All of those people who signed up for Call of Duty Elite on Xbox 360 now have the oppurtunity to download two new maps for Modern Warfare 3. “Liberation” and “Piazza” are the names of the two maps that anyone can have as long as sign up for Elite. All you need to do is click the “Download Elite Content” button in the MW3 store (which can be found in the multiplayer menu). If you are Elite, you MUST download both maps at the same time or you will encounter matchmaking errors.
People who wish to buy the maps without an Elite subscription must wait, as do PS3 Elite premium members and PC gamers, who have yet to be offered the chance to buy Elite.
