You were on a mission to Shadow Moses Island, your objective is to kill the leader of the Genome Soldiers, Liquid Snake

When you reached a long hallway you were shot in the neck with a tranquilizer by a sniper

you woke up stripped to your underwear and tied to a wall

In front of you was Liquid Snake and Sniper Wolf, she's the one who shot you

Liquid Snake:"I'll leave the interrogation to you Wolf, Me and Ocelot have business to take care of"

Sniper Wolf smirked at you as Liquid Snake left.
