Okey so about 50% of MPGH guys know that Crysis 2 got leaked some time ago. Here's tutorial how to get multiplayer working in this beta.
1. Download crysis 2 beta (just google it / search from torrent sites)
2. Download and install tunngle and sign in there
3. Place these lines in system.cfg file
4. Join one of Crysis 2 lobbys in tunngle (Crysis 2, Crysis 2 etc. etc.)
g_gamespy_loginUI = 0
net_lanbrowser = 1
net_initLobbyServiceToLan = 1
sv_gs_report = 0
sv_gs_trackstats = 0
5. Launch crysis 2 (bin32 version), go multiplayer and enjoy.
Hope this helped those who didnt know yet how to play multiplayer (Press "Thanks")
PS: Anyone knows command/line to change rank level? I know there is one, but cant find it. Post it please, if you do!
