Gary Peterson thought surviving the Citadel's first level was bad.
Then the doors started thinking for themselves.
Node 3-A has barely finished bleeding when a new nightmare comes walking down the Network Service Road: the Broken Door King - a towering horror made of shattered doors, chains, failed rescues, and emergency systems that have forgotten the difference between saving people and taking them.
Now rooms are converting into machinery. Rescue doors are eating the desperate. Clean air comes with hidden costs. Water systems want human load. White chairs are appearing everywhere, and Gary has developed a very reasonable policy:
Do. Not. Sit.
Armed with a battered mechanic's attitude, bad knees, a hidden class no one authorised, and a borrowed spoon that absolutely deserves hazard pay, Gary must dig into the Citadel's next layer before the Continuity Office preserves everyone into something neat, useful, and not quite human anymore.
Because the dungeon isn't broken.
It's working exactly as designed.
And Gary is about to make that everyone's problem.
Perfect for fans of gritty dungeon LitRPG, hidden classes, system apocalypse survival, dark humour, brutal progression, broken machines, and heroes who solve ancient cosmic systems with tools, spite, and extremely poor self-care.
Grab The Broken Door King today and return to the Citadel - where survival is messy, rescue has teeth, and maintenance is very, very overdue.
