Shadow Warrior used a further iteration of the same Build engine. It came with a huge map that had all the map effects demoed, and there were a lot of them, something like fifty (so if you were building a map, you could copy an effect). For example, there was a room above a room, and a moving hole in the floor/ceiling between them.
