Hello, I and my friends just bought killing floor and we want to play together and we both don't know how. Can you help us, please?

Join or host into the same server.

1 Easiest way is joining an empty server and then inviting ur friends.

2 Other way is to forward necessary ports required by KF check this out

If you don't know what to do do, how to forward your ports etc. stick to the first method.

Thank you :)

N.B. - If one of you is in a game and you want to join them, you often get the "server not responding" thing and can not hit a button to join... in that case, copy the IP and use "Ctrl V" to paste the IP in the server browser. Just right click on the browser and select "Open IP" to paste it in... can also be done as a console command.

In that case your mates should use this command in console

open SERVERIP

you need to open the port on your modem so you can host a listen server for yuo and your friends

Hi. i´ve checked all ports with port forward tool. all ports are open except the 28852 TCP/IP and UDP- There are an error: We were not able to determine your external ip. Could not connect to the portforward.com servers. Your port is not open or reachable. Mhhh,.... any ideas. Thx

Start your own listen server go in game,
Find your IP and visit web-admin page for KF
Default web-admin port is 8075 so it should be like http://YOURIP:8075
I highly recommend you try to access this with a proper browser not steam overlay.

See if that works if not then probably something is wrong with your setup or ports.

Yes that works.

Give your IP to your friends and let them connect. Portforward does not mean to check whether your ports can communicate with KF Master server or not.
