I have been experiencing multiple problems. Instead of actually freezing, my PS3 will shut itself off and the red light will blink. It does this in every mode (zombie, campaign, multiplayer) and ranges from 10-120 minutes of game play before the involuntary system shut down. It starts right back up after it does turn off and completes its routine check on the hdd. It appears to happen when there is a heavy populated battle or a very detailed setting in the game. I've also lost the ability to play multiplayer due to not being able to connect to the servers. I've experienced the lag (in the 10 min. of actually playing it), which in contrast to the system shut down, is very low on the totem pole list of priorities. Although some issues may present themselves on release day, I can't help but feel this was a poorly made game and I would not recommend it to others.
