This video is a clip from a video game. The game appears to be set in a dark, dungeon-like environment with stone walls and floors. The player's character is holding a weapon, and there is a green, glowing substance on the ground. The character is standing over a defeated enemy, who is lying on the ground. The player's health bar is visible at the bottom of the screen, and there are two red bars at the top of the screen. The character then moves towards a doorway and enters it.
