This video is a clip from a video game. The game features a character with a blue glowing symbol on their chest, who is fighting a large, gray creature with a red collar. The creature is standing in a room with purple walls and a neon light pattern on the floor. The character is using a lightning attack to hit the creature, causing it to take damage. The creature is shown taking multiple hits and is eventually defeated. The character then proceeds to pick up a treasure chest that appears on the floor.
