i know this is old and probably not being worked on any more but i just wanted to add somethings that would have been cool to see
1. Being able to scavenge and kill around with npc survivors
2. Better camera angle like a low third person angle so that we could possibly build a two story base
3. A lot more weapons if your not working on that already but if u were you should have already finished them
And that's all I've got
Update:
One last thing is there is a short supply of zombies on ps4 it would be cool to add a bigger map
