You buy Rise of the Tomb Raider: 20 Year Celebration.
VERY IMPORTANT! You buy a version of the game WITHOUT REGIONAL RESTRICTIONS, which means that you can activate the key and play ANYWHERE IN THE WORLD where there is support for Xbox services. You will NOT have the risk of being banned for using a VPN, as is the case with keys for Argentina, Brazil or Turkey! In pursuit of cheap keys for these countries, there is a risk of losing the entire account with all games, because using such methods violates the license agreement with Microsoft!
