Compounds are structures that can be claimed by players. They come with lights and shutters that are controlled by a simple GUI. They are easy-to-use and easy to fortify.
How To Claim A Compound:
To claim a compound, the sign above the door must say, "Claimable Compound", which will allow you to unlock the door by walking into it. This will make the compound your very own.
Once you've claimed the compound, your username will appear on the sign. (Example: Bob's Compound)
Compound upgrades are expected soon.
Compound #2 is considered the worst, due to the number of zombies near the area and the inconvenient slope which allows zombies to easily get in.
