After a mysterious virus kills billions and creates scores of zombies, the government develops a video game - DEAD TRIGGER - that simulates the outbreak, then recruits the game's best zombie killers to combat the real-life horde. Led by Captain Kyle Walker (Dolph Lundgren) to Terminal City, the virus's point of origin, the player's mission is simple: find the team of scientists working on a cure. But wiping out the city's undead legions will test every DEAD TRIGGER skill they possess.
