Hey, I play the map and it's built really well! It looks just like how I remember way back in the day. Also, the wave system works surprisingly well (except with the occasional zombie spawning in a room I have yet to unlock).

But here is a few constructive criticisms if you are still updating the map if you would like:

1: the beginning is really slow, mainly because of the the really long delay between waves. I feel that the delay could be 30 seconds instead of 60 to speed things up.

2: I know you were probably wanting to do a 1:1 re-creation of the original, but I think it would be exciting if you took some creative choices such as with the pack-a-punches and the items you acquire to keep things interesting and unique

3: The weapons are really basic, I didn't grab every weapon from the Random Box but I felt like I was mostly getting shovels and the occasional helmet. Since you have control of literally everything, it would be nice to have a more variety of weapons such as pre-enchanted weapons and weapons that have special abilities that you can code with command blocks. For example, I made a RPG map and I made lots of special weapons for players to find; such as a sword that applies slowness to hit enemies or a shield that heals when it blocks damage.

4: I wish all the weapons either had an unbreaking effect or just had unbreakable tag because the wooden and stone tools/weapons usually don't last the whole wave and I was usually stuck in the same area because I could not afford to buy any doors because I kept buying the same stone shovel again and again

5: You can definitely do more with splash potions, especially since the player will fight massive hordes of zombies, I see what you did with "grenades", but I think it would be fun to have more options such as wither potions and weakness potions - even if it's deviating from the original COD game

6: This would be a bigger change, but I'm not a fan of using the rotten flesh as currency. Zombies don't always drop them and it's annoying waiting so long for them to process. I would suggest using experience levels because you can use command blocks to remove experience when you open doors

Hopefully you find this helpful and I look forward to playing your other re-creations!

Surprises me people are still into this, even in mc lol. I’ve been spending the whole past week on Nazi zombies in der riese at WaW
