First of all, could we have a sticky thread for suggestions (And also bugs, like ApocalypticNinja said)? I would give some ideas but I'd probably end up spamming the forums and Id rather not do that.
Also, here are the questions.

In the future of the game, will we be able to send people we rescued out to gather resources or food? Will we also be able to have people not being used by towers come out of the home building and defend against the zombie hordes? (and will new NPCs be added?)

Hey MrKrabs,

Yea I'm adding a dedicated sticky post for bugs and suggestions now, definitely been playing with the idea of having the saved survivors each do a specific task for the camp, The survivors all defending the camp will take a bit of work with the AI so a few things will come first before such big systems, Lots of new NPCs and Playable Survivors coming soon,

Stay Tuned!, thanks for all the feedback really appreciated,

Rafi
