Launch your puck through waves of machines. Bounces add damage, and survivors advance after every shot. Stop them before they reach the reactor.
Choose upgrades between waves: piercing hits, explosions, lightning and more.
Campaign: 12 levels, eight waves each. Beat a level to unlock the next.
Daily: the same challenge for everyone, with all parts available. A new challenge at midnight UTC.
Endless: keep your build going for as long as you can.
Online leaderboards for every Campaign level, each Daily challenge and Endless. Unlockable parts, personal records, 13 achievements and a short playable tutorial.
