So I did the whole campaign in less than 5 hours, which for me, translates into a ver small game since I usually dwell on games and I like to take scenic routes and what have you.
At any case, I did the whole campaign starting at the easiest option (can't never remember what it is). When I was done, the Campaign was at 50% and it baffled me a bit but glad on the other hand as I suspected something else was coming that I had previously missed.
I was kind of upset when someone mentioned that I had to do the campaign again in Veteran (hardest level) to finish off and get to 100% but, the game is not half bad so I decide to try my luck with it. Boy, do you really die on this level, suffice to say, I am done but, to my dismay, the thing now reads 86% and I don't know what else to do.
The only thing left there is a Museum thing but I doubt that is part of the Campaign... anybody else done with it that can lend a hand?
