Guides, including the ability to heal his Mudokon friends of Soul-Storm 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.
