War, a game mode from ARMA 3 BR that has a deathmatch style where players kill each other for 30 minutes (if you die, you respawn back in with a parachute) and then at the end once the blue zone locks in, you can't respawn anymore. After the blue zone locks, it will end normally in a BR ending with the circles, bombing runs and air drops.
PLAYERUNKNOWN stated in interviews that this is a game mode wanted to implement into PUBG [1][2][3].
