This milestone quest requires you to revive teammates. When you are playing duos, trios or squads you will get an opportunity to revive a fallen teammate before they are eliminated from the game for good.

If a teammate goes down you will need to get to them as soon as possible otherwise the enemy players might finish them off. Even if they decide not to, a downed player will only last for 60.

If you are playing with friends you can grind this out by asking them to down themselves by damaging themselves. Building a ramp and jumping off works very well!
