While the Marines of Alpha Company are preoccupied with the hordes, Dr. Tanaka enacts his cunning escape plan. With their backs turned the Marines never see it coming. Tanaka releases a noxious gas into the colonies ventilation system. It blinds, dazes, and confuses the marines. While surrounded in the thick green gas and suffering from its effects, the marines stumble blindly, and are separated.
Players will find their character in a random part of Apollo, their screen will have a green tint, and their camera will be erratic. It is best to regroup immediately. Once everyone is safe from harm, you will need to split up and search for Tanaka.
