Valhalla returns in Halo 4!

The fan-favorite Halo 3 Multiplayer map Valhalla is back as Ragnarok in Halo 4.

Ragnarok is set in an area where some scientists believe that the Forerunners placed spire beacons within deep chasms to protect them from offworld debris and other external threats, while others believe they used the steep environment’s natural harmonics to amplify signals when firing deep into space.
