Suprised at the amount of people that don't know about the beta. There's an opt in beta for Killing Floor 2 currently, I must say its the best version of the game there has ever been, game looks so much better and is a lot more challenging especially on Suicidal/Hell on Earth due to new AI, alpha zeds and scrakes can come for your ass at wave 2! On top of that new map and new SWAT perk.

To opt in go to Library>KF2>Properties>betas and then get on!

Happy zed killing
