By far my favorite map from Halo 2 is coming to Halo 3 with a new name (Blackout) and a new look.  This version of Lockout has more of a human feel to it and looks to be positioned on a body of water.  This map will be part of the Legendary Map pack due out April 15th.  I'm totally stoked for this map because one thing Halo 3 needs is better smaller maps.  The legendary map pack comes with a remake of the Halo map Sidewinder named Avalanche and a new map called Ghost Town.
