Can I activate Castle Defender in my region?
Most distribution platforms (like Steam) have regional restrictions and different prices for each game: e.g., Castle Defender will cost more for customers from United States than from Argentina, but customers from US cannot activate Argentina’s Castle Defender key.
We show this regional restrictions information under “Region” in our filters and in the list of Castle Defender offers. For instance, “Castle Defender Global” means it can be activated in any country, “Castle Defender Europe” – only in Europe, and “Castle Defender Japan” — in Japan only.
However, some shops do not provide regional information, so the best way to make sure Castle Defender will be activated in your region is to visit shop’s product page: there’s always a special block next to the price that shows if it can be activated in your country or not.
What is the difference between Castle Defender offers from official stores and keyshops?
Official stores get their Castle Defender keys directly from game developers or publishers, while keyshops resell keys from unknown sources.
Keyshops are usually cheaper than official stores, but they are riskier. We recommend reading keyshops’ and sellers’ customer reviews first. Also, most keyshops have buyer’s protection programs to guarantee a refund in case Castle Defender key is not working.
