Nikolai is a simple Russian guy, a fan of shooting zombies in the popular toy "Death Sector." But his friend is not quite ordinary. Grishka, with the rare surname Ivanov, do not feed bread, let me delve into the computer hardware. He even decided to use his friend's hobby for his next invention. And Nikolai is only glad. After all, it's one thing to shoot monsters with a keyboard and mouse, another from a real AKSU! The only problem is not to lose the movement machine and not get stuck forever in the world of Mutagen, where hordes of zombies and mutants are guarding artifacts that have no price.
