SafeBase

Build yourself a "SafeBase Forcefield" directly from level 5. You can place it anywhere, and it will protect your base from wild animals and enemy players. After placing the shield, hold down the E key (while looking at the shield), go to "Radius Options," and select "Increase to Maximum Radius 10x." Then, you can activate it with the E key (activate barrier), and it will expand to its maximum size. The shield can only be placed once and is solely for the protection of your main base on "The Island."
