In GTA Online, players can engage in Gang Attacks during their free roam of San Andreas. Gang Attacks are only unlocked at Rank 18 via Martin Madrazo, who will call the player character and introduce the optional side missions.
Martin informs the player that he needs a few hideouts to be wiped out, but he’s more concerned with tying up loose ends than retrieving any loot stashed there. As such, anything the player finds during the raid, they can keep. There are various gang locations on the GTA 5 map, which are highlighted by a red area.
