Flockers

There is no escaping the Worms weapons factory without blood, sweat, tears and mutton chops. Your goal is to have one sheep survive the traps and hazards separating the flock from the exit, using animals as barricades and short stairs, or imbuing them with special abilities. However sheep (unlike, say, lemmings) hardly have any means to alter their environment, so you'll have to learn each level's logic through trial and error to guide the bleating lot through Team17's surprisingly heartless puzzles... Then try to top their cruelty using the aptly-named Meat Maker editor.
