Sword is a member on the MGM forums. Sword is renown for his creation of the Swordedit application for Mac. The program is currently one of the best scenario editors out there for editing maps. It supports loading a bitmap for incredibly detailed map editing. Many mods which feature a new vehicle set or structure were created in part by Swordedit.
