Your hangar is the last thing standing. Wave after wave, alien ships come for it, and every one of them is built from destructible pixels. Shoot an engine off and the ship tips, spins and crashes, and its wreck explodes on whatever it lands on. Between waves, draft upgrade cards, spend your silver on your ship and your base, and see how long you can hold.

Draft your run

After each wave you pick one card from a hand of three. Build around fire, frost, acid or volt and watch the elements react, choose between forks that pull your run two ways, or take a cursed card that pays big and costs you.
