Essence of the UNSC
*Gain ownership of a UNSC world similar to Reach in population and geography before it was glassed. This world has the industry and technology to build most human technology of the UNSC save for the most exotic like the UNSC Infinity.
*Its population is loyal and will rapidly increase to the point where you can expand into new colonies after a few decades.
*You have a solid defense force that would make the UNSC proud whether it be the Army, Marines or Navy. There are even a number of Marathon and refitted Halcyon class like the Autumn was before it was lost.
*Interestingly you seem to have your own little SPARTAN program with a handful of Spartan II's, Spartan III's, and the more easily mass produced Spartan IV's
*Can optionally be dropped into the setting of Halo
