10 Hilarious But Utterly Game Breaking Glitches

10. The Madd Dogg Mission - Grand Theft Auto: San Andreas

The Grand Theft Auto franchise has among the most entertaining mods in gaming. Depending on what mod you're using, you can cover the city in water, make cars blow up for no reason, or let meteors rain down upon civilians.

One that stands out for GTA: San Andreas is the Pedestrian Riot Mod, which causes every character to kill each other or themselves. This mod is fun but it poses a serious problem for key missions. At one point, you have to stop a character called Madd Dogg from jumping off a building. If the Pedestrian Riot Mod is active, Madd Dogg will take his own life one second after the mission begins, making it impossible to complete. It's funny when this occurs because the text reads "Save Madd Dogg before he jumps" after he's already splattered on the floor.

But here's the real problem. If you use the Pedestrian Riot Mod and turn it off before you reach Madd Dogg, he will still kill himself the instant the mission begins. Since you can't save him in time, it's impossible to progress, meaning you have to start the game all over again.
