DET-33
Released 26 October 2026 · PC · Action, Casual, Indie
A bullet-heaven roguelite in the ruins of new London. Take contracts from four warring factions, build a gun that breaks the game, and reach the evac before the city closes over you. 700+ weapons, interlocking build engines, and a fresh map every run.
Story
New London fell in a matter of weeks. An automated weapons system malfunctioned, the reactor breached, and the biochemical cloud that followed mutated everyone who couldn't afford the antidote. Decades later, four factions carve up the ruins, and all of them pay contractors in the one currency that matters: essence, the extract that keeps your own mutation at bay. You're the contractor. Which of their wars you fight is up to you. DET-33 is a bullet-heaven roguelite where the gun is the build. Drop into a procedurally generated district, carve through the horde while your build comes online, kill what the mission demands, and reach the evac before the city closes over you. Every run is a different contract A mission is assigned per run and decides what winning means: some runs end at a climax boss, some at an extraction, some when an objective is done. Eight map events (barrages, feeding frenzies, charged storms) rewrite how a floor plays on top of that. No two maps repeat: every district is generated fresh, from tower blocks to flooded ruins to the open wastes. Build a gun that breaks the game Over 700 guns across 10 categories, upgraded mid-run through gun parts,...
