This isn't cumulative between all your different characters, it must be done with one character.

Just join a game online or local and keep playing. Or just plug a new controller.

I think you can do all the co-op achievements with 2 controllers.

Just use two controllers, leave the one you're not hunting for achievements on, and go play,

Is there any way to check how many co-op missions your characters have done? I know this is cumulitive but it I would like to know how many I need to get on my main character.

Anyone who wants to do some co-op, especially Crawmerax, but it doesn't have to be DLC anyway add me: mcNizza I'd also like some modded weapons and a shield if anyone has some.

Plugging in a dummy controller does work pretty well I must say.

yeah a dummy controller is the way forward, easiest to just start a split screen game with a new level one character as host and just play through the first 15 mission as they will be 'trivial' by this point.

i found you only need to 'turn in' while in the multi player, already had a load of missions ready to complete so there wasn't much more to do.

Play solo, get bunch of quests done, turn them in, while in splitscreen. It easier that way, since more players = tougher enemies
