Basket sets up turrets with their own ammo supply, adds rows of steam engines until power runs ahead, starts on walls and turrets made by machines, and meets the first enemies.
Green science is the goal: Basket builds green circuits, an inserter line and four green science assemblers, then runs short of power and adds more steam engines.
Season 2 opens on a new map: burner drills feeding themselves coal, a first belt of iron and copper, steam power from a small lake, and the first red science made by machines.
