Congrats mate... Pulled this off today also, and then got the final blueprint for the M14A. Just about makes up for the time and credits/tokens sunk into the bloody Hayabusa R&D that i'll finish 3 BPs short of the end.

i spent another 130 tokens and an ET right at the end of this MPE just to get into the 500 bracket and win 100 tokens. #facepalm.

Silly question but i only play on ios and can't understand how you can spend credits on double boosters and ETs. Any chance you could explain for this n00b?
