I just finished Portal 2 Coop with a friend and now we intend to go back to the beginnings of the Half Life Universe. We would like to play trough
Half Life Source and Half Life 2 cooperatively but we are not sure if there are well working coop mods out there.
I found this one for Half Life Source: http://www.hlportal.de/?site=files&do=showfile&file_id=325
I couldn't check it out myself since I don't own HL Source, yet, so it would be cool if you could share your experiences with that mod (or any other working
mod) with the community.
There is this Mod called Synergy for Half Life 2 which seems to be a little more advanced but I still have to check that out as well: http://synergymod.net/Media
Anyway, thanks for your comments/thoughts/advises
