Hint: Liberty Island mission: Programmer message:
At the end of the level, enter the head of the Statue of Liberty to see a programmer message in lights.

Hint: Soviet Domination mission: Police station weapons:
After talking to the policeman at the end of the tunnel, crouch, then walk directly forward to the left of the wall. You will see an open door. Walk in it towards the underground parking garage. Near most police cars there will be a shotgun. Be careful, because there are enemies.

Hint: Thin Ice mission: Kill your own soldiers:
Your first objective is to destroy the ventilation shaft so that your troops can roll up inside. After you complete the objective, send one of your troops to the middle of the destroyed fans. Then, throw a grenade at them. Some will just duck and when the grenade explodes; they will fall down and die.

To kill your own soldiers on this level, simply order one of them to go to the edge of the ice. Then either throw a grenade by him, or go over to him and punch him. Eventually he will fall in the water and freeze to death. The best way may be to get a rocket launcher (enable the code if needed) as well as the "Flymo Ragdoll" code. Shoot the rocket near the man. He will fly in the air then fall into the water. It will take him a long time to get up, but when he does he automatically dies.

Go to the edge of the level and tell your people to defend. Step back and enable the "Rocket launcher" code. Shoot them and they will fall into the water and die.

Hint: Defeating General Tatarin:
To easily kill General Tatarin on your first trip to Governors Island, sneak down to where you have to go right over all the barriers. Take out those troops and look for a wall that is shorter than the buildings beside it. Try to look over the barrier to see a basement entrance. Then, look for a window that has a light behind it. Enable the "Rocket launcher, miscellaneous items" code. Fire at the window and the "Killed Tatarin" message should appear. Then, run away quickly. Alternately, walk down the same way, but get on top of the crates. There will be a guardrail where the first fence segment ends. If you are lucky, you can jump to it, climb the rail, and find the door. You will fight various opponents and finally the General. If you enable the "Blind Enemies" code, it will be a lot easier, and you can kill General Tatarin with any weapon.

Hint: Hair length:
While playing the game, notice that Chris' hair gets longer with every mission.

Hint: 3600 round machine gun:
At any level before the stage where you have to kill General Tatarin, go to the rebel base. Go in circles around it to find a machine gun that has 3600 rounds.

Hint: Hitman references:
Play the level where you liberate the fire station. When you go to the railroad to blow the bridge, when you first get down there you will see a derailed boxcar with the IO logo and "47 UNITED".
Squall123872.

Play the level where you seize the police station. From where you start, go to the streets. On the one corner is a red, white, and blue diner with the name of "OG's". On top is a billboard for a men's suit designer, featuring 47.

At the very start of the game when you are looking out the window and the helicopter arrives, run into the second room on your right and turn your camera. Look at the wall near the kitchen. You will see a picture of Agent 47 on the poster.

Glitch: Chris' identity:
Later in the game, Tatiana Kampinski (the news lady) states that the Freedom Phantom has been unmasked. However, if you look at some of the wanted posters near the bottom with binoculars or a sniper scope, it will read "AKA: Chris".

Glitch: High definition television:
If you have a HDTV and have selected to turn on the "Video" features of 480, 720, 1080 through the XBOX dashboard, it will cause the video to be blank even though you can hear the audio. To make the game work, go into the "Video" options through the XBOX dashboard and turn off all the video options. Restart the game and the video should work.
