I run a regular coop server Psych. I'd be pretty interested in discussing the needed setup for this to make it a voteable section on my server. Looks like fun.
Hey gopo, nice to see you being interested, although I'm not sure if that kind of gameplay would suit you (not for me to decide of course).
I'm not sure if you can make it votable. INF is as total conversion as TC can be, so it requires a server to exclusively run INF with Unreal/UT maps. But I don't know for sure however.
As for setting up a server. You need the
INF Coop files. Additional set-up information is
here. The Psytex mod is advisable, as it is a facelift to the aged game and all servers use it, but to make it easy to bring INF up to date it is best to use the
Infiltration 2.9 CE 2011 installer.
Setting up a server might be tricky, so you can ask for help either here, or on the
INF co-op forums. Though, these are quite inactive and it may take some time and perhaps several bumbs to get some answers (which is sad).
