I am very nearly done with SP, just a couple of missions to go, which I expect I'll finish today, so I'm good to play the MP at any time over the next couple of days.
I need all the MP achievements and 3 combat ones.
My one problem at the moment is that my xbox Live headset is buggered, so I won't be able to chat, however I'm always got steam on the go for written chat, and I can Skype as well if that would make things easier.
If anyone wants to do these over the next couple of days send me a message over live to GT: Grumftheld and let me know if you can steam chat/skype. Please send a message though and not just a random Friend Request as I delete them out of hand when they don't have a message attached.
