Hey all, i recently bought this game (yesterday) with a friend to play it in co-op and have some fun, but i found with surprise that the game is unplayable... here is a list of problems i found. 
  
Either my friend or me create the game the same effects appears: 
  
-massive lag and then host crashes. (appcrash, or permanent freeze) 
  
-massive lag and then client get disconnected. 
  
-random bugs sometimes i can connect to a host in find party (yesterday i was able), others simply cant while connecting forever...(today i cant) 
  
Things already tested: 
  
-Upnp on/off 
-DMZ on/off 
-all graphic teaks possible 
-compatibility modes  
  
  
With this i have to say we have played several games already on co-op (hunted, borderlands, resident evil...), our ping is usually between 6ms and 20 (dpends on the game) 
  
No meant to offense but did some1 in the world tested this game in the development? bcoz i dont think this game is nearly in a state to be released. 
  
  
the specs are: 
  
windows 7 x64 
I7 970 
Asus rampage III black edition 
Nv gtx295 
12 Gb corsair dominator GT 2000mhz
