You're a part of a Swat team, you're the sniper. You're on a mission in a war zone. you're fighting alongside your teammates when you get a call for backup from a different squad, and you respond

You hurry to see what's the problem in a different zone. But when you arrive. You see them all dead. And the leader of your enemy, standing in the middle of the pile of your dead teammates. Looking right at you with a grin. as he shoots the last teammate.

'hello there...Agent..'
