[quote name='pete5883']It's not much of a bitch at all, unless you've been skipping everything. Only took me about 2 hrs of extra play to fulfill the requirements. You can simply save, get 3rd ending, load, and get the 4th ending.

Yeah, same with me. I didn't find it that much of a bother. There was only one or two missions that were a pain, but for the money, I just sold a bunch of crap I didn't need and easily had enough to buy the weapons I was missing.
If you do decide to do that, just make sure you pick the first option when going for Ending C , then go for Ending D.
Nolan North was Balloon Hitler by the way. (Ah I see I was beaten to the punch.)
