Halo 4 Forge Screenshots
Check out images of Forge mode in Halo 4.
Halo 4's Forge mode includes three new maps which are unique to Forge: Impact, Ravine and Erosion. In addition to the base model, each map also ships with a pre-made variant where some Forge strutures have already been constructed on the terrain. Erosion has two of these variants – one of which is a Grifball court.
