Newegg Shipping Halo: ODST early

I pre-ordered from Newegg, and it arrived Monday Sept 14th.

Play'd it through the first night on Heroic (6 hours).
It was fun.
No dual wielding.
No battle rifle.
You move surprisingly fast with a turret.
No match-making for firefight (yet?).

Halo: Mythic is a separate disk, with:

• Matchmaking
• Custom Games
• Theater
• Forge

...and ALL the multilayer maps.

Heretic is Midship.
Cathedral is like Epitaph, but VERY symmetrical.
Longshore seems pretty cool.

You play them off Mythic, you don't download them to your HD. Your Halo3 saved content is available from with-in Mythic automatically.
