Halo 3 is a first-person shooter, the third in the trilogy after Halo: Combat Evolved and Halo 2. You are the Master Chief, an artifically-augmented seven-foot supersoldier known as a Spartan to the United Nations Space Command Marine Corps and the Demon to the Covenant, a collected alien force made up of several different races. The Covenant believe that their purpose is to usher in Judgement Day, based on the teachings of the Prophets, of which only one remains. To do this, they must light the Halos, structures in space. Their real purpose, however, is to extinguish all sentient life in the universe, as they are a last resort weapon created by an ancient race, to eliminate any food source for the all-consuming hyperintelligent parasite known as the Flood.
Halo Wars is a real-time strategy game developed by Ensemble, the company behind Age of Empires. It takes place before the events of Halo: Combat Evolved, and tells the story of the previous Arbiter of the Covenant and the battle for control of the planet Harvest. The Covenant have uncovered a Forerunner artifact that leads to a site now occupied by humans. After travelling from planet to planet, a plot is uncovered that could threaten the survival of humanity.
AVAILABLE WORLDWIDE SEPT 22 2009
Halo 3: ODST is also a first-person shooter. You are the Rookie, an Orbital Drop Shock Trooper deployed to New Mombasa in Africa at the same time the Master Chief is fighting there in Halo 2. The Prophet of Regret's ship enters slipspace as your pod falls to earth, and the ensuing blast throws the city into disarray and separates you from the other four members of your squad. You wake up at night in the city, and are tasked with finding clues in the open world to the whereabouts of the rest of the squad, and relive their experiences through playable flashbacks.
Halo 3: ODST comes with two discs. One contains the ODST campaign, and a Horde-esque co-operative multiplayer mode for four people called Firefight. As time progresses, gameplay modifiers are added such as the enemies throwing more grenades or your HUD vanishing. If the team wipes, it's game over.
The second disc (known as Halo 3:Mythic) contains the standard Halo 3 multiplayer that we know and love, as well as all previous free and paid DLC maps. Also included are three new maps, Citadel, Longshore and Heretic. This disc is fully compatible with anyone playing vanilla Halo 3 multiplayer and has all the features you'd expect except for the Halo 3 campaign.
Still confused? Charts usually solve that problem - at least, for me.
AVAILABLE TBA 2010
Halo: Reach is a first-person shooter. Little is known at this time, other than it takes place immediately before the events of Halo: Combat Evolved, and will tell the story of the attack on the human-occupied and defensive cornerstone planet Reach by the Covenant. A multiplayer beta of Halo: Reach will be included with Halo: ODST.
