What are these Halo 3 mythic maps?

Hmmm I'm confused. What are they? When are they released? ahhhhh I want those millions of new achievements.

The mythic maps will be available for download eventually
I believe they are also working in more campaign if you've noticed the new trailers
There will be 5 new maps for download. The best you can do is work on the other 2 vidmaster achievements and the legendary ones

Keep you microsoft points and don't buy them, if I were you I would probably invest in a different game as halo is pretty outdated now.
