At the main menu, select the "Additional Content" option, and choose the "Promotion Code" selection. Then, enter one of the following case-sensitive codes to activate the corresponding cheat function:

Bonus missions

Enter "2Eprunef", "6aPHuswe", "96CesuHu", "Cr34ufrE", "JeM8SpaW", "sa7eSUPR", "SpujeN7x", "tar3QuzU", "THaCupR4", "tr99pUkA", or "zUmU6Rup" as a case-sensitive code to unlock the "The Georgian", "The Bolivian", "Special Delivery", and "Le Français" missions. If you entered the correctly, the message "You have successfully unlocked the missions" will appear. Start a new game or continue a saved game. Pause the game, and display the "Map Legend" menu. You will see a new envelop legend labeled "Special Mission". Successfully complete the tutorial and a few missions. You will eventually get a phone call from a distorted voice that sends you on your "predecessor's tracks". Go to the envelop map legend location to find an old bus that is now a shack, and continue.

Special machetes

Start the game with a connection to Xbox Live. At the main menu, select the "Additional Content" option. Choose the "Exclusive Content" selection, then login with your Ubisoft account information or create a new account. After the game connects to the Ubisoft servers to verify your information, the message "ACCOUNT LINKING COMPLETE! Thank you for linking your Ubisoft account to your Xbox LIVE Gamertag. Special Machete. Unlock Special Machete" will appear. Press A to unlock the special machete. The message "The exclusive content was successfully unlocked" will appear. Return to the main menu. Select "Options", then select "Game". A new "Machete Type" option will appear. You now have access to the "Homemade" and "Primitive" machetes on the current profile.
Golden AK47 locations

When in the Northern District (the area where you start), look at the map. You will see a bus station at almost each corner of the map (top left, top right, bottom left, and bottom right). Go to the bottom right bus station by following the road south, but use the road closest to the edge of the map. Then, follow the road north to the gun shop. From there, take the road northeast, then take the next right. The road should dead-end at a small shack on the other side of the mountain from the gun shop. The diamond light should flash. Inside the shack you will find a golden AK47, some ammunition, and a diamond case. Note: Put the golden AK47 in a primary case so you never lose it. -From: Keith McKenzie

Unlock all missions

Apart from the obvious beeping in your PDA about the diamond case, there are additional clues you can use to find your diamond quota.

When your map is zoomed into the maximum magnification in a region, there is a small green (or blue) number on the map indicating the number of diamond caches in that zone. This, plus the lit points of diamond caches you've found, can be used to help you narrow down the areas you need to search.
