A recently found Fortnite exploit allows you to revive your allies instantly. In most battle royale games, players have "two lives' so to speak. When your health, shields, or armor is broken, you go into a knocked phase. This allows your friends the opportunity to pick you up to keep playing.
To punish you, the feat takes some time and gives opportunities for enemies to push or finish off the squad. That's why instantly picking up teammates is too powerful.
The trick was shared by YouTuber OrangeGuy.
Fortnite Exploit Allows You to Revive Allies Instantly
To use the exploit, teammates need to equip a pet back-bling. When reviving a downed ally, aim your crosshair above their back-bling. As you line it up, the revive prompt should disappear and then reappear when you move the cursor. This is the exploit, simply tap the revive button as the prompt disappears and you will instantly revive your teammate.
Since the exploit is gaining traction online, it won't be long before Epic Games fixes the bug.
