was created by Julian Aubourg
and was the first Doom
source port to have room-over-room
capabilities. Based on Boom
, it was released in 2000 shortly before EDGE
, which provided with 3D floors
a different approach to room-over-room design. EDGE gained in popularity, and RORDoom's authors stopped their effort.
In RORDoom, level designers could create sectors on top of other sectors, thus breaking the rule of non-overlapping areas. BSP tree pre-compilation was done as usual, and RORDoom's engine detected subsectors that belonged to several sectors at loading time.
