The Epicenter

The Diver is sent on a mission to the Epicenter between two twin worlds, when his A.I. Fairy manages to sync up with her alternate self, becoming all-seeing and omnipresent. Both Divers must fire upon what lies at the Epicenter at the same moment, otherwise both worlds will perish. However, one of the worlds is doomed to die regardless no matter the outcome... which world will survive?
