The video is a first-person shooter game where the player is shooting at zombies in a dark and gritty environment. The player is holding a gun and is shooting at the zombies, which are falling to the ground as they are hit. The environment is dimly lit, with a lot of shadows and a grim atmosphere. The zombies are wearing tattered clothing and have blood on them. The player's gun is visible in the lower part of the screen, and there is a crosshair in the center of the screen that the player is using to aim at the zombies. There is also a text overlay on the screen that says "Hold [Weapon] (5001) Upgraded Ammo (4500)".
