Speaking at Gamescom, a spokesperson for the studio said “I want to stress, it’s following the same business model as World of Tanks. It’s free-to-play, but of course we need to sell some stuff in the game to make some money.”
However, it looks like the content you’ll be able to buy won’t give you an edge in your gameplay: “as it is for World of Tanks, you don’t buy any competitive advantage, you’re not going to be able to buy a super weapon that’s way more powerful, but you’ll be able to buy some skins. It’s not going to be getting power, and in terms of content, you’re not going to be buying extra modes or stuff like that.”
