I'm not really sure if any of you PS3 gamers experience this but after playing a few rounds/maps on Black Ops II Multiplayer, it would totally freeze my whole PS3 system. This has been happening since yesterday after the update and I'm not sure what it means... I don't know whether it's a bug of the game itself or my actual PS3 system. But playing Zombies online works perfectly fine with no lag or freezing.
If anyone has the same experience post here and see if Treyarch has any suggestions. Thank you.
