Description
You never move. Your artillery fires itself, and between rounds you dig through 180 upgrades to make it stronger. Beat the 25-round campaign, or survive as long as you can in Endless mode.
You never move. Your artillery fires itself while the enemies walk towards you.
- 85 abilities across 8 elements: bolts, orbitals, beams, turrets, mines and minions
- A 97-node passive tree that only shows you what you can reach next
- 18 keystones that break a rule instead of adding a number
- 14 status effects that stack, spread and set each other off
- Five bosses, each with their own attacks and phases
- Ten difficulty tiers where enemies hit harder rather than just soaking more
- A damage meter that shows which ability is actually carrying your build
- Keep the Stardust you earned when you die, and spend it on the passive tree before the next run
