I have something to I want to be added to the game, better workerbots the crafting recipe could be something like this
Number of metal gear(s) Number of metal plate(s) Number of metal rod(s) = Expert Bot
EDIT:One thing is never enough, so I got more. one thing is you need a better Worker assembler (maybe call it a warehouse or a factory) to craft these new bots, another thing is you could upgrade your Bot at the Worker assembler and not need a warehouse or factory (whichever one you choose to name this possible structure.) and it will cost a lot
