The best cheat in GTA: San Andreas was easily ‘Crazy Peds’. It armed all the citizens of San Andreas and sent them on a violent riot. You couldn’t drive down the street without a hail of bullets and grenades flying your way.
Unfortunately, Rockstar didn’t include the same mode for GTA V.
Happily, modders have fixed that:
You can find the mod over on GTA V mods. Here’s the description:
Financial meltdown. Apocalypse. Doomsday. You provide the scenario, and we’ll provide the chaos.
In this mod, all the pedestrians have weapons, and every single one woke up on the wrong side of the bed this morning. While they’ll target anybody, they’ll also shoot you if you come too close, so watch your distance as you attempt to roam in this chaotic world.
