Roxx Engine

The Roxx Engine is a game engine developed by NINE100 Studios for the Rock Heroes series.

Roxx Engine
The original Roxx Engine was developed as an improvement to the Guitar Hero: Warriors of Rock engine. Using the Fox Engine's graphics technology, NINE100 Studios were able to create higher definition backdrops for the game, along with more detailed musicians on stage. Also, the engine allowed for crowd members to be randomly generated, giving a different feel to each song played.

While the basic gameplay was kept from Warriors of Rock, there was some alterations with the layout of different features, such as the Ultrarock Meter being seperated from the instrument track.

Roxx Engine 2
Around the time development for Rock Heroes: Revolution began, NINE100 Studios began working on a modified version of the engine, simply dubbed Roxx Engine 2. The gameplay style that stemmed from this version of the engine is highly different from the main series, not needing the use of any instrument peripherals.
