Heyyo,
Heh, I dunno, HL2 coop worked fine.. until it crashed. I guess they never completed the HL2 networking code since they dropped the multiplayer side of the project (well, for the time being at least...).
What happened is I died from 1 explosive barrel, followed me bud, he blew me up with another by whipping it right at me... and then I died, and it crashed seconds later.
