XCOM: Enemy Unknown gameplay set in the Halo Universe. I played it a few weeks ago and it was amazing and i could only imagine it set in the Haloverse.
Commanding a Squad of UNSC soldiers as they go up against the newly encountered Covenannt or perhaps a squad of Spartan IV's as they fight a new potential threat from the covenant and forerunner army? Thoughts?

How about a side story of some battles against the flood from the covenant perspective. Meaning you will probably be an Elite soldier and battle along side other covenant allies. Multilayer would be mostly the same mechanically as other Halo's, but with covenant maps, weapons and armors (including the arbiter's).
(I miss playing as an elite T_T)
