Perfect!

Hello friend, thanks for the map it's really cool.
I ran into two minor issues playing it, and I have one idea for improvement.

I wanted to tell you that one of the weapon pickups is bugged and cannot be picked up :

Maybe this can be solved by moving the weapon spawn slightly? I am not a map maker so I would not know.

Another thing. The player can hide from husk fireballs very easily because the zeds are on a slope and the player is on level ground. Standing back a bit means the fireball crashes into the slope. I thought of two fixes:
1) You could try to slope the players platform as well, but I imagine that must be pretty hard from a geometry perspective.
2) You could invert the sloped corridors so that the zeds walk down towards you.

Lastly, here is my idea to improve the map.
Playing Commando, I found that I really had to select my targets in order to stay alive. Shooting bloats and cysts does not make a lot of sense because gorefasts, stalkers and crawlers are much faster and get to your defensive position quickly. However, it was not always possible to prioritize certain targets as weaker zeds would block my view.

If you would turn the linear slope into a gradually increasing slope (so flat at the bottem, then getting increasingly steeper towards the players platform), I would be able to look over cysts heads at zeds more deserving of my attention.

Also, if you implemented this, the player would be required to use more vertical mouse movement instead of mostly horizontal.

For these two reasons I strongly believe that making this change would make the map more skill based and more interesting.

I hope you read this! If so, thanks for reading!
If you agree on the points I made and if you'd be kind enough to work on them, please tell me. I would be very excited.
