Call of Duty- Black Ops - Berlin Wall Full Trailer 

 Berlin Wall is a medium-large urban snow set terrain map set in Germany with several large buildings and a "No-man's land", where indestructible automatic turrets fire at the player if they step on the territory. The "No-man's land" is highlighted in red on the mini-map to show its danger. There is also a small path in the middle of "No-man's land" which leads to both sides of the map. The map is good for camping, sniping, and long range combat. There are several windows/holes that can see great distances (such as over to the other side of the map), making this map ideal for snipers or campers. On one side of the map there is an ally checkpoint, with small security buildings, gates and tanks. The "No-man's land" is great for a quick getaway, but the player must consider it at the risk of having to face the Auto Turrets. It has now been confirmed that there is a way to get through 'No Mans Land' with out the need of perks etc. If the player throws smoke grenades and runs through the smoke, the turrets will not shoot.
