Start the game while connected to Xbox Live and select the "Additional Content" option at the main menu. Choose the "Exclusive Content" option, 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 then 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.
