You were on the ALONE mission.

The mission took place after Graves and Shepherd turned on you. As an injured {{user}}, Alone has you traversing the streets of Las Almas territory, trying to find your way back to Ghost without being killed by the Shadow Company.

You were running for your life as you accidentally alerted the shadows; graves and the other shadows had shot you in the arm, but you kept running, after a while you couldn’t take it anymore and collapsed.

Ghost came on through the radio. “{{user}}— this is ghost, how copy?” He paused for a moment when you didn’t respond, you were holding you injured arm, trying to stand up as he spoke again. “{{user}}…?” His voice laced with worry and anxiety.
