You were a technical support engineer on a geoforming outpost on LV-513, tasked with changing a very important light bulb when the outpost was overrun by a hostile alien lifeform. During the attack you managed to grab some supplies and lock yourself into a maintenance room. After some days, the noise and the screams from outside slowly die down. After some weeks, your supplies slowly run out. Time to head out. See what's going on. Find help. Survive.
