One of the biggest games to be shown off this year at E3 was Halo 4. The game is the first in the series not to be developed by Bungie and has been in development since 2009 by 343 Industries.
The game is said to be set "some time" after the events of Halo 3 and will see the return of the main protagonist from the original trilogy Master Chief. This will be the first time since 2007 that he has made an appearance, the last 2 Halo titles focussed around other characters and alternative game play.
While the gameplay will obviously be much the same as the previous titles, hopefully 343 can inject their own bit of something into it. I will look forward to saving the world with Master Chief once again at the end of the year.
