So the remake of Halo CE has been confirmed to have multiplayer maps that run in the Reach engine and will be playable in Reach online multiplayer. They confirmed that there will be 7 remakes of halo 1 and 2 maps for us. I figured out what three of the seven remade multiplayer maps are. In an interview one of the games developers said that they were showing off Damnatioin to lucky players at E3. I re-watched the Trailer shown at Microsoft's press conference several times and I have come to the conclusion that Battle Creek, Damnation, and Hang 'Em High are three of the maps shown.
Well I hope the other four include terminal and headlong, as those were two of my favorite halo 2 maps.
