Facebook, that was once home to some addictive and extremely popular games, soon began losing to Android and iOS. Now, it has decided to give a big push into PC gaming with the Gameroom. The beta build is now officially open to developers, and is now available to download for users here , for Windows 7 and above. Facebook had revealed earlier in May that it is working on Games Arcade. It soon released further details about how the desktop app would work later in August . Now, finally, Gameroom is open to all. It’s a part of Facebook’s ongoing partnership with Unity and developers will reportedly be able to create games in Unity and export directly to Facebook Gameroom and WebGL. So, Gameroom is a PC app that will let users play web, ported mobile and native Gameroom games on the platform. Facebook has also posted a video showing how to integrate your Unity game with Facebook Gameroom. Clearly, it will go head-on with Steam, which has about 125 million active users. “It seems safe to say the pitch will revolve around its 1.75-billion users and the massive reach potential this offers developers. For a 30-percent revenue cut (the same as Steam), Facebook could potentially make your indie platformer the next billion-dollar indie sensation,” points out TheNextWeb. Steam may be everyone’s favourite, but lets not forget Facebook has a large user base. Many believe that Gamesroom could serve as a place for developers to bring heir games to attention of the hordes of Facebook users.
