Upgrade your base

[noob from Poland 3]

1. The ability to build not a large gate, but a gate in a small door for one person
2. Connect the walls with wire to increase strength. For example: One wall has 100% demand, if you put another wall nearby and connect them with wire, then both walls will have (roughly) 150% strength. And if on both sides of one wall put on one wall and fasten everything with wire, then the wall in the center will have 200% strength. You can fasten up to three walls at the same time.
3. The wall cannot be broken while it has barbed wire
4. When someone breaks a wall, zombies come running within earshot. Increase hearing radius
5. Barking the iron wall, the ax breaks quickly. But it can be broken with a crowbar and a sledgehammer and they will be stronger than an ax
6. Stretch marks with grains or with something that makes a loud noise (noise attracts zombies)
7. Padlock barn lock. The key to each lock is personal and cannot be opened / closed without a key. But you can open / close the master key. Lock is very durable hard to break.
