Red Ball 4 is a rolling platform game in which the player guides a small red ball through obstacle-filled levels, jumping over gaps and dodging enemies before facing a larger boss. The boss charge cue comes from those encounters, where a short warning tells the player that a heavy enemy is about to rush forward. Clips from the game have since circulated on soundboards and in gameplay edits, where the brief, instantly readable cue is reused whenever a creator needs a sudden sense of danger.
