This right here is PEAK Halo and PEAK Xbox 360. The hours- the days- the months- the YEARS I spent playing this game solo, with my brother, with friends, couch co-op, and online. The firefight maps are spectacular. The online game modes were legendary (although around 2014 they updated a bunch of the maps, ruining Sword Base on Infection mode in my opinion). No Forge mode has ever been this good and the campaign is one of the greatest Halo campaigns. Noble Team will forever live in my gaming books as some of the greats. This game is one of the few reasons I hesitated selling my 360 collection. Thank god its included in the Master Chief collection on PC. I return to this game at least once every few years.
