Since i don´t read anything either here or in the gearbox-forum regarding a patch for these horrid multiplayer lags (360) i assume Gearbox has already abandoned this game.
Lesson learned that was the last game i bought from this developer.

I played half on a multiplayer match and left, didn't like it at all. But that didn't stop me from enjoying this game. I have already beat it at least 10 times and I think there is like one mission I have to do on Authentic to fully beat the game. I didn't really expect a good multiplayer so I never got my hopes up so I wasn't disappointed.
