After Microsoft accidentally published their E3 page on Xbox.com early, the reveal of Halo 4 wasn’t a huge surprise. Still it’s awesome to see Master Chief back in action again. The game is said to be the direct sequel to Halo 3, but be the start of an all new trilogy.
The trailer they revealed at E3 is short. Just a brief bit of the frozen Master Chief being woken up by Cortana only to have it revealed that they are under attack by some kind of massive ship or weapon. Could this be a Forerunner weapon? With the Covenant very unlikely to be the villains in the new trilogy, the Forerunners are a big possibility.
