You have the ability to gain infinite energy for a short period of time. While in the game press L2, R2, and R3(right analog button) at the same time. You will get a system error message and for about a minute your boost energy will be unlimited. After that minute is past, all boost energy will be completely depleted for the same amount of time. After this your energy will recharge and you may repeat the cycle. This is extremely useful when fighting quick enemies in the Arena.
