Gameplay & Survival

In our Early Access Roadmap, we mentioned that electrical systems were one of the key improvements we wanted to bring to the gameplay and survival systems. This update introduces an early version of that with the addition of batteries. Some items now require specific types of batteries to function at full capacity and have an inventory that can be opened to fit batteries of different sizes. Batteries deliver power based on their size, so go experiment with them!

Items

Many of you have been asking for a way to measure distances in-game, and some of you had pretty great suggestions, so we said “sure, let’s do it” and added a step counter item.

The Step Counter tracks steps as long as you carry it with you and has with two modes: total steps and current steps. Reset the counter to track specific distances via current steps, and check your total steps to see the full distance taken.

We also saw a lot of people curious about the surrounding temperature, since the UI only displays body temperature. You can now use the thermometer to check the temperature around you and prepare more effectively.

Seed Sharing via DeepLink URLs

Another update we made was aimed at making sharing generated worlds easier for everyone. Now, whenever you come across a spot worth sharing or simply want to settle a matchup with a friend about who is the quickest explorer, you can share the Seed you’re playing via DeepLinks.

With one click on a URL, they will start in an exact copy of the world you are playing in. The weather is also tied to the Seed, and you can even use DeepLinks to load a custom map design plus a specific Seed number.

Important note: starting a new game via a DeepLink will overwrite your existing save.

Check out our Github for more information on how to create and use DeepLinks: We hope you enjoy the changes, and as always: join us on Discord to share your thoughts, feedback, and cute animal photos.
