In the video, a person is playing a first-person shooter game. The player is holding a gun and is shooting at enemies. The gun has a scope attached to it, which the player uses to aim at the enemies. The game's HUD (Heads-Up Display) is visible, showing the player's health, ammo, and other game-related information. The player successfully hits and eliminates several enemies, as indicated by the on-screen notifications. The game environment appears to be an indoor setting with concrete walls and floors. The lighting is dim, and the color palette is mostly gray and brown.
