Island Escape was a multiplayer map in Ratchet & Clank: Size Matters. In the challenge, you must work with your team to find or create power cells and bring them to the generators on the map. After you have fully powered the two generators, a bridge will form to your home base. You must power the generator and then turn the bolt crank to escape the island.
"Island Escape – Players race to collect radioactive cores and use them to be the first to launch their rocket to freedom. Be careful not to hold onto the core for too long though! Prolonged exposure may result in mutations."
