Somer Assault, known as Mesopotamia in Japan, is a video game developed and published by Atlus in 1991 for the TurboGrafx-16. This side-scrolling action game features an unnamed pink Slinky object/creature as the protagonist which can fire bullets from its sides, jump, and slink along walls in its quest to stop an evil sorceress. The title is a play on the word somersault, as the Slinky somersaults around the stage while assaulting enemies.
