Can I activate Cartridge Defense in my region?
Most distribution platforms (like Steam) have regional restrictions and different prices for each game: e.g., Cartridge Defense will cost more for customers from United States than from Argentina, but customers from US cannot activate Argentina’s Cartridge Defense key.
We show this regional restrictions information under “Region” in our filters and in the list of Cartridge Defense offers. For instance, “Cartridge Defense Global” means it can be activated in any country, “Cartridge Defense Europe” – only in Europe, and “Cartridge Defense Japan” — in Japan only.
However, some shops do not provide regional information, so the best way to make sure Cartridge Defense 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 Cartridge Defense offers from official stores and keyshops?
Official stores get their Cartridge Defense 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 Cartridge Defense key is not working.
