Who the hell…?

The main subject is a player in a first-person shooter game, viewed from a top-down perspective, who is holding a knife and moving along a narrow ledge. The player approaches an enemy character, who is standing on a higher platform, and then the view abruptly shifts to a close-up of the enemy's face, which is obscured by a patterned head covering and sunglasses. The setting is an outdoor urban environment with concrete structures and buildings.
