As it says on the tin!
there are numerous DLC only achievements I’ve not even had the CHANCE to get because of the lack of players in these playlists.
I’ve got all DLC, and if anyone out there wants to party up for the infection achievement or any others I’d like to hear from you please.
I play Reach most nights and aren’t exactly crap 
so hit me up on this account!
I’m UK based and usually play between from about 5pm (I work from home so I log on as soon as my mac goes off 
)
If you request me on XBL just let me know its to do with this post.
Cheers,
Rich
