BOSS FIGHT STRATEGIES:
Mechanical Madness Zone
Avoid touching the hands in any state other than an attacking state, and make sure you keep your distance. Press a key for an attack, move in, then move out again before the attack finishes so you don't take damage.
Aquatic Paradise Zone
Your regular attacks won't work. Guide the boss's bombs to the box on the conveyor belt. If a bomb hits it, it will cause the main boss to whirl around and reveal it's head (weak point). Then you should stand by his head and guide the boss's bombs to it like you did the crate.
Hazardous Rail Zone
Run straight towards him and attack his head (weak point) when it is vulnerable (facing you). Keep your distance if the head is facing away from you, as you will take damage if you touch him in this state.
Urban Destruction Zone
Dodge the boss's particles and get as close as you can to the boss before firing lasers at him. The closer you are, the more damage you will deal.
If this game doesn't work on your machine, you may need to upgrade to the latest version of Adobe Flash Player.
