Reward Bug Exploitation
When you have completed all the mission objectives, don't exit yet. Instead, press F1 for the mission status screen to appear. When the "success" message appears press ESC to go back to the game. Then repeat the process. Each time you will be paid the reward for the mission.

Press the following keys after enabling the ip_debug code:

Result - Code:

Kill with no weapon - [Shift] + [F12]
Jump - J
Wire frame graphics1 - T
Free camera mode - K
View rooms in wire frame mode - Y
Teleport - F

Instant kill:
Enable the ip_debug 1 code. Place the pointer over a person and press [Shift] + [F11].

Launch enemies:
Enable the ip_debug 1 code. Leave the console, then press [Tab] until you find a selected enemy. Press [Shift] + [F12] to make them fly about in the air. This will kill the target. Make sure you have the crosshairs over your enemy, or it will not work.

Multiple Gun Combo Trick
This trick will let you have up to 15 rounds in any gun.

1. Make sure that you have a Beretta 92 in your inventory.
2. Select the gun you want to have 15 rounds in, and make sure that is the ONLY thing you are holding.
3. Drop the gun on the floor.
4. Take out your Beretta 92 and pick up the gun you just dropped.
5. You will be holding both guns at the same time, and you will have 15 rounds in both guns since they always shoot together.(Alternatively you can press ctrl button after point 2 and select Beretta 92 from the menu)

Easter Egg
On the Traditions of the Trade mission there is a minor easter egg. When talking to the recepient you will look in the guest book for Mr.Wuffs room. In the guest book there are some names from the IO team, for example Martin Guldbaek and Rasmus Kjaer from the graphics and design team. And Mads Olson from the tester squad. And Martins room has the number 666 while Rasmus and Mads have numbers 301 and 302. 301 and 302 are the rooms just above the rooms 201 and 202 where Mr.Wuff is accomodated.

Access All Missions
Type 'Kim Bo Kastekniv' as your profile name, you'll get instant access to all missions.

Extra Money
Successfully complete all objectives in a mission, then press [F1] to display the mission status screen. Press (Esc) when the ''Success'' message is displayed to return to the game. Repeat these steps to collect the mission reward multiple times.

Slow motion.
When you start any level in Hitman, switch 'Scroll Lock' on to walk around in slow motion. This is very effective if you are shooting at a lot of bad guys as your cursor will move as if you weren't in slow motion. To switch off, press 'Scroll Lock' again.
