Get Marathon for free — is it possible?
Even though Marathon free download is unlikely, you can take advantage of our price comparison engine and find best prices right now, or create a price alert and get notified once Marathon is on sale and hits the price you want.
Can I activate Marathon in my region?
Most distribution platforms (like Steam) have regional restrictions and different prices for each game: e.g., Marathon will cost more for customers from United States than from Argentina, but customers from US cannot activate Argentina’s Marathon key.
We show this regional restrictions information under “Region” in our filters and in the list of Marathon offers. For instance, “Marathon Global” means it can be activated in any country, “Marathon Europe” – only in Europe, and “Marathon Japan” — in Japan only.
However, some shops do not provide regional information, so the best way to make sure Marathon 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 Marathon offers from official stores and keyshops?
Official stores get their Marathon 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 Marathon key is not working.
