Making different scenarios to spice up CSGO

What kind of Scenarios we have already done:

-R8 Revolver cowboy stand off
(both CT and T sides rstand in line facing each other and when the timer in the round reaches a certain point, both sides shoot till one side is completely destroyed.)

-Civil war muscket firing squad
(
-Knife only (pretty simple enough)

-Shotguns (Pumps only and either stand off only ((for now)) )

-NA Nades
