Super Danger Boost:
Ok, when you're coming up on the last stretch of a race, have your boost gauge somewhere near the top. When you're just about to finish, hit the boost and let the car heat up to the max (car go boom). When you blow up, it'll rocket you forward super-fast over the finish line. Just don't hit it too early!
Press Triangle twice or click R3 and move the stick around.
Boost without Rising Temp:
Tap x to use boost without raising the temperature. NOTE: this only happens if you have the patch 1.1 version of Motorstorm
When on a motorcycle, pressing Square will throw a punch at another biker. When you do it next to a car, however, your rider will attempt to communicate his frustration through interesting hand gestures.
