It crashes on launch for me, says something about sound allocation, didn't get the exact error

Do you have campaign or multiplayer installed?

It's because you had a mod loaded, this map doesn't work with mods. I had the same error.

I tried it with a mod loaded, got the same sound allocation error. I re-launched the game,and it shut down COD. Restarted, re-launched the map, got ERROR Server Disconnected - Game session no longer available.

There's definitely a problem with this map, and it doesn't happen to everyone obviously...Maybe if you fix the problem that it has when using a mod, it will work. Just a thought.

This version is intended to not be used with mods, and will never work if you try to load mods with this map. There's enough custom content here that I think you'll enjoy the map as it is thank you. I will wait to see if a mod friendly version should be warrented. But for now, please enjoy the map as I envisioned it.

I have experienced a lot of FPS drops in every open area, that's the only issue I have experienced yet.

I suggest lowering your shadow mapping and turning off volumetrics. Nothing I can do on my end without making the map look worse.

UPDATE 1.01:

Added M19 to the Mystery Box
Removed Hacker (Way too buggy to keep)
Lowered fx resolution on low settings.
If you still experience stuttering please lower your graphic settings and tune accordingly.

Ok I turned off my mod and that did in fact fix my issue (for reference, it was this zombie counter mod https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1109807270)

I crashed on round 40 when I killed a horde with a claymor I think claymores r buggy and cause a crash when u use them a lot

UPDATE 1.03:

Added Bank at the buyable ending
Added Renetti to the box
Performance Optimizations
Adjustments to lighting

UPDATE 1.04:

Reduced file size of user aliases. Attempts to fix sound allocation crash.

There is a bug when u get into later rounds effects like muzzle flash and explosions don't appear, but i'm not sure if thats the game or my pc

UPDATE 1.05

Adjustments to the Renetti in the box.
Added a prop near the teleporter for people having issues with collision.
Replaced the base power switch with Vertesea's. It doesn't change anything in the map.
Upgraded Makarov has been buffed.
Added a duck to the map. Not kidding, I dare you to find it.

UPDATE 1.06

Minor Adjustments to Lighting
Fixed a Model not appearing in the map
