Grid


 * "Grid is made up of a series of small buildings, hangars, and generators across a snowy landscape, with a power/comms grid at one end." — InfectedPainter

Grid is a snowy map from Call of Duty: Black Ops. It has a few defendable positions, most notably on the roof of a single-story building on the opposite side of map to spawn. However, this is easily accessible for zombies by a very simple jump, so is often overrun in the mid to late stages of the round.
