Enemy Zero

Enemy Zero is a 1996 horror-themed adventure video game for the Sega Saturn, developed by Warp and directed by Kenji Eno. Players assume the role of an astronaut who awakens from cryogenic sleep to find her spaceship overrun by invisible creatures who are hunting and killing the ship's crew. They must navigate through the ship in a combination of puzzle-driven exploration rendered in full motion video and first-person shooter sections rendered in real time, during which they must rely on sound to either avoid or kill the invisible enemies.
