Metal Slug 3 is a run and gun arcade game released by SNK in 2000, later ported to home consoles and PC. Its heavy weapons, including the shotgun, became favourites for their exaggerated power and clear audio cues during crowded battles. The shotgun blast spread online through gameplay videos, fan edits and soundboard collections as players reused retro effects outside the game. It is often grouped with other shooter effects like the Fortnite pump shotgun, even though its dry arcade tone is older, sharper and more compressed.
