Forest was a planned multiplayer map in Call of Duty 4: Modern Warfare. All that is known to prove its existence is a file called "compass_map_mp_forest.iwi" present in the game's source files.
The map is of a forest, as the name suggests. The terrain varies from place to place; the south is primarily flat, while the north appears to have bluffs and cliffs. A river with pink water runs through the map; the water is pink most likely because the water texture used was a preliminary texture. To the west are three small buildings. This map was likely replaced by the map Creek.
