Rhine Forest is a multiplayer map in Call of Duty: World at War (Nintendo DS) based on the campaign level "Missed Delivery". It takes place in the ruined buildings located in the Rhine Forest. There are three houses in this map, two of which are accessible. One is destroyed and the second is two-story. There is a large road in the middle of the map, which divides the map in two and provides a long line of sight.
A hidden easter egg is located in the corner of this map. This easter egg is a small cave with a snowman inside that serves as an invincible barrier to players inside. The cave is located in the corner of the map (on the side with the large cabin) by a large rock and a doorway to a large cabin. To enter this cave, a player must crouch and and walk against a wall of snow. When a player finds the right spot, they will walk straight through and see a snowman with an black hat on its head. This easter egg is not able to be seen from outside of the cave, and players inside the cave can also not be seen. Players inside the cave can shoot outside the cave, despite that other players cannot shoot inside the cave.
