Booster Rockets are on the backs of all the cars in Crash Tag Team Racing. To use them, they first must be charged up. They can be charged up by shooting at targets, other cars and power-sliding. Once they have been charged, the player can then press the power up button to activate them. They will send the player shooting along the track at top speed for a while before the effects wear off. They are also useful in some challenges. Sometimes, they will become charged upon collecting an item, instead of getting a weapon.
