You can view the video for the Annihilation map pack on the Call Of Duty website. Hanger 18 is based off Area 51 from the Roswell alien landing. it is a medium sized map with all pathes leading to the hanger which houses an SR71 Blackbird. Control of the hanger leads to domination. Silo is based off a Russian nuke constuction site. It is one of the largest maps in the game. there is lots of flank paths, the key is to keep moving. Drive-in is small like Nuketown, and open in the middle. Its close on the sides for run and gunners. (Our Lady) Hazard is based off a World at War map called Cliffside. It has been coverted into a golf course that focuses on long distance.The zombie map, Shangrila, will have alot of areas to get trapped, and lots of ways to escape. There will be new weapons and new ways to move around. This zombie map will be smaller than Call Of the Dead.
