You are a member of Overstrike 9, a group of mercenaries that are usually called in to do work in the shadows. Your current job is to investigate the happenings at Hyperion Base, one of the government's covert bases that has gone dark. When the team gets there, they find the place has been ransacked and stumble upon an alien substance called Fuse. They are not alone, however, as a terrorist organization called Raven is also after the substance, which they end up stealing. It is up to Overstrike 9 to track them down and stop them.
