This is a just-over-two-second voice clip of Heavy from Team Fortress 2 saying “Oh, this is bad” in his deep, heavy voice. The line lands with sudden worry and dawning dread, the feeling of realising a mistake a second too late. It comes from Valve’s Team Fortress 2, where Heavy is one of the game’s most recognisable characters.
