Madman Apocalypse

Dosei

A crazy new SysApoc LitRPG for fans of Dungeon Crawler Carl and 100th Run, but with the insanity set to max. The whole world has gone mad, so it's a good thing that Gambit is already insane. Locked away in a padded room, Gambit watches as the world goes to hell. Blood rains from the sky. Screams echo through the city. Monsters tear through reality. The world transforms overnight into the GREAT GAME, an apocalyptic battleground where monsters hunt, dungeons materialize, and the System destroys everything humanity once knew. All for the entertainment of the unseen audience. Armed with nothing but his fists, Panda the talking plushie, and a glitched character Class that shouldn't exist, Gambit fights his way out of the asylum. But his existence triggers alerts across the GREAT GAME, drawing the attention of its agents who hunt players that don't follow their rules. As civilization burns, Gambit battles both his personal demons and the literal ones stalking the streets. In a world where insanity transforms humans into the very monsters they fear, Gambit's fractured mind becomes his deadliest weapon. What the orchestrators get is Gambit, the glitch they never saw coming. Book 2 continues the hunt for Mayor Sullivan after the Serenity Park Mall massacre, with Gambit's powers growing stronger via a new Benefactor while the Great Game's orchestrators, agencies, and the Adjudicator actively scheme to eliminate him for breaking the Game's balance.

Progression: Explicit central LitRPG System Apocalypse progression where advancement is quantified and drives every arc. The GREAT GAME is a System that apocalyptically transforms Earth overnight into a battleground with monsters, dungeons, and agency-orchestrated entertainment. Power is measured via glitched character Classes (Gambit's shouldn't exist), levels, stats, skills, and Agency/Benefactor patron progression. Gambit's Class is flagged as a glitch by the System, triggering alerts and hunts by the Great Game's agents (Adjudicator, Agencies, orchestrators) tasked with eliminating rule-breakers. Progression gates on: (1) Class levels and skill acquisition through combat and dungeons (Serenity Park Mall dungeon-scale fight in Book 2), (2) Benefactor-granted boons and evolving powers that grow stronger by the day, (3) System-tier escalation where insanity itself becomes a weapon — humans who succumb to madness transform into literal monsters, making Gambit's fractured psyche a measurable combat stat, and (4) dungeon/materialization loops and Great Game balance-breaking milestones that draw higher-tier hunters. Reviews and synopsis confirm 'litRPG System Apocalypse' and 'glitched character Class' as core, with Goodreads tagging LitRPG + Progression Fantasy; Book 2 explicitly notes powers growing stronger and Adjudicator trying to prevent Game balance break, proving structured advancement central.
