Stage 8 – The Ultimate Power
----------------------------

Mission Objective – Find the Frequency Code for the Aura Beast kill switch in 
one of the labs.

There is a Field Medical Kit to the right, and if you dig in the back with TK 
(in the debris) another Field Medical Kit and a Shotgun will be waiting.  
There is some Pistol ammo behind the crate on the left and another Shotgun 
behind the crate in the back.  Go to the door in the back.
(2 x Health power-up, 1 x Pistol Ammo, 2 x Shotgun)

RV through the door at the end and try to sneak up on the MP2 in the next 
room.  If you are seen, MP2's and MP3's will swarm the room.  Turn off the 
alarm next to the door in the back.  Use AV to see some freaky stuff on the 
back wall.  A Psi Rejuvenator and a Psi Vial are on some shelves to the side 
and a Field Medical Pack is on the wall between the sets of tubes.
(1 x Health power-up, 2 x Psi power-up)

There are 2 MP3's and 1 MP2 in the next room.  The MP2 likes to charge you as 
soon as the door is opened.  The MP3's are hiding behind metal crates on each 
side.  After taking down the MP2, Open the door, TK an explosive canister, 
move it into the room with the MP3's, and throw it off to either side and you 
might just hear a yell.  Try this with both canisters.  If it doesn't work you 
always have the metal crates off to the sides.  There is a Field Medical Kit 
off to the right side (behind the metal crate) as you enter the room.  The 
door against the right side is a definite "NO!" right now, as it contains tons 
of Aura Beasts.  The doorway to the left of that door has a device that will 
not be of any use for the time being.  There is a Field Medical Pack, a box of 
Pistol ammo (in the back), and an Assault Rifle in it however.  Go through the 
door on the left side of the hall.
(2 x Health power-up, 1 x Pistol ammo, 1 x Assault Rifle) 

Only 2 MP2's in this room.  Kill them and use AV to see a code on the back 
left wall (middle board).  The code is random.  2 Psi Vials are on the 
shelves, a Field Medical Pack is on the sidewall, and a Field Medical Kit is 
behind the tubes on the right.  Go back out of the room and go through the 
doorway on the left and up to the glowing teleporter.
(2 x Health power-up, 2 x Psi power-up)

Mission Objective – Find the Frequency Input Device, and enter the Frequency 
Code to eradicate the Aura Beast – for a while...

(Note: For this next section I have found two ways to do this part.  If you MC 
the MP2, the first part is easier, but the second part is killer.  If you do 
the first part with Nick, the first part can get bad, but the second part is a 
little bit easier.)

MC the MP2 that appears outside the doorway.  He is the only one that will 
appear.  If you do kill him, you have to go through all the Aura Beasts 
yourself to do this.  You will have unlimited Psi power while controlling the 
MP2.  Either way, go through the door that leads to the room of Aura Beasts.  
Go into the back (run if you are doing this with Nick) and through the door to 
the left.  Now go to the back controls and enter the code that you saw with AV 
just a few moments ago.  This will get rid of the Aura Beasts in the outside 
room for a while.  

Mission Objective – Meet up with Sara in the Map Room.

The Aura Beast will be gone for a total of 4 minutes.  Don't worry too much 
about the time limit, you can always go back and reenter the code for some 
extra time if you start to run low.  Now, if you're controlling the MP2, you 
could send him out in style with a suicide (See Secrets) or you could send him 
back out the door and have him take some of his buddies with him.  Whatever 
you choose, don't forget, you have infinite Psi while controlling him.  If you 
didn't MC the MP2 go back outside the door and take out the onslaught of MP3's 
and MP2's outside.  If you did MC the MP2 go through the door ahead and face 
this same onslaught of enemies, but from a much harder angle, because they are 
all in your face.

Either way, whatever room you are in, go toward the room that the Aura Beasts 
used to inhabit.  There are 4 MP3's in here and 2 MP2's.  TK the metal crates 
and explosive canisters off to the side and throw them at the MP3's.  A 
shotgun helps out a lot for this battle.  Go through the doorway off to the 
side.  There is a Field Medical Kit behind the metal crate.  Go through the 
door on the right and walk into the room.
(1 x Health power-up)

Mission Objective – Locate Wrightson's inner chamber and save Sara.

