A strange platforming game on a repeating tiled screen.

You play as a (zombie) prisoner, throwing 16 ton (hence the name) weights at your foes. The foe spawning is randomly chosen overhead by a reel.

These weights are tossed up and can destroy most anything, including you. You can break them by repeatedly bouncing off of them, or throwing more weights on top of them.

The difficulty increases rapidly, and has been called challenging by modern audiences.
