Yes.

Refering to halo 3 and halo reach their is a custom forge game mode, here you can build and shape your very own map creations for both custom and recreational use.
To play local on halo reach, start at the title screen when you start up the game. Hit main menu, then custom games. That is local gaming. (Meaning people on your xbox, not system link. For system link I don't know how.)
