Just to add a little to what's posted above. This can also be unlocked in private Game Labs. The host can set up 2 sets of forced abilities allowing you to go through 4 abilities and 2 ranged per round of game labs. To switch from set 1 to set 2 you will have to be killed and then use the D pad to toggle to the other set.
If you've got one person with all of the abilities and weapons then they can host and share them with everyone else.
If it's just you and a buddy you can plan which abilities and weapons you're each going to buy (since we all know having enough currency can be a little bit of a problem) and then you can take turns hosting and sharing what you each have.
Anywho, hope this helps some of you. I was lucky enough to have a friend that had purchased all of the abilities and weapons and we popped this out in no time.
