Razer and Sixense Release 'Ultra-Precise Motion Controller' SDK and FPS Utility Library on Steam

A couple of new developer-centric tools facilitating the integration of the bluntly-named "Ultra-Precise Motion Controller" were released today via Steam, Valve Software's digital distribution service. Created by PC gaming peripheral-maker Razer and technology developer Sixense, the tools mark the latest endeavor born from the multi-year partnership between the three companies, which was announced back in January.

With or without motion control, these Left 4 Dead 2 zombies aren't likely to last long.
