Ice Fields is a level unique to Halo PC/Mac's multiplayer. It consists of two bases at either end, housing a shotgun, a flamethrower, and an Assault Rifle. There are two tunnels on the map, each leading to the center bridge, which holds the map's main overshield. Below the bridge, there are two teleporter exits. Near these are either active camo powerups or overshields.
The terrain of this map is comparable to the Campaign level Assault on the Control Room.
