I have been trying to play this game with my friend but it is not working. We both have the GOG and steam versions, all DLC's installed. We set the online options to LAN, used Nemirtingas Galaxy Emulator, restarted windows, used Radmin VPN, but no matter what we did, whenever one of us tries to join the game it says "Unable to join the game, the game you have tried to join is no longer available!" I searched this topic at cs.rin.ru and the internet but didn't get any solid answer. People here were saying how they were using VPN with the GOG version perfectly for coop but I can't seem to get it working. I stayed up all night trying to make LAN/coop work for this game but it does not work! This is what I did:
1st try
1) Extract the game (CSF)
2) Applied Goldberg Emu (normal one)
3) Configured steam.settings folder for DLC's, added steam_appid.txt, generated steam interferences from the original steam_api64
4) Used steamless on the game exe
5) Launched the game, went into matchmaking and both me and my friend tried to join each other (not at the same time)
Result: Unable to join the game, the game you have tried to join is no longer available
2nd try:
1) Extract the game (CSF)
2) Applied Goldberg Emu (experimental one)
3) Configured steam.settings folder for DLC's, added steam_appid.txt, generated steam interferences from the original steam_api64
4) Used steamless on the game exe
5) Applied Nemirtingas Epic Emulator (configured it, just changed name to match goldberg emu)
6) Launched the game, went into matchmaking and both me and my friend tried to join each other (not at the same time)
Result: Unable to join the game, the game you have tried to join is no longer available
3rd try:
1) Extract the game (CSF)
2) Applied Goldberg Emu (experimental one)
3) Configured steam.settings folder for DLC's, added steam_appid.txt, generated steam interferences from the original steam_api64, added disable_lan_only.txt everywhere
4) Used steamless on the game exe
5) Applied Nemirtingas Epic Emulator (configured it, just changed name to match goldberg emu)
6) Launched the game, went into matchmaking and both me and my friend tried to join each other (not at the same time)
Result: Unable to join the game, the game you have tried to join is no longer available
At this point I give up, mind you this all is just for the steam version, I first started with trying to make the GOG one work. I spent all night scouring the internet and it turns out many other people are experiencing this issue, have been for years actually. Some suggested it was because of dynamic ip's, some said it was because of NAT type, some said it was because of "out of sync" date and time zone settings in windows, but none of those were my issues. Ip was not a problem because both me and my friend could see each other in the lobby, for most people the issue was that they could not even see each other. I tried all the other claimed fixes but none of them worked. So either the newer game updates broke LAN, or I am screwing up somewhere in the configuration process. Please help me fix this, thanks in advance!
