That said, if they were to expand on the SpOps in some of the ways you describe, I'd like to see them take cues from ODST as well. Slowly moving through the city with a small group of fellow ODSTs, salvaging weapons and vehicles from fallen marines and covenant, engaging patrols, exploring the dark corners of the map, slowly piecing together a narrative about what transpired the previous day, then jumping into proper missions at each waypoint was awesome in that game and I'd love to see more of it. It could easily be molded into something more Destiny-esque while still retaining the great Halo gameplay.
