Well, I'm not sure of the command, but first I'll tell you about a thing in a map, if you know the map ZM_SPACE_SURVIVAL, there are these green smoke dualies, and i'd like to know, what is this command and a way so everybody has it. If you don't know the map I'll explain the question just down there.
What is the command or whatever can be the Brush/entity that makes someone goes fast and who can push people and when you try to go back, it just makes you go slower. I'm not sure if you understood, but I wanna make a kind of race map with that thing.
PS: I can't decompile the map, it's like protected from it.
