ZRPG

You let them in. At first, they seem to be adapting well, but then they fall sick. One night, it is noted that they died of a flu. You go back to bed, feeling quite sad. You sleep soundly for a couple of hours, then wake up to the sounds of screams and automatic gunfire. The bodies turned! Finally, it is all over and half the population of the base is dead, including soldiers. The marine you argued against grabs his rifle, and shoots the cook, then turns on you. You scramble away, but his bullets strike true. You fall to the ground, dead.
