If there is a game that marked a before and after in the future of Microsoft by industry of game consoles was Halo. Launched in 2002, was the first major title for the first Xbox, one of those who say the 'must buy' and sets a benchmark for first person shooters that are made today.

The solid single player campaign, the variety in gameplay and a strong commitment to multiplayer 'online' were the three foundations on which it stood. And after him, have been arriving a second and third, a quarter with a tangential to the main story that told us the trilogy and numerous comic books and movies. All very successful.

The series, set in the distant future, introduces us to an intergalactic conflict between humanity and the Covenant (Covenant), a collective of alien races united by a religious fanaticism that drives them to want to exterminate the heresy they think is the race human.

The main protagonist of the story is the Master Chief, a human soldier powerful GM, the only one left of its kind, the Spartan II, and has become an icon for Microsoft.

And here comes Reach Halo for Xbox 360, the final closure of the saga is a prequel to the main story. No one Spartan, but many, and the war with the Covenant is starting.
