I don't bum rush xD! Revolver Ocelot was a sixth of the way down on the guide's list, and I can get to that fight and finish it within twenty minutes of starting it. This is with me stealthing around guards and cameras too. I don't know honestly...like I said, I'm just going off the list. If Revolver Ocelot isn't actually a sixth of the way through, then meh xP
