Lots of people are waiting for a patch, I use R4 WOOD 1.15, can't climb ladders and don't have zombie mode... Just sit down and wait, it'll be released this week, I'm sure!
I agree with you on the first gun (M14). That M14 sounds really weird. When you get the second one, with the scope, it sounds way better! More like "BOOM"
I got Black Ops for my DS, game works fine on R4 WOOD 1.15. Only thing is, which is AP; can't climb ladders, can't play zombies (don't see it in the menu). Any idea how to fix that?
