I have noticed that collecting nano crystals doesn't sums up through levels... I had like 500 of them and now I'm in Dead Man Walking lvl and I have... -100 nano crystals. wtf? How I'm supposed to buy upgrade for 800 or 1200 nano crystlas when they don't sums up? fix that please.
errr... I think I'll wait for patch (again, like ME2, COD: BO and another games that was released lately)... devs really should be ashamed of themselves. They aren't able to release fully working product these days '-.-
