The mode will automatically appear for North American players in the game's main menu. According to the post, the mode was originally planned to be available through a code in the game's box.
"We really want to make it available to anybody that plays the game," the post reads, "so we want to take a new approach."
Contracts Mode will still be free for those in other regions; however, they'll have to follow the company's original plan. Redeemable codes will be available inside the game box, or as a free download through the online store.
