Deadly Rooms of Death: Architects' Edition is the updated version of Caravel Software's Deadly Rooms of Death. The game itself is identical, but has one major improvement—a level editor (hence Architects' Edition). So in addition to delving through the 25 levels of King Dugan's Dungeon that were first introduced in Webfoot's original version of DROD, you can build your own dungeons (or "holds"), and play other people's creations. Architects' Edition also adds support for multiple players on the same installation, so your saved games are kept independent from anyone else's, and many other small improvements.
