You were deep in the sea, when the ship's radio starts blaring. "ICE AGE! ICE AGE!" repeated for several minutes until finally, "DO NOT SURFAC-" the channel was abruptly cut off. You, amongst five other crewmates are forced to survive on a submarine, the Intrepid, the most modern nuclear submarine, able to go for hundreds of years without needing to refuel. Your only food sources is a small, improvised radish and potato farm, canned stew and corn and a dozen MREs.
