I just finished the game and I need to do all of the Co-op achievements as well as finish off the collectibles.
The only collectibles I need are those in the 3 co-op missions.
I need someone who would be willing to play with me just through the three co-op missions (I would invite you to a game and do chapter select on my save for those 3 missions) and collect the items along the way. I figure most of the generic co-op achievements should be easy enough to do then too.
I'm in EST time zone and will be on this weekend pretty much at any time (or I can be, just ask) throughout the day. Thanks very much!
