At the Penny Arcade Expo this past weekend, a special build of Halo 3 was spotted. The screenshot released showed a new menu screen with the word "Mythic" underneath the Halo 3 title. Many theorized that this could be a new single player expansion and now it's looking even more likely.
A thread on the Ascendant Justice forums, a Halo fan site, contains a supposedly leaked list of achievements to come with the Mythic expansion. There are a total of 30 achievements adding up to 750 gamerpoints.
What do you guys think? Think this is legit? Bungie has been planning something big and while another map pack would be cool, they seem to be hyping this announcement up to be something even grander. I think a new expansion seems just about right.
