make sure they are really, really good, get noticed by BUNGIE, and if they like the map they will put it in the next update.
No forge maps are designed to be made by and for the community you can't charge for that
Slayer DMR's on Countdown or SWAT on Powerhouse it's the best maps and game types around.
as part of the release of Halo Combat Evolved Anniversary a few maps for matchmaking were released for Halo Reach I think the dlc is about 1200 Microsoft points
You can download Anniversary Maps to Halo: Reach but not to Anniversary.
i do belive there will be a forge to make maps like Halo 3 did.
The Halo Reach Beta will include four maps. You can read about them here.
you cant >:(
yes you can on slayer. find a place to play in and it will say built in
Yes, you do.
The Heroic Maps, Cold Storage, and Legendary Maps are Required. The Mythic Maps, however, are not.
Its only the HALO:CE maps
you go to recent maps if its not their then its gone sorry.
