(adsbygoogle = window.adsbygoogle || []).push({}); ok so if some one completes the ghame on the hardest difficulty, then would creating a co op game on the hardest difficulty on the last level then inviting their mate to it and then completing the level, (im sure it could possible work like zombie apocalypse) it will unlock a few trophies:

complete campaign in co op
complete campaign on morbid
complete mission 10 (i think)

then you can just rush the campaign on braindead for the other trophies.


if anyone has completed it on morbid difficulty then hit me up with a friend request and we'll get to testing this theory and if it works we can help others out

update each person must have the level unlocked

Wont work, because both of you have to be at the same point in the game, and mission select doesn't give you trophies!
