New Halo 3 achievements viewable, more than expected and Mythic maps

Later today, Bungie will release the second Halo 3 title update and with it a set of ten new achievements will be added which allows an additional 250 Gamerscore to be unlocked. All are now viewable on along with (surprise!) a bunch of additional achievements that haven't been officially announced. These additional achievements total 500 in Gamerscore which bumps Halo 3's total Gamerscore to a whopping 1750!

The additional achievements look to be the same ones that were leaked from PAX a few weeks ago which are the ones Bungie made it clear they wouldn't be talking about just yet. It's interesting to note that a few of these newer achievements make mention of "Mythic" maps, referring to six different (and yet to be announced) multiplayer maps called Assembly, Citadel, Heretic, Longshore, Orbital and Sandbox. Or so we think they're multiplayer maps.

Whatever is going on, we're totally out of the loop because Bungie technically only announced that the ten Legendary achievements would be included in today's H3 update. Maybe the posting of additional 500 Gamerscore worth of achievements was a mix-up by the folks OR maybe the Superintendent has something to do with this. We're confused, but REALLY excited!
