| If you are angry for whatever reason at the Krimzon Guard, and want to make them mad and not get killed for it, then complete these steps: 1- Get a Zoomer (they're the small fast little vehicles) 2- Go full speed aiming towards a guard 3- Right before you hit him, press Triangle to mount off 4- If you do it right, the vehicle will smash into him and he will receive damage, without raising any alarms | |

Glitch - Destroy Errol in last zoomer race | |
| It is possible to destroy Errol in the final race. All you have to do is force him to hit a wall (the large rock one works best). He will not regenerate and the cutscene once you win the race remains the same. This does not work with other races and it is also possible for you to be destroyed as well. | |
