Black Op's - Zombie Achievements

Just wondering if anyone else like myself needs the Zombie achievements for Black Op's; this is a game mode that i never really played so understanding what has to be done just will not sink in for me!

If anyone else needs these or indeed if you have the achievements and fancies lending a hand to farm all the remaining gamerscore then please post and we can arrange a few gaming sessions!

Thanks for reading!

i need them just short on time as trying to finish red dead redemption before i have to give it back.

I need the one for using all the weaopns on the walls or something.. dunno if theres anything else
I dont have any of the map packs that came with the limited edition, just the ones that came on the disk..
If you need me give us a shout when you get a game arranged..
