SPRX is a file extension for executables designed to run on the PlayStation 3 Console. SPRX’s generally are created by “modders” in order to apply modifications to their game of choice. A few examples of popular SPRX’s are “Reflex Engine”, “Paradox”, “Serendipity”, etc...
The Reflex Engine SPRX on Black Ops II is awesome!
