Maps
"Soviet forces have infiltrated a highly classified U.S. facility"
 * Hangar 18


 * This is a medium sized map, set in the secret military base, Area 51. It has numerous Easter eggs, such as alien corpses, and a floating apple.


 * Silo
 * "Conflict erupts at a missile launch facility. Lots of close engagements and flank routes"


 * It is said to be one of the biggest maps in Black Ops. Silo takes place at a Russian missile plant in the U.S.S.R.


 * Hazard
 * "Keep an eye out for snipers as you battle up and down the fairway of this Cliffside golf course"


 * The map takes place on a golf course, and according to Treyarch, it is based off Cliffside from Call of Duty: World at War. This map was originally going to be called "Golf Course" as seen in the game's files. It favors long-range combat, so sniper rifles excel here. SMGs and LMG's are a good choice too.


 * Drive-in
 * "Close-quarter fights and powerful over watches at an abandoned outdoor cinema"


 * It appears to be very small and favors close quarters combat, but has some sniping positions. There are also a alleys that would favor the use of assault rifles and LMGs rather than the use of SMGs or Shotguns.


 * Shangri-La
 * "A legendary shrine lost in an exotic jungle. Where the undead lurk within a treacherous labyrinth of underground caverns, deadly traps and dark secrets."


 * Zombies return with vengeance in the mysterious land of "Shangri-La," a legendary shrine lost in an exotic jungle. Never before seen undead creatures lurk within a treacherous labyrinth of underground caverns. Step carefully through deadly traps and solve the dark secrets buried within the shifting walls of a long lost land.
