SINGLE-PLAYER SKIRMISH VS THE AI
IRONFALL
Harvest crystal, raise an army, and level the red Command Center before yours falls.
- Select — left-click or drag a box. Double-click grabs every unit of that type on screen.
- Order — right-click ground to move, a crystal to harvest, an enemy to attack.
- Train — select your HQ: Workers (Q), Soldiers (W), Tanks (E); research Weapons (R) and Armor (T). Right-click ground to set a rally point.
- Build — select workers: Depot (Q) raises supply and is a drop-off point; Turret (W) guards a choke.
- Camera — arrow keys, screen edge, or middle-drag. Wheel zooms. Click the minimap to jump.
Workers carry 10 crystal per trip. Soldiers counter infantry, tanks break buildings. Waves hit harder over time — don't wait.
