Have a look at the packaging, http://www.quadropolis.us/node/226. On OSX, the zip contents were in a hidden file, a minor inconvenience for me, but other users may not have any clue what to do.

Pretty good for a first map, but here are some various criticisms:

* Some areas, such as the flag rooms, are too low, every time a player jumps they hit the ceiling.

* The weapons / powerups are all clustered together. For example, the top of the map has 5 rifle rounds and the bottom middle room has a yellow armor, 2 health packs, 4 shotgun shells, and 4 machine gun bullet packs. Players should be rewarded for venturing into the more dangerous center areas of the map, but this is a bit much. (That is not even counting those two 'secret' rooms with 2 rockets apiece)

* There are not enough player starts, two for each side. This will lead to a lot of spamming.

* The texturing is not very good. Some textures, such as the one used on the two hanging structure's support beams, do not fit at all with the geometry or the map's theme.

* The layout in general is not that great either. Most significantly, there are too many spots for campers and for other people to exploit the level design. The rest of the map seems to create a few concentrated choke points, which can be a good thing on a map, but here I felt like that was all there was. There are basically two intended ways to reach the flag, each of which are mirrored on either side.

* This last one is more subjective, but the map did not feel like it ever was a factory or industrial structure. Simply put, it had no history, something I usually like to see on maps such as this.

oh...it would be nice, if u rename this map! There is already a map called "industry", made by me and MisantropX, here on quadro. THX!

hi, i hear all the poor texturing comments, though, unfortunately, i have no faith whatsoever in my ability for aesthetics, i will probably have to work with someone else on that.
stuff i tried to fix (thanks to the comments)

0 I renamed the map to ironically, bigfloatingrock.
0 I got rid of or moved a couple of the ammo boxes from the middle
0 I added another chute to the top because i thought it would be good to have one going directly into the rocket nest
0 I redesigned the top level, though unfortunately i redesigned it to more metal/white square things. (everything else i tried just looked poor to me)
0 I raised the roof in the flag boxes
0 The one-way sniper boxes, because i put a row of one blocks instead of two down the middle of the map, were off center, so i just replaced them with clip boxes.
0 I added pathways, albeit small cumbersome ones, around the grenade chute area.

I think that's it
thanks for the comments.

sorry but IMO this map has absolutely no flow. I can't even sense where to go after respawn..

omg

Aspiring Level designer often create 2 major mistakes

*The layout is too small
*The light too "hard"

Never give someone a chance to camp!, not directly..
Make your lights a bit softer and dont mix them that much.
use 2 major colors and give the map you are making an emotion.

the difference between us humans and robots are that we can create and experience emotions.
put emotions in maps!

best example is niebs hallo,
he used purple and blue tones for textures and lights to make the map spooky/creepy
and he used vertical "lines" to make the buildings look more epic

and also use clichés, like in the way that what is the first thing you think about when you hear the word "creepy".. nieb for example made a cemetary additionally and a creepy underground ;)

in that case he tried to make the map feel cold..

Level design is much more then putting random random cubes and give a layout.
level design is an artistical way to make 3D worlds!,
I always try to make the player feel something when playing in my maps.. except "wow, what a weird map!"
tempest for example should feel a bit cold and a bit creepy, you can hear a storm far away. and the fans which keep the factory still alive.
make your map living.. not just a static object..

I know thats hard in Sauerbraten, but there are ways to make your map living.

Also, dont forget surroundings. which make the map bigger and let the player believe there is more then just the layout playing on it. like its a whole world..
