The foundry gate is open and the furnace-born are pouring through. Keep moving, shred them, and feed on what they drop. Executes give health, the saw gives ammo, and burning foes shed armor. Every fifth wave a boss comes through the gate.
Execute · FHurt a foe until it glows orange and staggers, then finish it up close for health.
Saw · CCut a foe in half for a burst of ammo. Fuel pips refill slowly.
Ignite · QTorch everything in front of you. Hit burning foes to knock armor loose.
