When you spawn in the players, set each player to a “Team” array. Each time someone takes damage do a for each loop through the array for that team and check if anyone’s health is over 0. If so, the game goes on. Otherwise, show the win screen for the other team.
In the for each loop you’ll probably need to use a boolean you turn on if someone’s health is over 0. Then on the “completed” output check If that boolean was turned on. If it’s true, the game goes on, if not, it’s over.
Good luck!
