I do believe you need either a level 3 assembler or an oil refinery, as you need oil -> red circuits -> speed modules -> level 3 assembler and you need a level 3 assembler to make an oil refinery as it has 5 components.vaderciya wrote:I'm also in favor of a "no crafting" chiev, where you start with a basic assembler, 2 boilers, 2 inserters, 1 steam engine, 1 burner drill, 1 stone furnace, and an iron pickax(and you can't craft anything in your pocket).
Similarly you need a level 2 assembler to make a level 2 assembler as it has 3 components.
