 **Unity Studio** is a tool meant for exploring, extracting and exporting assets from Unity games and apps.
 
-It was built upon a lot of research and reverse engineering, with more than 400 apps and games tested from every version and every platform.
+It was built on a few years of research and reverse engineering, with more than 400 apps and games tested from every version and every platform.
 As such, it is compatible with Unity builds starting from 2.5.0 up until 5.2.2, the latest version to date, and platforms ranging from Web, PC, Linux, MacOS to Xbox360, PS3, Android and iOS.
