Bungie released some new details about the upcoming Lendary Map Pack that is set to XBL on April 15th for 800 MS points.
Out of the three maps that are set to be released we now know about two of them: Ghost Town and Avalanche.
Avalanche is a remake of the classic Halo map, Sidewinder. Sidewinder was fan favorite from back in the day, but saw little play time due to it's massive size. Unless you had a huge LAN party rockin' you couldn't get enough people to fill the map.
So be on the lookout for Bungie to give us the last piece of the Legendary Map Pack puzzle soon.
