Grand Theft Auto Online
Several versions of the apartment swap bug let players repeatedly generate large amounts of cash by exploiting property sale values. It became one of GTA Online's most infamous economy exploits.
Using garages, MOCs, arena workshops, or save timing, players found many ways to duplicate high-value vehicles for resale. Rockstar has patched countless variants.
At times players could enter or leave passive mode in ways that still allowed aggression, explosives, or griefing actions to go through. It broke the intended safety rule.
Jobs, props, or character transitions have repeatedly allowed players to get inside normally sealed buildings, casino spaces, or hidden map interiors. These glitches are popular for hiding and trolling.
Certain timing exploits let players avoid or recover the intended high cost of Orbital Cannon use. That turned an expensive weapon into a much more abusable option.
