I've recently dusted off an old Dell P4 desktop unit and rigged it up to my 52" LCD. I mainly did this as I'm fed up with my PS3 not playing certain file formats.
Anyway my little Bro and I both have HL2 running pretty nicely and I've briefly looked into some of the mods that are available, either via Steam or other random websites.
What I would really love is a mod that allows two people to play through the single player campaign. I don't know if such a thing exists (mainly because I don't see how the scripted 'story' moments would work) but I have seen mods that allegedly do this.
Synergy is one that I am currently downloading. http://synergymod.net/About
I'm just curious if anyone here has had this working and know if it's stable etc.
Also, please recommend any other coop-centric mods that are fun (and ideally free). Am downloading Zombie Panic at the moment. Figured you couldn't go wrong with that ;p
Any advice appreciated!
