Got to 42 last night with 2 friends on Kino. Would have went further if the game didn't lag so damn much =\ All 3 played legit, I was the last one alive. When we hit the lobby again after the end of the game, they both updated for rounds survived, but I didn't. All 3 high scores updated. Unfortunately this is NOT the first time this has happened to me, I can recall at least a dozen others, with all different scenarios. I posted everything me, and friends tried to make sure your game would stick on the leader board but nothing seems to work. It's just "hit and miss" which leads us all to believe it is poor coding on 3arcs end.
With all that said, I'm not touching zombies again. This game fails on so many levels, cant believe I paid $60 for such an incomplete, buggy game.
