! materials/rp_subtransit/facts.txtRP_SUBTRANSIT FACT FILE (YOU FOUND THIS CONGRATS)
This is completly pointless, I had too much free time so I wrote this.

- You found this because you either nocliped or entered the unlock code
- Originally map was called rp_subway
- First map prototype might be still available here: http://myfileplanet.narod.ru/subway_test.rar
- All textures were done in photoshop
- You did not see this:
Dimension rift - secret place which teleports you to desert with only few buildings which are enterable (panel buildings, like 10 floors high). This was 87% done until I encountered too much vertexes error. You might still see it someday somewhere. (http://myfileplanet.narod.ru/awww.JPG)
Miles and miles of tunnels - still have them somewhere, won't compile even as single map (too much brushsides)
Elevator in hangar - Never worked fine, got stripped :(
2 more industrial levels - The one which was in early demos, and the one never released. Too much verts. Bad Valve :( First is 90% done, second is 30% done.
Exploding reactor core - Sorry, its bad (server usually ends messed up) so *snip* ;)
Train construction - Phailed, it was boring and buggy
All Those Misc Companies like MelonicCorp. - BRUSHSIDES >8(
Secret trains - look up miles of tunnels
TCS (train control system) - Great thing, bad valve. Result = messed up. There is still tcs module somewhere on the map.
Traffic signs - Stupid
Traffic lights - Look up TCS, same basis
Surface - Got 35% completed, but when I added it... Brushsides :(
ManyMoreStuffIForgot (MMSIF) - Brushsides.

- First trains had problems and could not reach even small speeds. Derailed.
- First trains were so shaky that people got killed almost all time.
- Cab design didn't change over the time
- Secret codes would be entered via keypad in office sector
- The white-building-sector was meant to be office sector, but it turned inside out eventually
- If valve makes new version of BSP file format which supports more things in 1 map, I will re-make this map into original planned size (oh gods it will be beautiful!)
- Thanks to The Pro for moral support while making this map, and buying GMOD10 for me
- If map would be made as it was planned (original size) it would be something like 700mb BSP, would take lots of ram, and would not lag as expected. You would need some 10 minutes to make your way from first level to the end. Total tunnel length might be well over 80km.
- While writing this thing I understood the need of limit. Todays computers just not have enough ram to store that while in-game :(

Bye,

STATION 606 SECRET: AT THE SECOND TOWN WITH MARKET AND SHOPS:
