Dr. Chaos was your typical mad scientist. He owned an extensive mansion and spent his time experimenting within it on things that mankind was never meant to know. His latest invention is an Interdimensional Warpgate which allows access to worlds beyond our own. As the doctor's younger brother, Michael, you arrive at Dr.Chaos' mansion one day to find the place crawling with strange mutant creatures. To make matters worse, the mansion itself isn't looking too good. Strange "holes" into other dimensions have opened up and made a mess of the architecture. Furthermore, Dr.Chaos himself is missing.

The game takes place as a platform game where you must use various weapons (knife, pistol, machine pistol or grenade) to fight your way past mutants and into various rooms of the mansion. Once in these rooms, the view changes to a first person maze... and you'll need to open various cabinets, doors and hit walls in special places to find access into a dimensional hole. Once you enter the dimensional hole, the game once again becomes a platform game, where you will need to fight your way to the end of the level and defeat a boss monster of some sort to obtain a piece of the Warpgate. Then you'll have to proceed BACK through the level and return to the mansion, where you'll explore to find the next dimensional hole.
