In Halo 4 was recreated one the most popular maps among the community, Valhalla. It comes with a new name and a new vehicle. The name is Ragnarok and the vehicle, to be more specific is a mech, is the Mantis.
The Mantis is fully equipped with machine-guns, rockets, and can foot-stomp its way through the enemy lines. It’s effective against all other vehicles and viceversa; and Spartans can board and bomb it.
Below you can find the full trailer of the mantis in action. Enjoy and stay tuned for more.
