Crackdown Cheats

During the fight with Miss Timbol of Shai-Gen, there are two buildings to the east and west of her compound. On the side of those buildings that faces the compound is a walkway with two doorways into the buildings. After killing Miss Timbol, pick up her body and take it to those walkways and enter into the building. Immediately go back out and Miss Timbol should be alive and completely harmless. This is an exceptional way to level up your Explosives, Physical, and Shooting stats. However, do not let her body out of sight, or else it will despawn and she'll never come back.

Lift an object. Jump with the A button. At the height of your jump, press RT to throw the object and immediately press and hold the A button to do a double jump. It might take some practice but it DOES work.
