Crysis, released in 2007, introduced the nanosuit, a powered suit with modes for strength, speed, armour and cloak, and the cloak effect became one of its most iconic audio cues. Players activated it to turn almost invisible while sneaking past enemies, and the sound quickly became shorthand for stealth in first-person shooters. As gameplay clips and edits spread online, creators lifted the short effect for their own videos, where it still signals a silent, unseen move without any need for context from the original game.
