Nice map Icarus, it's been a lot of fun playing the betas.
I have some suggestions for you, so first of all
Stairs
Add clipping to
ALL your stairs. You have a decent amount of stairs in your map and
none of them have clipping.
Like this:
It helps with continuity and you will be able to jump while running up the stairs instead of getting a vertical fail jump. (And Valve uses it on all their stairs)
Wall clipping
Take a look at this picture.
There are many places for the player to accidentily get "caught" while walking. So to enhance continuity, you should use sloped playerclip brushes to eliminate 90 degree angles.
For example:
It's ideal to prevent the player from getting caught in the surrounding geometry.
You can use another playerclip in this example:
You should be using these ALL over your map.
Abusive demoman
At point C, a demoman can land on all those metal beams up there. You can either make a tall playerclip roofs on all the beams, or like cp_steel, you can use a trigger_push on the top of these to push people off.. Or just leave it
Overlaps and Misaligns
These are probably just small things you overlooked, but just in case you don't know, misaligned and overlapping brushes are VERY suboptimal. (Unless they are func_detail, then it's not so bad.)
In this staircase you have a set of stairs completely overlapping eachother.
Textures
Be sure to recheck all your texture, that they are properly aligned.
Lastly, just a cool spot in your map:
You can get up to those rafters with engineer in 60 seconds from when the game starts. But by then the setup timer is over, and you still got a dispenser and a sentry on the to-do list. If you can pull it off though, it's kickass
btw I love the new building you added. Keep up the great work.
