What would be interesting would be to add 3 news security systems :
the idea i suggest would be a fog machine, that can generate fog , raider / zombie would see nothing / have a reduced vision , that would be interesting to add it in a base , so if you are raided, there would be smoke everywhere and the raider would not see where he go, it could also be used against zombies to be more discret :
what would this system need :
electricity
water ( i don’t know how fog machines work but i guess it use water )
It’s a bit on the useless side but I’d actually quite enjoy for fog machines to be in the game as a larger, more stationary and permanent, as well as toggleable version of a smoke grenade.
