Does Phoenix use the Halo engine?

It is unknown at this time whether Phoenix uses the Halo engine, a modified Halo engine, or something entirely different. It is widely believed that it is either the Halo engine or something based on it.


After the cancellation of Phoenix, Matt Soell at Bungie was asked whether Phoenix used the Halo engine.

He replied:

The original basis was the Halo engine, but like Halo (which began as an evolution of the Myth engine) there were significant differences between Phoenix's engine and the original code.
