Oh cool,
Take out the elimination and assist scores in the island settings
You can use a player counter, using its zone setting could be more reliable, sets its target to 1, use the on count succeeds event to add the score and end the round.
set it up so it starts disabled, otherwise it will end round and won’t be able to playtest.
For this you could turn it on for public, but I recon a second player counter with 2 or maybe target greater than 1, who’s event, enables the first player counter.
You could also use the on count success event to enable the main player counter and the on count fails event to disable the main player counter. So if only one person is on the server, it doesn’t end the round.
