Note: the download link there is broken. You may find all versions of RTC here: DMFiles Shared OneDrive (in the folder Clones / Return To Chaos)

This clone features the original graphics and dungeons for both Dungeon Master, Chaos Strikes Back and Dungeon Master II, but customization is possible: you can replace all the graphics and sounds.
There are discussion forums about RTC at Cowsmanaut's Dungeon Master Forums.

The DM wiki contains loads of information about RTC.
