"You've laid eyes on Heretic before, both as "Midship" in Halo 2 and through the small looking glass we provided by way of one of the images on our Halo 3: ODST Product Page. But since today is Bungie Day, we figured you deserved a little bit more perspective. Here's a sneak peak at Heretic, Citadel, and Longshore, three maps you'll find packed into the Halo 3 multiplayer disc included with Halo 3: ODST. Click each image to make huge."
I hope we will be able to install the Halo 3 Multiplayer disk on the HD...
Evan Wells (Uncharted 2): I think the differences that you see between any two games has much more to do with the developer than whether it’s on the Xbox or PS3.
