I have Doom3 Open Coop 1.1Alpha and 2.0Alpha. The server side works just fine. BUT - Both require files to be installed on the client machine. I do not know what these files are. The readme file does not contain installation instructions or comments on these files.
The developers - d3opencoop -
Opencoop - Doom3 Mod have not maintained the forum or FAQ section of their website to provide this information.
If anyone knows what files are needed for this Coop for either PC or Mac machines or has a copy of the installation instructions. Please inform me.
Thank you.
