Following the Ground Zeroes Incident, the surviving MSF members bury their dead at sea with aid from the UN. A UN member requests to take the body of a fallen soldier. Shortly after the attack on MSF, a large wormhole opened above the base. Though the soldier was able to avoid being sucked into the wormhole, their left arm was severed as it closed.Six months later, the soldier awakens in a facility managed by Wardenclyffe Section, a government research group investigating infectious organisms and wormhole technology. The UN member, Goodluck, one of Wardenclyffe Section’s chief researchers, enlists the soldier to enter another wormhole to reach Dite, a hostile and desolate alternate dimension. The soldier was chosen due to being infected with an organism from Dite via contact with the wormhole, which restored their severed arm but puts them at risk of becoming a Wanderer, former humans rendered zombie-like from the disease. Goodluck gives the soldier the moniker of “Captain”, instructing them to find a cure and to rescue other people transported to Dite through wormholes.
