Mad Marco is on the rampage and has blown the bridge to the mainland. The only escape for the fleeing population is to jump into the shark-infested waters. As Lifeboat Lennie you must try to bounce the panicking people to safety across the water whilst avoiding the marauding sharks and the desperate attempts of Mad Marco to blow up your liferaft with dynamite.

Lemming Syndrome is a fast and furious game full of special effects and options designed to make your task harder as you get better. The options page allows you to select the speed and the type of control for your raft. You have only one liferaft and the game ends if more than fifty people are left to drown.
