The video shows a first-person view of a player holding a gun and moving through a dark, medieval-style building. The player is looking for enemies and shooting at them. The environment is dimly lit, with only a few light sources visible. The player moves through hallways and rooms, taking cover behind objects and shooting at enemies that appear in front of them. The gunfire is loud and the enemies are defeated with a few shots. The video ends with the player continuing to move through the building, looking for more enemies.
