Rockstar Games has a knack for including intriguing detail within its open-world games. This is more apparent than ever in the Grand Theft Auto franchise, with each title offering new Easter eggs and enigmas that leave players scrambling for clues years after release. Fortunately, Grand Theft Auto Online is no exception, with ghosts that haunt Mount Gordo to aliens providing Rockstar fans with a plethora of brand-new mysteries to sink their teeth into. However, none of these secrets is more prevalent within the community than the mysteries surrounding GTA Online's Mount Chiliad.
