"The AA-12 is an automatic primary shotgun that utilizes a 20-round drum magazine for sustained close-range combat. It deals 150 damage at maximum upgrade and operates at 300 RPM, providing consistent pressure in tight spaces. With a x1.9 damage multiplier to mutants, it functions as a versatile tool for both clearing threats and engaging players. Its high volume of fire and ease of use make it a forgiving choice for players who prioritize capacity over individual shot weight."
