From Flying Frog's Website: "Take your surviving heroes back into the fray in order to save the world in this thrilling new scenario by Lead Designer, Jason C. Hill. This advanced scenario introduces some new rules and game concepts and uses ALL SIX of the L-Shaped game boards!" This scenario uses some of the as-of-yet unused tokens in the base Last Night on Earth game, specifically the numbered (1-6) tokens and the Bio Canister tokens. It also uses a brand-new board set-up: all six L boards and the center board in a new configuration.
