how many co-op missions are there and what are there names?

[mattlewis]

my clan has the most fun running through these segments in co-op. just curious how many there are and if there will be updates or dlc featuring new ones. currently we only can play 2.

There are seven in total.

And I'm assuming they'll eventually add more down the road. I just don't know when.

Here's a link to the wiki. As you level up you will unlock these maps. They are a great way to level up weapons and XP. I have all of these maps unlocked, and hopefully there are more to unlock, or will be via DLC.
