Unity has launched version 4.2 of its game development platform, adding Windows Phone 8 and BlackBerry 10 to its supported mobile platforms.
Pro users can also publish games to the Windows Store, used on Windows 8 and RT devices including Microsofts Surface tablets.
The platform has been compatible with Android and iOS for a while now, and made them available for smaller developers back in May.
Unitys technology has been behind a host of games since its initial launch on desktop back in 2005, and has made a smooth transition to mobile, powering games including Temple Run 2 and Rovios Angry Birds spin-off Bad Piggies.
