Cosmo Police: Galivan is a sci-fi action platformer released by Nichibutsu for the NES in 1988. Based on the 1985 arcade hit, the game puts you in control of a cybernetic officer exploring interconnected alien environments filled with hostile cyborgs, power-up capsules, and maze-like stage layouts.
