Evaluation

Under A New Sun entered Steam Early Access on November 13, 2023 and remains firmly in active Early Access development. New Horizon Games has maintained a strong and consistent cadence of major updates throughout the game's life: the New Dawn update (v0.8.0, July 21, 2025), the Tech Update (v0.9.0, December 18, 2025), the Building Update (v0.10.0, June 5, 2026), and most recently the Explorer's Update (v0.11.0, August 31, 2026). This represents four major content releases across roughly 13 months, with the most recent arriving just 18 days before today's date. Numerous feature patches and bug fixes have shipped between these milestones as well. On September 18, 2025, the developer published a community-voted roadmap outlining multiple upcoming content categories: Fauna update, Flora & Cooking update, Islands/map expansion, ongoing Story additions, expanded Character Customization, and various quality-of-life improvements. The Tech Update (December 18, 2025) and Building Update (June 5, 2026) subsequently shipped, fulfilling portions of that roadmap. However, the Fauna, Flora & Cooking, Story, Character Customization, and Islands/map expansion categories remain explicitly planned and undelivered. The Explorer's Update (August 31, 2026) itself touched on the Islands/map expansion category (a new island, a new wreck site, procedural underwater world updates), but the September 18, 2025 roadmap described a broader scope for these areas than what shipped in the Explorer's Update, and the developer has not communicated that the roadmap is complete or that development is winding down. Development momentum is clearly ongoing, with active communication and a consistent update cadence continuing through August 2026.

Evidence

Explorer's Update (v0.11.0) shipped with a new island, new wreck site, procedural underwater world, journal system, map markers, and inventory improvements — the most recent major content release.

About this game

The plan was simple - the ship would wake you from your cryocapsule before you arrived at a potential new home. A planet for humanity to start a new life on. But when you awaken, you are already on the ground amongst the wreckage of your ship with no one else in sight. Stranded and surrounded only by debris, you start your journey under an unfamiliar sky.

The planet has a breathable atmosphere, which is a good start. Surprisingly, the area is already filled with a lush flora and fauna — some of which seem familiar, others completely alien. A few of the old seedlings from Earth must have survived the crash somehow, building a new kind of ecosystem.

What happened to the ship? How long have you been frozen in cryo since your arrival? You don't have the answers, but...for now, you have more pressing concerns.

You must find a way to survive and make this foreign planet your new home!

Survive

Face hunger, thirst, weather, and hostile fauna while the days pass by. Treat your wounds and keep your eyes open, some old machines still roam the landscape. The scorching sun above is unforgiving.

Explore

Discover various islands, underwater locations, old wrecks, and more. Find out what happened to your crew, where you are and what went so horribly wrong with your ship.

Craft and build

Harvest the resources of your new surroundings, refine materials and craft new tools. Find your way to the top of the food chain and build yourself a new home!

Sail the sea

Adjust the sails and follow the wind! Just like our ancestors sailed over the seas of our old home to discover new land.

Gather electricity

Scavenge wrecks and whats left of your old ship. Harness the power of nature and generate electricity to power advanced technology's.

Interact with the world

Interact with several different types of workstations in a unique and immersive way to refine resources and take your next step forward. Instead of navigating endless menus, you physically interact in-game with your items.

For example:

• Make cloth on a loom

• Split wood into planks

• Process raw hides into usable leather

• Smelt ore and forge it into tools

• Potter and fire clay into usable objects

...and more!
