Okay first off I have to admit that I'm not a big fan of small maps like this one because of the short distances and limited space but I know this is a trend among fy-maps so I'm going disregard that opinion, after all it offers some fast game play.

Pros:

Cons:

• The 3Dskybox is half the map and contribute a lot to the environment and the map itself.
  It's usually not a big deal but when you have so much vertical game play as this map offers you see just as much of the 3dskybox as of the map itself.
  The current 3dskybox offers a plane green field with some scattered industrial buildings and a huge error sign (Probably caused by a missing model) and make the map area feel really out of place.
  
• The smoke and steam effects in the middle area looks cool but should always be used with a pinch of salt.
  As it is right now it's a little too dense and makes it hard to see your opponent, even if it's meant to be it's very frustrating.
  The many overlapping smoke clouds also causes some fpsdrops while walking around the middle area.
  
  
• One of the Env_steam entities seen from CT's spawn flicker when you walk under it.
  
• The ladder on the T's side is hard to spot due to the dark texture. (The longer one of the ladders)
  
• I tried playing this map with a few bots, it worked better than expected but the CT's had some problems to get up on the first ramp.
  Even if the map isn't supposed to be played with bots it's always nice to have it compatible.
  

Improvements:

• Look over the 3dskybox, add some more buildings closer to the main area to continue of the industrial theme and make the transition between "map" and "3dskybox" less noticeable.
  Maybe add some tele cables and give the terrain some work.
  
• Reduce the smoke/steam effects in the middle area, lower the density or try to reduce the emitters to bring up the frame rates and give a clearer view.
  
• If this emitter still flicker after you've reduced the other particle effects try to bring the entity down a few entities from the brush above it.
  
• Change the drawtexture from 0 to 1 on the dark ladder on the T's side, to give a better contrast from the wall.
  
• To make the map fully playable with bots, you can create a custom navigation (.nav) file for the bots, (You probably know how to do it, but if not :) by using a set of console commands to edit or create a new navigation mesh.

  Final Notes:

  Overall a nice Fight Yard map over the average degree.
  As Beta1 it's totally acceptable.
  If you can, please try to avoid using "invisible walls" (clip brushes etc) to block the player in, it adds to the perfection if you're blocked by visible reasons.
  And sorry for writing so much - I felt for it..
  
  Cheers!
