Engine of Chaos Wiki
Engine of Chaos is an upcoming train-survival action roguelike from Bitrot Games, self-published on PC via Steam. As of this writing, the game is confirmed for release sometime in 2026, though it is not yet available and no specific launch date has been announced.
The Premise
You drive an upgradeable armed train through an endless zombie wasteland, mounting weapons and bolting on carriages to plough through the horde -- upgrading between checkpoints to push further into increasingly hostile territory. The journey spans desert, city, and hell environments, testing how far you can go before the horde inevitably overwhelms you.
A Confirmed Weapon Progression
Your engine's turret is confirmed to evolve meaningfully over a run -- starting from a humble machine gun, progressing through twin .50 caliber guns and grenade launchers, all the way up to a triple-barrelled minigun. Discovering devastating combos between your engine upgrades and weapon carriages is confirmed as central to pushing further than previous attempts.
Confirmed Content Scale
The game supports 16 languages at launch and includes Steam Achievements, giving structured goals beyond simply surviving as long as possible.
