World Heroes 2, a sequel to the original, expands on the gameplay with new characters, moves, and stages, while retaining the fast-paced fighting system. The ALM-006 and ALH-006 designations likely represent minor variations in the arcade release.  The game maintains the series' distinct style of combining history and fantasy characters in exciting combat. ADK continued to refine the World Heroes formula in this sequel.
