Slow Motion/Fast Motion in Any Source Game!
In this tutorial, I'll be showing you how to use the host_timescale command in developer console to make your Source (Valve) game in any speed you want. This can mean slow motion, normal, or even fast motion. Additionally, I will also be telling you how to bind this command to a key so that the speed can be activated only when pressing a certain key. Here are all the commands that were used in the video. Keep in mind that the commands need to be entered one by one, and not all at the same time.
Commands:
sv_cheats 1
alias +slowmo host_timescale 0.2
alias -slowmo host_timescale 1.0
bind z +slowmo
