Dead Zone: Reboot

A failed game developer dies in a server room explosion and wakes up to find the world has been reformatted by a System. The monsters? Corrupted versions of the game he spent three years building. His insider knowledge of the codebase gives him an edge no one else has — he can predict attack patterns, find hidden quests, and exploit system bugs. But someone else knows about the connection between the game and the apocalypse. And they want to control both.
