Sanctuary

Sanctuary (originally a cut map named Meteora ) is a multiplayer and survival mode map that was released along with Foundation in Content Pack 4 for Call of Duty: Modern Warfare 3, April 10th 2012 for the Xbox Live Elite Community. Based on the Call of Duty Elite description, it takes place in a monastery in Greece.

Trivia

 * If the player goes to any of the three grassy patches near the middle of the map, they can hear ghostly voices saying "Hehe, look at me, daddy! Hehe!", "Don't get too close to the road, sweetie", and "Sarah, don't go too far!" The voices are sound clips taken from "Davis Family Vacation."
 * In the graveyard, Sarah's mother can be heard by the large box casket with the pillar sticking out, near the building. Alternatively, she can be heard between the box casket near the entrance that isn't the church nor the tunnel, and the wall to the left of said casket. Go prone and face the spawn for the Inner Circle (located at the bottom left corner of the minimap; the horizontal rectangle colored blue.) if the player goes next to the red gate near a stack of barrels, they can hear monks chanting.
 * In the sanctuary, behind a red curtain can be found a teddy bear sitting on a chair. Though, this can only be seen by free spectating.
 * Near the cemetery, a small structure can be found, decorated with pottery and flowers. Two small trees and a bush also emerge from the top of the structure. If the player moves close enough, he can see that the insignia on the structure is in fact an 'Elite' skull, and above this skull is the Infinity Ward logo.
 * This map was origianally called "Meteroa," which was a cut map before this map's release.
 * On one corner of the map there is a ledge that can be reached giving the player a better view on the main bridge.
