I bought this game with the sole intention of playing online and have struggled to do so since day 1.
The game constantly freezes your playstation and the only way that you are able to play again is to turn off the playstation and turn it back on again.
Joining multi-person parties is frustrating because you can never seem to find a game. Even though the lobby is full you get the message "waiting to balance teams" When you get tired of waiting and try to find another game, you have to reassemble your party as if you were not playing together.
When you do finally get into a game, you are almost better off waiting in the lobby. The hit detection is very poor and the games frame rate is choppy.
I had high hopes for this game but again am extremely let down.
Extremely poor execution on behalf of Treyarch. Will not buy another game made by them.
