Hi,

I bought EE2 and wanted to play lan with hamachi with a friend. Bute we needed to enter a CD Code. But we didnt get one!! i am really angry and dont know what to do because LAN should work god dammit!!
pls help me

Install Unofficial Patch 1.5 from: https://ee2.eu/patch
And then play Multiplayer using the lobby: https://www.youtube.com/watch?v=uhZ7ESYLLSo

I agree that Gog should give a CD-KEY to everyone who bought the game, but well... they have an information on website:
Multiplayer notice: The game's official multiplayer servers have been taken offline and the only multiplayer option available is LAN. Multiplayer mode is available after registering your unique CD-key for the game. For details see: Support.
