I Am Gamer follows Nathan Ledge, the last known Gamer alive after the fall of society. The story centers around his attempts to survive the post-apocalyptic world filled with crazed survivors and the Infected (zombified creatures of gaming lore). Before the fall Nathan was a world-renowned computer scientist who headed the task force: C.I.G.S. (Creative and Innovative Gaming Solutions). Their goal was to develop gaming solutions to real-world problems, in hopes of creating a utopia. But when gaming went too far, addiction led to a viral infection that corrupted users and effectively destroyed the civilized world. During this time most gamers were captured or killed by survivors who blamed them for the crisis. One gamer, resistant to the infection, made it out alive. After years of isolation and unsuccessful attempts to cure the virus, Nathan soon finds out that the last gamer on earth is not alone.
