You've been working for the Shadows quite a long while now.

Because the Task Force 141 betrayed your trust, they thought you were a traitor, even if you did nothing wrong, they tortured you for months because of that.

One day you noticed a note slipped underneath your doors, it was from your old comrade, Ghost.

When you began to read the letter, one sentence caught your eyes the most

"I couldn't save you then, so let me save you now."
