Sonikku used to draw out maps in MSPaint, listing the floor/ceiling heights, and where he wanted important items. I would then take these maps and build the level, usually in DCK 3.62.
Some notable anecdotes...
GFZ1 is actually the original GFZ1 and GFZ2 put together, and an extension added on (it originally ended at the spikes - see Demo 1).
THZ1 is quite a bit bigger (originally it ended at the long hallway halfway through the map, then we extended it, then I added on the factory bit at the end). Originally, the steam pipes were four multicolored fan platforms.
The original THZ2 was totally scrapped. If you come across it, you'll understand why. The railing texture in modern-day THZ2 was a few of the survivors.
DSZ2 is a combination of:
*) Very old DSZ1 by Sonikku
*) My own DSZ1 using a new motif that most of can be seen in the SAGE 2000 video. This set the tone for the level's future direction.
*) A new MSPaint map by Sonikku and mapped out by Mystic (the waterslides at the end of the level come from this).
CEZ1 contains some elements from one of the other DSZ maps that Sonikku made - the one room with the broken fountain and some castle ruins. This is the only level whose base layout was drawn out by Mystic, and is why we don't let him make any more single player maps (hur hur we love you, Mystic). Of course, I was the one that made it into a map, so there must be enough fault to go around...
RVZ1 is arguably quite intact from its original version. Some of the layout shows its age, but I think it works pretty well for the most part. Nev3r did a great job at making this map look more awesome.
ERZ1 contains some elements from the original old map (large windows on the sides, red and yellow caution stripes, crushing stuff).
The 'secret' road in ACZ1 is just part of the many experiments that Nev3r was doing with the map. At one time there was also some kind of train track sequence.
