Buy Engine of Chaos PC key

Engine of Chaos is a top-down action roguelite about driving a heavily armed train through a world overrun by the dead and worse. You outfit its carriages with weapons, keep the engine fueled and moving, and fight through hostile environments. Each run brings a different train loadout and increasingly difficult stretches of track.

Build your train

You can collect and attach over 20 carriage types, each with a different combat role. Equip turrets, flamethrowers, rocket launchers, tesla coils or plasma cannons. Stack flak cannons for crowd control, add fuel carriages for longer journeys, or focus on tesla coils to send lightning arcing between hordes.

Fight across six environments

You battle through scorching deserts, abandoned industrial zones, overgrown forests, ruined cities, alien hive colonies and the depths of hell. Each environment brings new enemy types and threats. Across them, you face over 40 kinds of enemies, including shambling walkers, burrowing horrors, bomber bats, acid spitters, riot shield zombies and towering bone colossi. Learn their patterns or risk being overwhelmed.

Repair and upgrade

At checkpoints, you can repair and refuel the train and upgrade its hull, speed, weapons and ram damage. You can also make individual carriage types deadlier. Upgrade points are limited, and each stretch is harder than the last.

Keep the engine running

If the train runs out of fuel, it stalls; if it stays stopped too long, the run ends. Taking too much damage causes the train to explode in a chain of fireballs from caboose to engine. Procedural enemy waves grow more difficult with distance, as you try to travel farther before the horde catches up.
