The video is a screen recording of a video game. The game appears to be a side-scrolling platformer with pixelated graphics. The main character is seen running through a dark level, jumping over gaps, and shooting at enemies. The character is equipped with a gun that fires projectiles. The game's HUD is visible, showing the character's health, ammunition, and other game-related information. The character moves fluidly through the level, avoiding obstacles and enemies. The game's graphics are reminiscent of retro games from the 1980s and 1990s.
