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