E6M3 (aka American's Legacy) is the last of three bonus levels in the Heretic: Shadow of the Serpent Riders expansion. This level and episode name are in fact untitled and can only be accessed via a warp command. According to the Heretic FAQ, a map creator by the name of Sailor Scout came up with the name Fate's Path for the episode name and American Legacy for the map name. The wHeretic source port offers this "episode" on the main menu using the names Sailor Scout assigned (although the automap shows the map title as "American's Legacy"). This level was designed by American McGee and resembles his Doom II level IDMAP01.WAD, and it is possible that the IDMAP01 is actually an early version of the Heretic level. This level also appears in the three episode version of Heretic as E4M1.
