Free demo available now
A fast sci-fi survival roguelite about sharp movement, volatile builds, and bosses that demand another run.
15 attack abilities. 28 run upgrades. 39 relics. 10 major bosses. 8 pilots. More than 30 unlockable pilot skins.
Build for the next boss.
Start with a pilot, connect abilities and relics, then turn a fragile idea into something that can survive the screen.
Make a direction
Upgrades connect into a plan that changes how the ship moves and clears space.
Relics change the question
A strong pickup can redirect the rest of the run.
The screen gets louder. Your choices get sharper.
The threat changes from open space to overlapping patterns, then to a boss that exposes every weak choice.
