 A third meter increases after each combo and allows when maxed out to perform a " Code Drive " attack . Executed with the triangle button , a Code Drive triggers a brief close @-@ up sequence in which a blue circle appears around the character . If the player presses a second button before the circle shifts to red , a powerful special attack will be unleashed . If the enemy blocks the Code Drive , a second , shorter close @-@ up sequence is triggered . Enemies can also perform Code Drives , in which case the player 's button press allows for protection rather than attack . Executing Code Drives frequently can cause the weapon used to upgrade , or the character to go into a " Code Crisis " ; a mode which reduces speed and renders immune to attack , but slowly drains hit points .
