Creating a new Halo experience that spans an entire device ecosystem was a critical challenge for one of Microsoft's premier Xbox properties. Halo: Spartan Assault was Microsoft Studios and 343 Industries' bold move to expand the Halo universe to screens of all sizes - from Windows 8 Phone to Xbox One. Creating new and compelling audio IP meant overcoming a myriad of challenges along the way, and executing on a winning strategy for each platform. Microsoft Studios and Halo publishing audio director Paul Lipson will take attendees on a guided tour of the strategies, tactics, technology and creative techniques used to transition the classic FPS experience into a top down, dual stick shooter for Windows 8 PCs, tablets, phones, Xbox 360 and Xbox One. Topics will include loudness standards, content tweaks and listener considerations, top down vs. fps conversion, platform challenges and a host of leanings around transitioning big console IP to an entire device ecosystem.
