Cant find a game to play “Prop Hunt” (gmod)

Hello dear friends of Prop Hunt.

I've seen some YouTube videos and find this gameplay extremely funny.

Now I really want to play it, but I can't handle it. I read that there are many Prop Hunt clones and some of them are very bad. Garry's Mod is said to be the best. Now I have bought an extra gmod, but I mainly find DarkRP servers or sandboxes. So where are all these Prop Hunt players!?!?

I activated and follw some Prop Hunt in the gmod SteamWorkshop, but this does not change anything. I already own Half-Life and Half-Life 2 as well as all Couter-Strike parts. Is it necessary to own (install?) additional games? How can I play Prop Hunt like the YouTouber "oldtime101SHORTS" (click me)

Please help… Thanks 🙂
