This means that fans are just now discovering that Grand Theft Auto: San Andreas - The Definitive Edition is missing the co-op/multiplayer mode from the original San Andreas game. As some may recall, the original Grand Theft Auto: San Andreas had a secret co-op mode that fans could trigger by going to a special icon not far from CJ's house at Grove Street. If players had a second controller and a second player handy, the second player could choose from a variety of GTA San Andreas characters and then they could wreak havoc on the open world together.
