Multiplayer-centric 2011 shooter Brink has sold more than 2.5 million units worldwide, according to developer Splash Damage.

Studio CEO Paul Wedgewood revealed the figure in an interview with Gamasutra about the company's new publishing wing, called WarChest.

"With Splash Damage, we finished Brink, and it's estimated to have sold more than 2.5 million units worldwide, which at retail would mean that it's generated around $120-140 million in revenue," he explained.

"But of course, as an independent video game developer, we don't earn that kind of revenue, as we're not the publisher of the title... but we could see there was the potential to serve our fans content directly, and while we don't want to take anything away from what Splash Damage does, we wanted a vehicle that we can dedicate exclusively to that pursuit."

Which is where WarChest comes in. It will publish free-to-play digital titles, the first of which, iOS effort Rad Soldiers, was revealed earlier this week. The UK-based studio is also working on two unannounced AAA titles - one for PC and one for consoles.
