Same for the co-op campaign.
LAG. So much so that co-op on this game is pretty much unplayable. Doesn’t matter if I (or those that I play with) have an open NAT, high speed connection and all the bandwidth in the world it will still lag. Reach had the same problem.
When looking into it it seems that it is a problem with the way the game handles the AI and syncronisation between all players. How is this an issue? The premier (or they hope so) fps game on Xbox that has co-op that is fundemetally broken.
Gears of War 1,2 and 3 has AI and co-op that works perfectly. Same for Borderlands 1 and 2. Left 4 Dead 1 and 2. I could go on…
Such a shame that it does not work right.
