Guide

Your first priority should be to find a source of food and water. Depending on the difficulty and game mode, you might begin the game with a few items in your inventory, but they won't last long.

Berries, white mushrooms, and brown mushrooms are fairly common, and are easy to collect. You can also kill crabs and turtles for their meat. (Raw meat is safe to eat, but it's more nutritious if cooked first.)

Most food items also contain some moisture, which will help reduce your thirst, but spring. Avoid drinking salt water (from the ocean); it will actually increase your thirst.

Establishing a Camp
Once you have a decent supply of food, you'll want to craft a hammer and find a good spot for a home base.

To craft a hammer, you'll need one branch and one stone, which can be obtained by punching trees and rocks, respectively. Open your inventory by pressing the C key, click on the stone and the branch so that both are selected, and then click the Craft icon (the yellow plus sign) at the bottom of the screen. You'll be shown a list of items that can be crafted from the selected items.

Once you've crafted a hammer, select it from your inventory and press T to equip it. (You can also press a number key to assign it to a hotkey.) With the hammer equipped, you can right-click to open the building menu.

Don't worry if you don't have all of the necessary items in your inventory—
