The video is a first-person shooter game where the player is holding a gun and moving through a building. The player aims down the sights of the gun, shooting at enemies and earning points for each hit. The environment is dark and dusty, with debris and rubble scattered around. The player moves through different rooms and corridors, taking cover behind objects and aiming at enemies. The gun's sights are red, and the player earns points for each hit, which are displayed in the bottom right corner of the screen.
