Hydro Thunder Cheats for XBox
Also on: PlayStation, Nintendo 64, Dreamcast, Arcade
On the level Lake Powell Get a booster. When you come to the part where there is a bridge and policeman on top of the bridge use your boost.
NOTE: You must start boost when you first see the bridge. Hit the middle part of the bridge to get huge air, a 9 second boost, and knock a train off of it's tracks. This doesn't do you much good except for the boost but it is a neat trick.
