Infestor is a puzzle platformer in which you play as a blob on the run. You can't move fast or jump high, so you will need to rely on your body-snatching ability to make it to freedom. Get close enough to humans to take control of them, and then use their abilities to overcome obstacles. Be sure to sneak up on humans with weapons as they will kill you on sight. Complete each level by exiting the pipe as your blobby self.
