Hey there! I suggest adding the opportunity to restore old fences around the house or build new ones if the old fence was not there or was broken. I saw small protection in vidoe on kikstarter. There was only barbed wire there. I think it's not enaugh. It would be cool if we can build high-grade fence. I remember about never free building. And I don't tell about building a fence everywhere you want. No. Only restoration of the fence where it was. Or make some rulles for building fence: where, what, how. Zombies can break the fence or to knock it down with the pressure of a crowd zombies. Attack on the house can be divided into two levels. The first level is a fence, the second level is the house itself. To build a fence, you need to cut down trees. Make strong poles and boards (as in the trailer). By protecting the house with a fence you can plant a small garden on the territory. More bigger and more better than potted plants in the house. But it will be more at risk if the zombies break the fence. And this will require more care. More risk, more work, but if successful, a huge crop.
