The Halo series tends to polarise gamers. First-person shooter purists hate the game with a passion, yet their combined hatred can't deny that Halo is one of the biggest video game franchises of all time.
With more than 42 million games sold (not including Halo 4) and nearly US$3
billion ($3.6 billion) in revenue, its makers have obviously been doing something right.
Halo 4 marks the first game since 343 Industries took over the franchise from Bungie Studios, and the expectations of millions of fans weighed heavily upon its shoulders.
Set nearly five years after Halo 3, Halo 4 follows the Master Chief and his AI companion Cortana as they venture into a mysterious new world and discover an 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 imminent extinction.
