Multiple Gun Combo

This trick will let you have up to 15 rounds in any gun. Make sure that you have a Beretta 92 in your inventory. Select the gun you want to have 15 rounds in, and make sure that is the ONLY thing you are holding. Drop the gun on the floor. Take out your Beretta 92 and pick up the gun you just dropped. You will be holding both guns at the same time, and you will have 15 rounds in both guns since they always shoot together

Access All Missions

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

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.

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.
