Dos And Don'ts For Halo Modders
magnum76 on the Project Torlan-Nexus forum has posted an update on what is and is not acceptable to do in creating a Halo-themed mod, like theirs for Unreal Tournament; basically, it seems that extracting Halo content from PC Halo is okay, but extracting Halo 2 content from the Xbox is not. Keep in mind that the information comes from a supposed "Microsoft insider" and is not an official company statement.
