You and your team are trying to survive the zombie apocalypse. There are rumours of a doctor that may have an antidote that could stop the infection and save humanity. Your eclectic group of survivalist scientists are on a mission at the bunker where the doctor was last seen. You must get in, secure the location before the zombies know you’re there and then find the antidote before it’s too late. Work quickly and quietly as a team if you want to survive. If time runs out instead of escaping you’ll become . . . The Undead!
