A repack is a compressed version of a game that is re-distributed by a third-party entity, often by modifying the game's original files to reduce its size, making it more accessible to a wider audience. Repacks are usually created by skilled gamers or groups who modify the game's files to remove unnecessary data, such as audio or video files, or to compress the game's overall size. This allows gamers with lower-end hardware or limited internet connectivity to play the game.
