G2A Marketplace is the official app from G2A, the popular video game sales portal. G2A sells keys for Steam, Origin, Uplay, and Battle.net, all of which can be registered on their respective platforms. This makes it possible to buy lots of games at slightly cheaper prices.
From G2A Marketplace, you can buy and even pre-order the latest PC games at a much lower price than on Steam or Origin. For example, releases which are typically priced around $50 may cost as little as $25 on G2A. And, of course, G2A guarantees that all the keys work perfectly.
With this official app, you can browse offers and keep track of all the keys you've bought via G2A. Although the portal is dedicated almost exclusively to PC games, there are also some keys for PSN and Xbox Live.
G2A Marketplace is a good official app from a very interesting video game sales portal. Although some users are hesitant to buy keys from Steam and similar services, G2A is backed by hundreds of thousands of satisfied customers.
