How to play Shadow Warrior Co-op / other Multiplayer modes

[Slaya]

Get YANG: http://yang-online.com/shadowwarrior.htm I'd suggest using the LAN method so it can be used with Evolve: http://www.evolvehq.com

This will be the easiest way. (No ports will need to be opened.) ;)

Your buddies can use the Redux or GOG version too!

How Evolve works:

One person creates a Party and the other joins. This creates a virtual lan. Leave the Party open or minimize it before launching the game as closing it will disable the virtual lan.

You can also set the Party to Private which is invite only for your Friends. ;)

Then one person hosts a Lan game and the others join.
