I saw an solution for this on another post that I didn’t understand how to do but couldn’t ask them to clarify since it had been marked as resolved. BTW it’s a battle royale game.
So @WhereIsMyHat, make an enclosed space. Like one square floor. Make that the spawn area ONLY FOR THE NON one player team people.
Mini Guide
Put a zone there and wire it to a counter, incrementing it. Make the counter’s target zero. Now, make a lifecycle with Player Knocked out. Or something. Wire the lifecycle to the counter. Then, when only one person is left(The one player team), the game will end.
