Happy Bungie Day everyone! Today is 7/7/2009, the day where Bungie gives back to the community of loyal Halo enthusiasts. One of the things that Bungie has done today is reveal the three new multiplayer maps that will come on the Halo 3 multiplayer disc included with ODST.
The three maps are Heretic, Longshore, and Citadel. Heretic is based on the Halo 2 map Midship while the other two are never before seen designs.
