Pixel Gun 3D is a blocky first person shooter for mobile, first released in 2013 by Cubic Games, with multiplayer battles, campaign levels and zombie themed modes. Short enemy sounds like this groan became easy material for soundboards because they are instantly recognisable, loop cleanly in edits and need no context to understand. Players shared clips from zombie rounds across YouTube and gaming communities, and editors kept reusing the snarl outside the game as a quick horror cue. Its brevity and familiar game distortion keep it popular for memes.
