All Weapons and Infinite Ammo:
Pause the game and highlight the Weapons menu. Now press and hold RIGHT + L2 +
R2 + CIRCLE + SQUARE + X.
Defeating Anton Girdeaux:
When playing against Anton Girdeaux, try to always keep a pole between you and
him. Then he will be unable to see you. Hold L1 to manually aim whatever weapon
you want. (However, I do advise against either of the sniper rifles as they are rather
slow) Then hold L2 or R2 to peek out from behind the pole. Fire only at his gas
pack on his back. Otherwise it will hit his body armor. You can see his gas pack from
behind him when he turns to fire. Fire at the pack and let go of L1 and the other
shoulder button and press L2 or R2 by themselves to crank your tail away from the
flames. Repeat this about 5 times with .45 or about 10 times with the 9mm.
Defeating Rhoemer:
After you have push the button to the main computer, you watch a short film and start
real quick. Rhoemer is right behind you with a M-79. To get out of his way, make a
quick right behind the column. Take your quickest route to the opposite side of the
room (underneath the first window) This is a safe zone. Above you are two of
Rhoemer's men. Sniper them. Before this next step, make sure Rhoemer is directly
behind your computer. Check this by using the virus scanner you got a few boards
before. As soon as Rhoemer is in his place, throw a
hand grenade off the wall to scare him away. The second he runs, you run in the
direction of the second window and jump the computer. Sniper the other two people
in the second window, climb the wall, and get the gas grenades. If he is still where he
was when you through the grenade, gas him from the window. If he is by you, wait until
he peaks around the corner to gas him.
Defeating the Chopper:
Beating the chopper can be tough unless you know the proper way. First you will
need to learn the choppers two basic attack patterns and to be smart about evading the
its fire. What it does is that it kinda strafes from side to side shooting bursts at you and
then it drops down below the fence. Go to the edge and hold the lock on button and
start strafing and then start shootin. Repeat this step as much as you can until he starts
smoking. After it starts smoking, it unload a whole ton of lead at you so you better be
good at side stepping. First stand facing the ledge its rising from and when it appears,
lock on and roll (while shooting) along the edge as fast as possible from on corner to
the other. Its almost beat when it passes overhead so when it does that just lock on
and fire away and you should have it. Sometimes the chopper might drop some
terrorists down but they shouldnt be too much of a problem, just get in some quick
head shots then focus on the chopper again.
Level Select:
If you want to try this code , go ahead, but it is very hard to do, but i am sure it works.

press and hold L + L1 + R1 + S + S + X.

If you're lit on fire, quickly press the START button then press the START
button again. You'll be hurt, but alive.

Use the virus scanner to look through walls to see if an enemy is waiting for you.
