I created a ready-up area for going after biters and I call it “The War Room.”
The War Room Provides the following items: Firearm Magazine, Piercing Rounds Magazine, Uranium Rounds Magazine, Grenade, Explosive Cannon Shell, Explosive Uranium cannon Shell, Artillery Shell, Car, Tank, Solid Fuel, and Coal.
The war room requires the following inputs: Crude Oil, Water, Coal, Copper Plates, Iron Plates, Steel Plates, and Uranium-238.
