Hint: Level 1: Destroy tank at end: You will face an alien tank at the end of the first
level. The easiest way of destroying it is to just charge straight
at it. Fire like crazy while targeting it. If you run out of ammunition,
take out your blade and kill a nearby Borg. Once it explodes,
kill the remaining Borgs to win.

Hint: Level 1: Collapsed gantry: When The gantry collapses and you turn on the power,
the electric cable nearby will electrify the gantry. If you try
to cross, you will get hurt, and it is your only way back. Instead,
face the burning trucks and press R2 to switch to first
person view. Scroll left, look at the top of the building, and
shoot out the electrical box. This will cut off the electricity
on the gantry.

Hint: Level 1: Explosives: When you reach the door, go left and kill all the aliens
and bugs in that place. Use the gun turret up the top to have
an advantage. Once you have killed them all, one will drop an
alien key. Pick it up and open the gate. The resistance soldiers
will now give you some explosives.

Hint: Level 1: Detonator: When you reach the door, save and go the other way
(opposite from where you go for the explosives). Blow the sniper
out from his hiding place and keep going. Take a left turn and
run down the ramp. Kill the aliens and you will see yourself talking
to the resistance soldiers. Go downstairs and kill all the enemies.
Kill the alien and he will drop an alien keycard. Go towards the
next ramp and press the switch. It will show the alien gate being
turned off. Go through. You need to use stealth. If any of the
drones spot you, the gate will be turned on again. Once you are
through that room, run up to the alien gate and use the Alien
keycard. This will free the resistance soldiers and they will
give you the detonator.

Hint: Defeating Alien Troopers: Hold R1 and run around them, shooting them with
the laser. If they are in a group, they usually will not be paying
attention. Just stand back and shoot them in the head.

Hint: Defeating Alien Spiders: Stand back, fire one secondary rocket launcher attack,
a grenade (secondary machine gun), and finish it off with a laser
in the head. Be careful of the small ones. Stand far away and
blast them with the machine gun.

Hint: Defeating the Boss in the Alien Base:
After Dr. Carter gets captured by the aliens, you must
make your way through mazes and buildings to find her. When you
do, her father, who has turned into an alien himself, sends a
war drone after you, The best way to defeat it is to destroy the
laser arm on the left, followed by the one on the right. Every
now and then, pick up the items lying around. Once they are gone,
destroy the Drone. If the laser arm starts to fire at you, or
the drone brings out its machine guns, just press Triangle
to use your shields.

Hint: Defeating the final Boss: If you use the energy blade on the final Boss, he will
not be able to attack you until he has almost run out of life.
After that, he will only hit the ground. You will know if this
has worked because some big explosions will happen to him. Half
his life will also disappear.
