very easy and don't need hamachi, just forward 27015 on your router
then have someone start connecting to your ip, and load hit up "map mp_coop_start" in the console
you'll have to remember what map you got to since you cant really save though (you can see the map with cl_showfps 1) and sometimes it'll glitch out and send you back to the lobby map so you need to load the next in order
you need ports forwarded to host any tcp/ip co-op game... whether your router does this automatically through UPnP or you do it manually it is being done
way longer and you get to know more of the story
What do you need to play it with a friend? (e.g. hamachi)
