How to Play: Spend gold on the cards at the bottom: Economy buildings earn gold, Army and Defenses stop the waves. Tap the Gold Mine to speed it up. Each wave crosses no-man's land to your forward trench, the front-line trench and then the wall; clear waves to earn bonuses and unlock new units. Press Lead to take control of a soldier or gun. Desktop: WASD or arrow keys move, mouse aims, click or Space fires, V or F switches first person, Q/E turn, C charges, G follow me, H hold, Esc lets go. Mobile: drag to scroll, pinch to zoom, stick to move and FIRE to shoot.

Build a toy army fortress and hold the line. Gold mines, farms, mills and a market pay for soldiers, tanks, bazookas, machine guns, mortars, artillery and planes, while waves of tan plastic troops, armoured cars and tanks cross no-man's land toward your trenches and walls. It is an idle tycoon and a fortress defense in one: the battle runs itself, but you can take command of any of your soldiers or man any gun and fight in overhead or first-person view. Earn major upgrades, pick the road reinforcements take, call in the Big Bomb, and push as far as your fort can go.
