Choose your own progression through options such as varied targeting, increased impact vs. increased radius, scatter or burst shots vs. increased size or damage, and many more!

Permanent Unlocks And Upgrades

Earn credits after each run to unlock new ships with different stats and directional module slots to change the way you play.



Credits can also be spent on permanent stacking upgrades for your ship such as increased stats or unique effects like deploying AoE beacons on level up. Each ship comes with it's own ship perk to unlock by completing their unique challenge before you can freely use them on any other ships.

Celestial Modifiers are unlockable difficulty modifiers that provide challenge trade-offs and bonus score multipliers. Unlock them by achieving a victory with all previous unlocked modifiers equipped!
