I'm going to get started on the models and textures for the map, so I'll be working in Maya and Photoshop a lot more than Hammer for the rest of this project.
This is gonna be great!
I'll have a look at alpha2.
[edit]
I played it with another player (1on1 isn't what this map was made for I supposed but it gave me a feel).
Generally, I love this map. I love the layout, flow, connectivity. Everything you can see yet.
This may not be accurate for larger games but I found that there are very few big health kits which can get annoying and the RPG is to dominant at the cliff.
One more minor thing: I believe the windows you can shoot and jump though should be player-height. You get stuck in a duck position for 1-2 seconds if you don't get a clean duck-jump which is a little bit annoying.
Also please try to avoid placing physics props like weapons or ammo. I've seen this so often and it's really hard to not clutter the map but right now there's too little trash and gg-ammo lying around. It should be much denser and not only in the corners all the time, so you can get a quick grab. I missed the gg action.
Except for that: Perfection.
