343 Industries has just released an interesting video and a set of pictures that show us a new multiplayer map in Halo 4 : Ragnarok, remake of the popular Halo 3 map Valhalla . But the video shows us something even more interesting: the possibilities in multiplayer to drive even the mech Mantis, that will create real clashes in Mechwarrior style. Of course these are only present in certain maps and modes, so there is a danger for a general turnaround in the balance of the game.

We show you everything: the official movie of 343 also add two videos we've found on the net, where it shows the gameplay of Mantis, piloted with third-person view, and a long session of game Ragnarok. Good vision!
