I got some Prototype Cloaking Device BPCs made up and put them in the invention lab, 2 for Improved Cloaks and 2 for Covert Ops Cloaks. The reason I split them up is that while the profit is higher on the covert ops model, its not shabby on the Improved and they sell faster. I'm all about the immediate gratification.
Well, the two Improved Cloak jobs failed and the two Covert Ops Cloak jobs succeeded meaning that after I make the 6 Manticores (which are in turn waiting for the two Widows) I can build 20 cloaks. Rough estimate of profit is 100-150 million.
