Also want to add a need for online matchmaking for Guerilla and Campaign co-op. I was really looking forward to Guerilla mode and it's disappointing I can't get the full experience unless I coordinate 3 other friends who have to be online and wanting to play this mode at the same time as me. As someone mentioned earlier, a lot of my friends playing this game are on different time zones and it's not that easy to get 4 people online playing and starting at the same time as myself. If I am playing early on a Saturday morning, it's literally impossible to play Guerilla mode unless I start trolling in MP lobbies for people to play with or posting on forums to get friend invites so I can get a good 4 player match. Most of the time, I will never have 4 friends online at the same time which makes this mode non-existent for me and that is a shame.
I guess I don't understand all the complexitity that goes into this, but right now the game allows play with 4 different people online who can be in 4 different locations on 4 different Xbox's which seems like the bulk of the work. We are just asking to allow functionality to place me in a room of 3 other random people instead of having to do it with 3 friends.
