Ok, only mapping is left to do, and this basically involves downloading one of the *.t3d files generated by the MMC (Marathon Map Converter) made by randomer, and then re-working the level. Some experence is needed in Unrealed, but if you have none, you're probably better off starting with Unrealed than starting with some of the other world editors out there...
Textures, lights, doors, creatures and after-effects need to be placed in the level.
You can find the levels after a quick search (M:R singleplayer) at: http://fileball.net/ut/
but there are quite a few that have already been completed, this is (as far as I can tell) the maps that aren't being worked on or finished:
05-Couch Fishing = Not Done
07-Smells Like Napalm, Tastes Like Chicken = Not Done
12-Shake Before Using = Not Done
13-Fire!Fire!Fire!Fire = Not Done
14-Colony Ship For Sale, Cheap = Not Done
15-Habe Quiddam = Not Done
17-Pfhor Your Eyes Only = Not Done
18-No Artificial Colors = Not Done
19-Unpfhorgiven = Not Done
20-Two Times Two Equals... = Not Done
22-Eupfhoria = Not Done
23-Pfhoraphobia = Not Done
24-Aint Got Time Pfhor This... = Not Done
26-Try Again = Not Done
The way to use the new objects provided in the M:R files can be found in the manual section of this site, or you can tear someone elses level to bits to see how things work.
It's not as daunting as it might sound - the MMC is very effective, and usually sets the correct orientation & scaling of all the textures. The only time you might have issues is if there is any 5D space in the map, which has caused me a few headaches in the maps I've worked on.
Best of luck, and if you have any questions, drop us a line.
