You will need the console commands to enter in these commands: DemoRec (Starts the demo recording) DemoPlay (Plays the demo, as long as you have the file name infront of it) (Example: DemoPlay KFMainMenu-12345678) DemoStop (Stops the demo recording) ShowHud (Shows the hud)

To play the demo, you need to find out the file name. To find the file name, you need to go to this file path: C:\Users\USERNAME\Documents\My games\KillingFloor2\KFGame\Demos

Be aware that starting recording in multiplayer will cause a game crash unless you log in as admin on the server and do the command "admin DemoRec" (or "DemoRec" if you login the webadmin and use the command in the console there). The file doesn't store in your client-side when recording from multiplayer, but in the server-side instead. The server's path is KF2Server/KFGame/Demo. You do DemoPlay from ingame console. The demo you recorded in Solo will automaticly end after a map switch. When you play the demo, it will take some few seconds to load the demo. This feature is very useful for recording endless speedruns due to its very low file size compared to recording with recording softwares like OBS, Shadow Play, XSplit & Fraps. Demos are recordings that are a lot more interactive then other methods of recording with very low file size without sacrificing video quality. It adds a bot with the name "DemoRecSpectator" which does not effect the player count on server browser, but does pop up in webadmin's playerlist. This feature has been a feature ever since the arena shooters like Unreal Tournament & Quake. The hud is off by default on demos, so if you want to see the hud, use "ShowHud" Command.

Fauxy found this out btw.
