For the many crimes they committed the outlaw worms were exiled to an island in the Pacific Ocean. Now they are trying to get back home. The objective of every level is to save a minimum number of worms (that differs from level to level) and get them to the exit. In order to do this you must use the action buttons in the bottom panel of the game screen. At the end of each level you'll receive a password for it and at the end of the final level you'll receive a cheat code that you can use inside the game.
