Hint: Defeating Mara Aramov:
To defeat Mara Aramov on the train, get the AU300 out of the crate before you blow open the door with the explosives. Next, climb up on the train itself. Finally, walk forward so that you are near the beginning of the train. Aim through the train past the bullet proof glass and let Aramov have it with your new X-ray.

Take out your H11 and move back until you cannot see Mara, the hostage, and the fire. Keep aiming until you see "Head Shot" on the screen. Although the glass is bulletproof, when you move back there is a glitch that allows you to fire through.

Hint: Defeating Nigel Cummings:
At the Waterfront level, make sure you take the MIL15 (to the right of warehouse Maggie is in). Save at least three shots for the next level. When you receive the order to kill Cummings, take out the MIL15 and aim for the ground immediately beside him. If you kill him, you will see the body in front of the truck.

If you do not have the MIL15, run to the back of the truck so he cannot shoot you. Take out the two men on the right, and the first man on the left. After the two on the right are dead, sneak around the right of the truck an take out the other man on the left. It should now just be you and Nigel. Stay near the front right side of the truck, peek around the corner with R2, and kill him with a head shot.

Hint: Defeating Rhomer:
He is in the plane and has the body armor that Chance wore in Syphon Filter 2. Use the automatic shotgun and keep firing the weapon until he is blown off the ramp. To do this, you have to go to the pilot area and use the switch to lower the ramp. Do not kill the pilot -- avoid his pistol and return to Rhomer

Hint: C-5 Galaxy Transport: Level completion:
As you start, kill the man that runs up to you. Run to the right side of the plane and kill the hiding enemy. Run through the hall and shoot an approaching enemy. Rhomere will run down the steps, but do not follow him. Kill the man on the steps and collect the UAS-12 and flak jacket from the crate. Run up the steps and hit the switch to your left. Run back to the beginning of the level. Take cover, go into sniper vision, and peer around the corner. Use the same tactics as when Chance was fought in Syphon Filter 2. Shoot him out through the cargo door to complete the level.

Hint: Convoy: Flak jacket:
After fighting all the soldiers in the valley, turn to the left and you will notice a ledge. Climb up it, and in a crate will be a much needed flak jacket.

Hint: Hotel Fukushima: MIL15:
When you take out Shi-Hao's men in the first level, save the man in purple. Doing so will unlock a secret arena. When your done with those enemies, follow the path until you encounter a man with a shotgun standing next to a food shelf. Turn right and kick the door open. After a quick conversation, the terrorist/gangster will hand over the MIL15.

Hint: Hotel Fukushima: Get into Room 413 without a key:
You do not have to get the key to Room 413. Instead, go over to the bellhop at the elevator, take it up, go to Room 413 and press Triangle. Gabe will kick the door open.

Hint: Pugari Gold Mine: M-79:
Parachute in and skip ahead through the communiqué. Turn the parachute around 180 degrees. You should be able to see a ledge with a guard on it. Parachute so you can access the ledge and shoot the guard with your 9mm. He was protecting the M-79. You can use it now or save it for later. From here, you can jump back onto the crane structure. Make sure you take the guard out first. He will have spotted you and can shoot you up badly.

Hint: Pugari Gold Mine: Crossbow:
After getting the explosives, instead of going right into the tunnel turn right. There will be a crate on a ledge. The crossbow is in the crate. After collecting it, continue with the mission. Note: A crossbow can shoot through a Flack Jacket.

Hint: Pugari Gold Mine: Gas Grenades:
When you parachute and play as Mujari, shoot the terrorist with a head shot from your pistol and shoot the other guard that walks on the cliff. Then, go to the "Jump here" message that and go to the weapons crate to get the Gas Grenades. You will also get the normal grenades. You will need these weapons for enemies wearing flak jackets. If you happen to stun yourself with a Gas Grenade, your character will put his or her hand over his mouth

Hint: Pugari Complex: Get hit by truck:
Talk to Foreman Joe. When you are done, kill him and look out of the large window. You will see two headlights turn on. A huge dumptruck will appear and hit the building. Alternately, do not kill him and run outside directly in front of the truck. Aim through the window and shoot him in the head. Turn around and the truck will run over you and hit the building. This may require more than one attempt.

Hint: Pugari Complex: M79:
After killing Foreman Jones, run up the ramp to go on with the next section. To the right, have Gabe jump up and run back towards the office. There is an M79 in a crate.

Hint: Senate Building: Grenades:
Enter the women's bathroom (the one without the stalls) and go into the last toilet. A "???" will appear. Press Triangle to get ten grenades.

Hint: Waterfront: MIL15:
After destroying a truck, run towards the open area where you will receive an escort from an MI6 operative. To the right of the loading dock is a MIL15.

Hint: Whispering Woods: Corpse:
Play a mini-game in Whispering Woods. Run up the steps of the building and slide through the trapdoor. Run down the hall to find a man with no skin on his stomach.

Hint: Multi-player Slums: Stay alive:
Do move from your position. A good spot to hide is upstairs in the passage with the blooper. Hide by the blooper so you can see into the room and as much as possible around the corner toward the passage you came in. Have a G-18 ready with plenty of ammunition. By the massive hole in the ground, run to the other side by the M-16 and shimmy round against the wall. You can just sit on that tiny ledge. Have a blooper ready. Also, on top of where you get the HK5, get in a small alley near the large ramp. Note: Use the shotgun only at close range. If it is close enough, one shot will kill.
