GAMES:Chasm the Rift

This Quake clone works well, with audio, mouse, and high resolution support. Please note that the minimum stated requirement to run this game is a high-end 486 or Pentium CPU, and will therefore take a fairly powerful computer to run well within DOSbox.

It still works better than the similar engine used in Quake, that basically was unplayable on anything other than the middle-class Pentiums.
