PART 1 - CHARACTER: Nina. CORTEX
As soon as you start, the twin parrots will be
sending out there little light saber dudes. Don't worry about these,
just head for one of the 6 poles/stands, and make your way up them by
using Nina's bionic arm and the metal rings/hooks. Once at the top,
break open the blue orb light, then swing over to the other pole, and
destroy that orb. Each time you destroy an orb you will take 1 life out
of Maurice and Victor's robot. Destroy all the orbs, and you will change
character, and the Twins' robot will change their claws into guns, a
machine gun, and a blue ray gun.
PART 2 - CHARACTER: Neo. CORTEX
You will have infinite ammo on your weapon. When
the twins start firing their machine gun at you, keep running one way,
and the twins will charge up their ray gun and fire, but watch out for
after it hits the floor, the ray gun will disperse outwards, once you
know you are out of the way of the rays shot, charge your weopon and aim
at their machine gun, shoot their machine gun, and keep travveling in
the same direction, dodge the machine shots, and the ray blast again,
then charge and fire your weapon at their machine gun again. Continue
this until they loose their machine gun arm, after Maurice and Victors
robot looses the arm keep moving away from the ray gun and after he
fires at you you will have a short period of time to launch an attack on
their ray guna arm,dodge the ray guna attack and start shooting at the
arm again, keep doing this until they loose this arm. Another short
video will come up, and you will see Crash inside of Cortex's failed
invention, Bionic Crash (The first boss). Maurice and Victor will move
to the centre of the arena and summon a saber sword.
PART 3 - CHARACTER: Crash BANDICOOT
3 sky high shields will rotate around the twins, keep running one way,
and when they attempt to hit you with their saber sword,  the shields
will split and create openings, stand at an opening were the twins are
not waving their sword around, and fire your missiles into the inside of
the shields. Do this 3 times and there you go, you have just beaten the
final boss of Crash Bandiccot: Twinsanity, Now you will be treated with
a video, mmm... roast parrot!
