Terminal City, 2025. A mysterious virus killed millions of people and turned hundreds into blood-thirsty creatures. Helpless in the face of this terrible virus, the Government is developing a video game called Dead Trigger that puts into scene the terrifying events that have led to this curse that seems endless. Players who kill most zombies in the game are recruited to fight the horde of zombies in real life. Led by Captain Kyle Walker, the team heads to Terminal City to find out the origin of this epidemic and find a team of scientists working for years to find an antidote. The only way to reach them is to pass through the creatures.
