The new elemental Conflux town adds a new mystical environment to the Heroes of Might and Magic III universe. There are seven new veteran Heroes, each with unique characteristics and abilities, over twelve new neutral creatures to recruit, two new Conflux hero classes (sixteen heroes in total), new artifacts, and a slew of fearsome new dragons. The map editor and random map generator have been updated to handle all the new features. There are also 6 new campaigns and over 35 stand-alone missions.
During the development phase of Armageddon's Blade, 3DO unveiled a ninth town - the Forge Town, which was to bring high technology and a futuristic setting to the game. However, the fans panned this move due to the "distastefulness" of the town (especially some concepts, like the bare-breasted Naga Tank). 3DO employees also received death threats via mail, so they scrapped the Forge Town in favour of the Conflux.
The cheat codes in this expansion are all references to Star Wars Episode I, NwcDarthMaul for example.
