Team Fortress 2, Valve's free-to-play team shooter, introduced Heavy as its slow, powerful Russian gunner, voiced by Gary Schwartz, while Metal Slug is SNK's long-running Neo Geo arcade run-and-gun series known for its loud announcer and weapon callouts. This clip is a fan-made crossover that puts Heavy's shotgun line into that arcade style, and it follows an earlier version of the same idea using a heavy machine gun line. Fans reuse it in TF2 edits and gaming memes because it instantly connects two nostalgic shooters, the 1990s arcade era and the humour of Heavy's simple, heavy delivery.
