Ah, lemmings. They're goofy, they're cute, they're expendable. For whatever reason, these creatures need to migrate from point A to point B, and it's your job as overlord to get as many lemmings to the level exit as possible. To accomplish this, you can assign the lemmings various duties, from bridge building to parachuting. On more difficult levels it can be a real puzzler figuring out how to get the little buggers to the exit. But there is a dark reward for the overlord who falls short; seeing lemming after lemming splatter onto the ground is not unamusing.
