SnakeInBox

SnakeInBox was a Metal Gear Solid Delta: Snake Eater global emote built around one of Metal Gear's oldest stealth jokes: Snake hiding inside a cardboard box. Konami even used the line "What's in the (cardboard) box!" in its own material for the remake.

The Snake in this game is Naked Snake, not Solid Snake. Metal Gear Solid Delta faithfully remakes Metal Gear Solid 3: Snake Eater, the 2004 story that shows how Naked Snake's legend was forged and leads toward the man later known as Big Boss. He is sent behind enemy lines during the Cold War, where camouflage, survival and avoiding detection are central to the mission. The cardboard box takes that serious stealth premise and pushes it into one of the series' most recognizable absurdities.

When this emote was active, viewers typed SnakeInBox in Twitch chat to use it. Viewers used SnakeInBox during Metal Gear streams for cardboard-box jokes, stealth plays, hiding from enemies, sneaking past guards, or escapes that worked despite looking ridiculous.
