History of Back in the Fight

Back in the Fight is a Crucible triumph in Dominion. The game text reads: "Revive all teammates as the last Guardian standing." It tracks "Medals earned".

How to complete

The wording and the "Medals earned" objective suggest it counts a revive medal. The closest known medal is From the Brink ("Revive an ally as the last Guardian standing on your team"), which may be the one counted.

General tips: stay alive near a downed teammate, and revive them before the enemy team reaches you, since a revive while you are the last teammate standing keeps your team in the round.
