Forge is the name of the level editor that shipped with Marathon Infinity by Bungie. It was a touched up version of the Vulcan editor used internally on the Marathon Trilogy, and also came with the Anvil tool for editing the game's art assets. The name Forge was later re-used for the map editor included with Bungie's Halo 3. Prior to the release of Forge in 1996, a fan made editor called Pfhorte was released March 1995. Modern community made tools include Pfhorge and Weland.
