From the text file:

This is a smaller map fit for 4-10 players. More can fit in, of course. There's enough spawn points for everyone.

There's a top level which is a small city arena area, two sets of stairs on opposite sides lead down to a lower level that is a small subway station with a working train that rolls through the station every 15-20 seconds or so unless you press the button in the booth to turn it off. The train pushes the player into a forcefield causing death.

The architechture for the subway station is loosely, very loosely, based on a station in Montreal that I spent about 5 minutes in and can't remember the name of it. But it looked real cool.

Secrets: You can phys-jump onto the roof of the center building, there's a crossbow and two armor batteries up there. Best way to do it is to use the radiator.

Weapon list:
Combine Machine Gun - 1
Crossbow - 2
Magnum - 2
Rocket Launcher - 1
Shotgun - 3

Any weapon that you start with is not laying around in the level, but there is plenty ammo.

Enjoy.
