- Added a train, which moves in a loop. For now, it uses a model from CS:S as a placeholder;
- Added a second floor, for now without furniture (can't figure out what are these red things), AI nodes, and nav mesh.

- Made tunnels even longer;
- Made walls of dark parts of tunnels out of cobblestone;
- Made outer stairs;
- Optimized skybox so the map would work better with the Top Down third-person camera from View Extension addon;
- Updated screenshots to represent the current version of the map. (but not the thumbnails =P)

- Expanded tunnels;
- Tunnel floor and walls now have a cobblestone texture;
- Added urinals in the bathroom.

Initial upload to Steam Workshop.
