In the video, a person is playing a video game on a mobile device. The game appears to be a third-person shooter, and the player is controlling a character who is shooting at enemies in an urban environment. The player's thumbs are visible on the screen, and they are using them to control the game. The game's graphics are relatively simple, with a focus on the action rather than detailed textures. The player moves the character around the environment, aiming and shooting at enemies as they appear. The game seems to be fast-paced and requires quick reflexes.
