The game from the ads — except it’s real. Grow your squad through the gates, then hold the line.
Drag, mouse, A / D or ← → to steer. Swipe up / down (W / S, mouse wheel) to squeeze or spread the squad.
Shoot + and − gates to raise their numbers, but they block your bullets, shielding zombies behind them. × and ÷ gates let shots through.
