Xbox bets on Gears of War in battle of gaming giants

Gears of War, one of the video games that helped Microsoft's Xbox to win over millions of fans, is back.
Prequel E-Day takes players back to where it all started, telling the origin story of humanity's conflict with The Locust - the series' horrifying enemy species.
The game's been well-received by critics and players, but it's also seen as a big test of Xbox's new direction.
