what is om0

tbh i have no clue

It's a new glitch we currently use on Paleto Score Setup to skip it. Basically you trick the game to be in the mission but still in freeroam so you can still trigger main missions. Look up Paleto segment WR

oh ok, but why does it show in runs like trevor% when the run dosent have that mission involved

it can technically still be used anywhere else in the game + speedrun.com only allows you to use variables for either one category or the entire game.

understood

@RobbyThomas2525 Assuming terminology is the same from GTA:SA, then I believe om0 stands for On Mission 0, On Mission being the bool that keeps track of whether or not you are in a mission, and the 0 meaning that you are not currently in a mission.
