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.