Go back out of the room and back through the doorway.  Go down the right side.  
MC the MP2 through the glass next to the door at the end.  Have him press the 
red switch.  Release MC and go through the newly opened door.  

There are two Field Medical Kits on each side of the wall, Pistol Ammo to the 
right, a Field Medical Kit on the back right and a Psi Rejuvenator on the back 
left.  MC the MP2 through the glass to the right, and have him press the red 
switch in front of him.  Release MC and go through the door ahead.
(2 x Health power-up, 1 Psi power-up, 1 x Pistol ammo)

===============================
Boss battle - Nicolas Wrightson
===============================

There are two Assault Rifles and a Field Medical Kit against the left wall, a 
Shotgun against the right wall in about the middle, and two Psi Elixirs in the 
back on each side.  This battle is much easier than any of the previous boss 
battles once you know how to take him down.  Try to stay away from the middle 
area of the room if possible.  Aura Beasts will attack if you venture off in 
the middle.  The Aura Beasts are basically the only frustrating part of this 
battle.  Use one of your weapons to take them out if they start to attack.  

His attacks come from the monitors in front of him.  When a monitor rises up 
it will fire out a yellow beam.  Dodge the beam by moving to the side.  In 
order to get rid of Wrightson, the monitors in front of him must be destroyed.  
To destroy them, TK one of the small metal crates off to the side and move it 
toward a monitor.  Let go of the TK button slightly, so the crate lowers. Move 
the crate behind the group of monitors.  Now hold down on the TK button and TK 
throw the crate toward the back of a monitor (toward you).  If you get the 
crate in between two monitors, you can destroy two at a time.  If a monitor is 
shooting out a beam it can be hit from the front.  Once the monitors are all 
destroyed the battle is over.

{There are some additional strategies for this boss battle in the Additional 
Strategies section}

---------------------------------------------------------

Mission Objective – Explore the excavation tunnels and confront Barret and the 
General.

There is a Psi Rejuvenator, which you can barely see through the structure to 
the left, behind you.  You can TK it through the structure.  Go through the 
door up ahead and through the next door after that.
(1 x Psi power-up)

There is a Psi Rejuvenator on the left, a Field Medical Kit on the right, and 
two Assault Rifles behind the rocks up ahead.  Go up to the entrance of the 
cave.  This whole next area inside this cave is killer.  There are 5 MP3's 
inside and one of them in the back has a missile launcher.  Grab the crane in 
the middle with TK and swing it off to the left or right.  You are nearly 
guaranteed to hit at least one MP3 with it.  One of the MP3's will most likely 
charge you.  Usually the only MP3 left will be the one in the back with a 
missile launcher.  Try to TK an explosive canister or a rock and throw it at 
him.  I have actually held a rock in front of him and he would kill himself by 
blasting the rock. :)  Some Pistol Ammo is near the back right column, a Field 
Medical Kit is next to the back left column, and a Psi Rejuvenator is behind 
the front left column.  Use AV to survey your surroundings and see the 
Invisible Mines in this area.  The mines are instant one-hit deaths!  Drop 
down in the front area of the middle hole.
(2 x Health power-up, 2 x Psi power-up, 1 x Pistol ammo, 2 x Assault Rifle)

{An additional strategy for this tough area and the extremely tough area 
afterwards can be found in the Additional Strategies section}

An MP3 is up ahead.  TK a rock and throw it at him.  A Field Medical Kit is 
behind the rocks in the back.  Another Field Medical Kit is down the back 
right path along with an Assault Rifle, and a Field Medical Pack is down the 
back left path.  The only way that I have found to get past the mines on each 
side is to throw an enemy into them.  Be sure to use AV to see the mine in 
front of you.  Go by the mine in front of you by staying on the right side.  
The path on the right has two Psi Vials and a Psi Rejuvenator at the end.  
Both mines can be avoided by staying on the left side (duck for the one in the 
back).  Go down the path on the left.  In AV there will be footsteps going up 
the path.  A rock will eventually spring up out of the ground.  PK the rock to 
destroy it.  Take care of the MP3.  RV into the next room and try to plan out 
a stealth attack.  Go through the door.
(2 x Health power-up, 3 Psi power-up, 1 x Assault Rifle)


