Is this your kind of game?
For players who like first-person gunplay, tactical movement and wave-by-wave progression.
Controls at a glance
WASD and mouse on desktop. On a phone in portrait, move with the left stick, drag the right side to aim or hold and drag the fire button to shoot while aiming.
Work the firing lanes
Use the two wide flanks in the Receiving Yard. Containers break enemy sightlines, and a full loop gives you time to reload. Take repair bots out before the heavier enemies they support.
In the Sorting Line, check the arrows on the belts. Cross between them to change sides, and shoot the sorter’s wing attachments to cut down its extra attack lanes.
Read a boss before committing
Leave orange floor markings before the attack lands. The Press exposes its core after a slam. The Magnet Hall boss marks falling scrap, so move away from the landing point and shoot during its recovery.
Keep a coolant route open at the Smelter. A dash gets you out of a marked attack quickly, but its recharge means it pays to save it for a tight spot.
Build your loadout between runs
Completed waves bank coins even if you later lose. Spend them in the workshop to unlock guns and permanent improvements. Keep your service pistol as a backup with unlimited reserve.
Wave break upgrades apply to the current run. Take faster reloads when the magazine is your bottleneck, or select repairs if you took too many hits. Clear all four sites to open Endless.
Progress & backups
Progress and a checkpoint for the next wave are kept in your browser. Export a JSON backup in Settings before changing browser or device.
