Sorry for the delayed response. So the Verse Device/Creative Device is enabled to run OnBegin() when the Game Starts if it is placed in the map. So I will use that along with the devices themselves which often have a setting for when you want to activate them.
I’m going to try running game start with the devices sooner and treat it like pre-game and prevent the player from starting until I’m ready for it with a barrier and custom countdown or something like that. I think other maps are doing something like that. What are you doing?
