Hello Guys, I can't play COD MW3 online, when I select multiplayer a black screen appear and then I go back to the XMB, I tried thousand times and still the same problem, please help me ! I'm on DEX ps3
Have you tried checking for a fix from opoisso893 (aka backport893), tho it's an older game so it might be harder to find one if a fix is even necessary.
I wish I had another game suggestion for ya but I haven't had a PS3 for several years myself... back when I did I played Untold Legends: Dark Kingdom though.
