Halo 3: ODST is an excellent package. The delicate construction of the story adds a new wrinkle to the typical Halo plot, and the action-packed campaign levels are full of intense battles and surprising encounters. Firefight mode is a standout addition, crafting highly addictive cooperative battles for players to experience. It's disappointing that the competitive multiplayer hasn't received any updates or innovations from its Halo 3 incarnation, but it's as fun as it ever was, and well worth sinking more hours into if you haven't yet seen the many downloadable maps. ODST is a superb addition to the franchise and a must-play for anyone who craves top-notch action.
