Drop balls down a plinko board to recruit your squad, arrange them on a hex grid, and send them auto-battling up a 25-floor tower. Stack augments into explosive synergies, but every unit that falls is gone for good.
Team up for explosive co-op, take on the campaign solo, or challenge friends in Arena PvP. Clear 20 levels of enemies and spawners, find upgrades and plan your escape before the bombs go off. Play with up to four in campaign or eight in continuous Arena battles.
