Living Dead

Your game is amazing and the code is well written
It would be great if you started working on the following features

1- matchmaking system where 4 teams of 4 players can join the map

- then after killing zombies, collecting items, teams can kill each other and steal their items that they have collected as well

- all items should be in a temp state where it's stored on the server memory

- once a team reaches a safe zone like a bunker or a chopper then the team or player can extract successfully. and then the items should be stored in a database on the server. In a storage for this player.

2- then player can upgrade their armor, weapons or clothes from collected items.

3- players can sell these items in a simple database exchanger between players (bid system).

That's all, a simple 3 featuers if they were implemented, then your game will be more like extraction type game and amazingly more fun than it's now.
