I've added you to our latest RS:V2 boosting list. And I'm more than happy to help you with co-op on realistic. It's been a while so I'll be a little rusty to start, but it'll come back I'm sure... just like riding a bike.
But do you mind helping us out first? Assuming of course that we get a good group of 6+ to boost those last few chievos? Let me know.
I saw your message on the achievement trading thread for RE5 i replied giving you some explanations for some of the ones you need but i also am offering to help you with the war hero achievement if i have time and if your willing to have inf ammo turned on (some people dont like having it on for some reason )
