Halo 4 video shows off new enemy

343 Industries has published a Halo 4 video revealing details on new Promethean enemies, the Forerunners.

The Forerunners will be able to manipulate game environments and spawn other enemies, among other abilities.

Forerunners made a brief appearance in Halo Legends but it looks like they'll have a much bigger part to play in Halo 4.
