These are the toughest Bosses of the three selectable Zones, found at the Technology Center. Although they both pose a major threat, Edgey is considered by many to be more dangerous because of his agility, dexterity and lightning speed. If you have fought Web Spinner from the Special Mode in Time Crisis on the PlayStation, Edgey is generally faster than him. Players that have a hard time hitting moving enemies should be extremely cautious of Edgey, and give him priority over Tiger. Note: Edgey's Naginatas can be shot down if your aim is good enough. If you are being "double teamed", make sure Edgey's offense is taken care of, then turn to Tiger (who is not the greater threat, but has massive stamina/life) and hold down the trigger, pumping as much lead into Tiger as possible before continuing.
In the previous game of the Crisis series (Time Crisis 2), a red flash/bullet from the enemy weapon signified a critical shot that would cost a life if you did not release the pedal. However, enemy shots in Crisis Zone travel much faster, so a bleep tone has now been included when a critical shot is fired. Some players may find it easier to avoid bullets/fire by listening for the tone, rather than looking for the red signal.
