Heroes is similar to the Tron and Nibbles games of yore, but it includes several graphical improvements and new game features. It features 12 original soundtracks and 94 levels in 10 different tile sets. Two of the five game modes include Quest, the classical Nibbles, and Kill em all, in which you run over lemmings. This is a port to UNIX of the DOS version. This version has been split into four packages with different version numbering and release schedules because only the source code is modified often.
