@PerniciousPea I've had the game freeze more lately also. I've also been getting kicked from the server more these days, sometimes with just a few seconds left in the game.
The hacking, with players playing as bosses or spawning endless AIs is also still a problem. Yesterday there were four Iron Citrons playing as Zombies. I was a zombie but they seemed to be invincible. Just weird and to me pointless. Sometimes the hacking is harmless; sometimes it makes the games unplayable. I've been seeing a lot more cheating the last few weeks. Recently a player had 119 vanquishes - I've never seen that before even with players who cheat. Yesterday a player had 45 vanquishes at the end of the first objective. At that rate he would have had over 200 vanquishes for the game if it continued. It's always a Super Brainz but not necessarily the same player. That said (and said over and over and over to deaf ears at EA) , I've also had some of the best games I've played in a long time - evenly balanced chaotic nail biters that went the distance. Too bad those are the exception.
