Coop Campaign

You can now enjoy the single-player campaign together with one or more friends in a brand new coop mode.

If you start Zero-K from steam, you will find "Invite Friends" button in several places.

Coop works in these places:

• single player campaign (you will share same commander)
• single player skirmish (you will have own commander)
• replays (you can watch replay together and chat)

Coop mode is player hosted, meaning it does not need any game servers yet it will work with any network configuration, even with closed ports etc. If you have high pings but want to play with local friends, you will love it.
This feature also gives us some resilience in case of Zero-K server failure, it does not need any existing Zero-K infrastructure to work.

If you wish to play campaign with friends now, ask in forum, or contact GoogleFrog or Licho and we will give you a free steam key :-)

Does this use NAT punchthrough? If it does, I can't run it =(

forcegod, it tries to do hole punching through NAT, if it fails it uses steam CDN servers for relay.

Can i have two keys?

Man, huge features just keep on rolling out. Who is doing all this work!?

Originally it was implemented by using steam P2P to exchange IP/port/game information and then perform NAT traversal/hole punching using google STUN server to open ports for spring.

Later it was rewritten so that wrapper hosts one or more mini proxy servers, spring connects to wrapper and wrapper does the packet relay over steam P2P networking services, which have fallbacks to use server based relay.

So the beauty is, that spring does not even know to what it is connecting, it connects to "localhost" and gets data from localhost.. wrapper manages the list of clients and does the needed routing etc..

Thats why it should work under any network configuration (which allows steam to run).

GoogleFrog made it so that you can exchange saves via modoptions between players in coop mode and tweaked editor functions to sync camera in custscenes etc.
After you play with a friend you can continue campaign from "his" save.

So technically it is quite well implemented SP coop as other games go.

I'd like two keys as well if possible. Thanks in advance!
