Cascade Falls takes you through a lush jungle environment complete with rivers and spectacular waterfalls. Water is designed be as big a feature here as mud was in the first game. Rivers have current and drag, meaning they can slow down smaller vehicles or even carry them along. On the plus side, all that cool water can be used to cool an overheating engine. Motorstorm aficionados will remember that using boost was the key to success in the first game, but when used to excess it could result in your vehicle exploding. Taking your racing truck or buggy for a quick swim can help stave that off if you're pushing your engine to its critical mass.
