Halo 4 was a big title last week during Microsoft’s E3 press conference. A new Infinity Multiplayer experience trailer has recently been released to help supplement what was shown at the conference. Set nearly five years after the events of “Halo 3,” “Halo 4” follows the Master Chief and his faithful artificial intelligence (AI) companion Cortana as they venture into a mysterious new world and discover an overpowering ancient evil that threatens to annihilate mankind. With humanity’s fate hanging in the balance, the Master Chief and Cortana are thrust into a desperate mission against overwhelming odds to save mankind from the threat of imminent extinction. As one of the biggest video game franchises in history, the “Halo” series has sold more than 42 million games to date, generating nearly $3 billion in total franchise sales. “Halo 4” takes the award-winning series in a bold new direction, delivering its most epic and explorative campaign yet, together with a groundbreaking multiplayer offering rooted in “Halo” fiction —setting the stage for an epic new sci-fi saga. Take a look at the video below and tell us what you think about Halo 4.
