Come to think of it, I think I have an idea on Fake Man's level.

Me and a friend of mine got the idea when we built a level in Timesplitters. It was sort of an urban city where you can go down a subway and/or enter a hotel with some rooms to explore.
Ofcourse, some additional graphics would have to be added apart from the Fake Man tileset but what's wrong with some added diversity? XD
The layout is like this (got no pic, so I gotta describe it):
The entire left area is a massive neighborhood area with three or two buildings that you can enter to find some weapons, on the outside there are open windows where players respawn to jump down and ambush other players. There are two exits at the top and bottom right area...
The bottom right area (two doors) takes you down to the subway area that consists of a subway trainyard (is it called that?) with some benches (don't ask me how to make them :S) and a shop to your left side down the flight of stairs, to the left, near the stairs, there is also a passage that takes you to the employee areas, it's basically just a corridor with locked doors (except for one that takes you into the shop) that leads up to the waiting room at the subway.
NOTE: You can fall and die if you jump down to the railway!
The exit is to the far left (if you entered by going down the stairs), a corridor leads to a large waiting room, could contain some more shops akin to some Metro Subway and/or Train Stations, but from there, you can reach another exit from the subway that takes you to...
The topright exit area of the neighbourhood, from the top right, you reach what looks like a small L shaped slum area with tall buildings, it's pretty tight, but you can still be seen from the windows... to the right is there entrance to the hotel, and if you continue pass the turn, you find the exit from the Subway I mentioned before, continuing from that takes you into a very dark slum area were a special weapon is found.
The hotel (could use the tile set from the Transylvania level from Ducktales) consists of a big main hall with a small reception to your right, straight in front of you is a flight of two stairs that takes you into a corridor that goes on from your left, from there are all the rooms, they are all pretty simhilair to each other and got some items and respawn spots, but some of them have open vents that can take you down to the subway area (remember the employee area?) but one room has a fireplace... IT IS AN ILLUSION! You can cross the fire and enter a secret passage that takes you into the room behind one of the windows in the slum area! Here you will find a special weapon.

What do you think of the idea?
