Nice one. Fun to play.
I like the environment and surprise combat
My playthrough: https://youtu.be/KsCKpFcHC0g

My play-through ----> https://youtu.be/K6vIFeLIt6I

considering it was your first map, that was quiet good

A lot to love in this combat-focused map. My playthru and feedback here: https://youtu.be/ipZsVMNyFYw

good

Awesome map!

(cont.)
-A lot of door with handles that dont open. If its a locked door connecting two rooms i can kinda understand that but if a door leads nowhere it'd be nice to put a knobless door there.
-The second fabricator seems a bit useless as theres only like 4 more enemies after it.
-I spent a good couple minutes trying to figure out what to do in the room with the second fabricator, the button on the door doesnt really stand out. Try putting a light above it or maybe some ammo or resin under it, or both.

Thats it thats all im done im sorry. id love to see more from you!

Very fun map, thoroughly enjoyed it! Now for an entire essay of critiques and stuff.

-You can get to the end and also out of bounds by squeezing through the containers, dont know if that was intentional or not but its always fun trying to get out of bounds.
-The lighting outside seemed a bit off, like its a cloudy day but its hella sunny? Not actually bad just thought it was weird.
-If you're going to put your player in the direct sight of 10 combine like in the first combat scenario, you should also let your player immediately see some obvious cover too. For example a box on top of the shipping containers, or a large stack of boxes you can see on the ground before they get a chance of shooting you.
-Very generous with resin, maybe a bit too much. I find like 3 pucks of resin looking through cabinets and then over in the corner there's like a pile of 40. Spread them out a bit more, find or make interesting hiding spots for the 5 stacks.

Neat map! Lots and lots of grenades. here's my run:

Disregard my last comment. It appears that the Vulkan integration in Alyx is still in an experimental state and is what was causing it to crash. It works now that I've switched back.

Your headcrab canisters seem to crash my game the second they blow up the boxes at the beginning.

it was good, but the combine shell for me was very freaking loud. it scared me so bad

Really good map!
