Philip Reed, I believe (one "l"), though oddly his name and the name of his co-author do not appear in the core rules.Sadly its not as complete. It has a few bugaboos with trying to avoid the default usage of powers (Nine Lives, I think.) It's usage of Karma was an improvement. However, it needs a lot of work to be a whole game with solid, and clear explanations of how things work.
It also wasn't Porter, but Phillip Reed.
