Warhammer 40,000: Space Marine: regions, activation and buying a key
Which Warhammer 40,000: Space Marine key works in my country?
GLOBAL keys activate anywhere. EUROPE keys work for accounts in Europe, US / NA keys in the United States (often also Canada), UK keys in the United Kingdom, and ROW (rest of world) keys only outside Europe, the US and the UK. Choose your region above and the list shows only keys you can activate. Offers marked “Region: check” don’t state the region in the title – read the product description first. Keys locked to single countries (Turkey, Argentina, India…) are not listed.
How do I activate a Warhammer 40,000: Space Marine key?
Warhammer 40,000: Space Marine is offered as Steam, Xbox, GOG. After payment the code arrives by e-mail or in your store account. Activate Steam keys in the Steam client via Add a Game → Activate a Product on Steam, Xbox and PlayStation codes in their stores and Ubisoft Connect keys in the Ubisoft app. The exact steps are in the product description.
What is the difference between a key, a gift and an account?
A key is a code you activate on your own account. A gift is sent by the store to your account as a gift. A shared account is not your own account – that’s why accounts are hidden by default.
Why is Warhammer 40,000: Space Marine cheaper than on Steam?
Key stores buy licences in bulk or regionally and resell them for less. We take prices from official partner feeds once a day, so they may differ slightly – the store price is binding. Stores list prices in EUR, so USD and GBP prices are converted at the daily exchange rate and are approximate.
