A new screen capture from Halo 4's presentation at the recent San Diego Comic Con leads us to believe that there may be a mech sequence in the game.
In the screenshot, Master Chief can be seen climbing into a giant mech. It's impossible to say what the mech sequence will be like, but given the series' penchant for wide open areas, don't be too surprised if the mech sequence happens in a large open field instead of a narrow corridor as it would in most other games.
Mech sequences aren't always the best, but when properly executed, they can be a helluva lot of fun.
Then again, there's a slight chance that the mech could be little more than a setpiece, and players may not actually have the opportunity to use it. So there's that.
Halo 4 comes out on November 6 for the Xbox 360.
