The video shows a first-person shooter game where the player is holding a gun and shooting at a zombie. The zombie is wearing a brown suit and has blood on its body. The player shoots the zombie multiple times, and the zombie falls to the ground. The player's health points are shown as "+67" in the bottom right corner of the screen. The game's HUD includes a pause button, a score counter, and a health bar. The environment is dark and appears to be a room with wooden walls and floors.
