I actually have done this on CS:GO, I approved this game over there. HOWEVER there are some differences so here is how the game works for me.
>CTs hide, no guns allowed.
Ts search and kill, CTs may not move, but may knife any T coming close enough to them.
There is Last CT, when triggered the LCT may move freely and massacre the Prison scum.
There is no LR, stop being a pussy and go hunt down those CTs.
Played as a warday/freeday, must wait 3 rounds between.
Since I had no name to call it, I just settled on reverse hide and seek.