Take care of the MP3 up ahead.  Two Sniper Rifles are against the back wall 
and a Field Medical Kit is on the right.  I would highly recommend picking up 
the Sniper and going down the path on the right.  There is Psi Vial, Psi 
Rejuvenator, and Field Medical Pack down the path on the right.  The straight 
path holds a Field Medical Pack and some Pistol Ammo.  Weave through the mines 
on the right path.  You will have to move some of the rocks with TK in order 
to pass by some of them.  There is an MP3 in the back with a rocket launcher 
(this MP3 is MAJOR pain if you go down the other path at the beginning of this 
area).  Use the Sniper Rifle to shoot the grenade on his belt for and instant 
kill.  There will be some more MP3's in the water, below you, off to the left.  
There is a Field Medical Kit, two Sniper Rifles, and a Psi Rejuvenator in the 
water below.  Pistol ammo and a Field Medical Kit are behind some rocks up 
ahead.  Go to the path ahead.  3 MP3's will be in the back hiding behind 
rocks.  Try to take them out with the Sniper Rifle or TK a rock and throw it 
at them.  There is a secret item behind a group of rocks at the end of this 
path (see Secrets).  Go through the doorway at the end.
(4 x Health power-up, 3 x Psi power-up, 1 x Pistol ammo, 4 x Sniper Rifle, 1 x 
Evil Garden Gnome)

Go down the metal bridge/catwalk of the greenish room.  Be sure to use AV and 
avoid each mine; I would hate to see you go back through all that again. :)  
Duck down and go below each of the mines.  Stay to the appropriate side for 
each mine and you should be fine.  A cutscene will eventually interrupt your 
progress.  After the cutscene grab the Field Medical Kit and the Psi 
Rejuvenator ahead.  Get on the orange platform.
(1 x Health power-up, 1 x Psi power-up)

=========================
Boss battle – The General
=========================

There are 3 Field Medical Kits and 1 Field Medical Pack in the trenches around 
the area where the General is.  At the start of the battle run up to the 
spinning rocks and PK them.  Each one has to be PK'ed twice to be destroyed.  
It is best to get beside them and turn to the right or left and PK them as 
they go by.  As each one is destroyed, it will leave behind an orb.  Grab the 
orbs after all (or some) of the rocks have been destroyed.  Don't be afraid to 
use any Psi power-ups that you might have.  If you get in the glowing area, 
below the General, your psi meter will replenish slowly.  Beware of the 
massive shockwave that he will send out eventually.  Get off the platform 
after about 5 seconds of recharging to avoid the shockwave.  Try to collect 
all 6 orbs if possible.  When his health has filled up all the way, or you 
have collected all the orbs he will come after you.

First and foremost for this battle, do NOT stand still for too long.  If your 
life meter is down halfway or below, by all means, heal yourself at any time 
during this battle.  He has three attacks.  He always starts off by picking up 
some rock fragments and hurling them your way.  Keep moving to avoid the 
fragments.  His next attack will be a continuous rain of fireballs.  Stay 
moving to avoid this attack as well.  Eventually, he will disappear.  When he 
reappears he will shoot out some incredibly fast blue projectiles.  These can 
be avoided by jumping the second he shoots them out or by hiding under one of 
the small bridges in the trench around the middle area.  To attack him, shoot 
one of the orbs that you collected earlier at him with the R button.  To 
refill the orb shots or psi energy run into the glowing area in the middle.  
If you did not collect any of the orbs, the fragments of rock that he throws 
at you can be thrown back at him with TK.  The fragments have to be multi-
lifted in order to hit him sometimes.  Use any health or psi power-ups that 
you have and be sure to keep moving.

(4 x Health power-up)
