What the developers have to say:

Why Early Access?

“We have chosen Early Access to allow players to experience the core fun of the game as soon as possible. This does not mean the current version is incomplete – it represents a significant investment of our time and effort and is already quite feature-rich. However, we firmly believe that determining whether a game is truly "fun" and identifying those hard-to-find issues requires verification and polishing together with our players. Community involvement is crucial for the final optimization and expansion of the game, and we look forward to shaping an outstanding experience with everyone.”

Approximately how long will this game be in Early Access?

“The Early Access phase is expected to last between 12 and 24 months. We adhere to the principle of wanting the full release to deliver astounding content to our players. While maintaining quality, we will develop at full efficiency to create as much engaging content as possible. Conditions permitting, we hope to reach the full release swiftly, but never at the expense of quality.”

How is the full version planned to differ from the Early Access version?

“We plan to add substantial expanded content for the full version, such as more expansive maps, a greater variety of refined items and models, richer interactable or combat AI – essentially, any idea that could make the game more interesting is under consideration. Furthermore, we will continuously optimize game balance and user experience based on community feedback. Please note that specific content may be adjusted according to development progress, and we will keep the community updated on our plans promptly.”

What is the current state of the Early Access version?

“After 24 months of development, the current Early Access version features a solid foundation. All core systems shown in the promotional materials are implemented, including building, resource gathering (chopping trees, mining), fishing, combat, inventory management, cooking, animal husbandry, farming, a day/night cycle, and multiple map areas. Moving forward, our focus will be entirely on detail optimization, performance enhancements, and delivering regular updates to fix issues, and introduce new content and systems.”

Will the game be priced differently during and after Early Access?

“We are committed to developing this game into a finely-crafted title that receives long-term support. For the full release, we aim to deliver a deeply engaging, stable, and satisfying experience. Therefore, we plan to moderately increase the price upon the full release to reflect the added content and features. All players who purchase the game during Early Access will automatically receive all future updates at no additional cost.”

How are you planning on involving the Community in your development process?

“We place immense value on community feedback and plan to maintain close communication with players through various channels, such as:

Regularly collecting bug reports and suggestions on the Steam Community forums, official Discord, and social media.

Sharing development progress and future plans publicly through developer blogs.

Inviting select players to participate in testing before major updates to help us identify issues early.
Player input will directly influence our development priorities and adjustment directions. We eagerly anticipate working hand-in-hand with the community to polish this game together!”

About This Game

Oxygen Train is an open-world survival and construction train game. You wake up in a world severely lacking oxygen for unknown reasons, and start from scratch building your own train—chopping trees, mining, gathering resources to expand and upgrade your unique train. Ensure your survival through planting, fishing, farming, exploration, combat, and more, while gradually building a train kingdom. Supports 1–8 players online co-op.

Oxygen
In this anoxic world, you must constantly search for oxygen sources or unlock advanced technologies to solve the oxygen problem entirely. As you progress, you can ensure that all players, plants, and animals on the train are free from oxygen deprivation.

Cooperation
Supports 1-8 player co-op. Join a friend's room for a fishing competition? Race them to the top of a mountain? Steal the train and leave your friends chasing after you? Drink all the water on board and leave your friends passing out from thirst? It's all up to you.

Exploration & Collection
Explore snowfields, grasslands, deserts, islands, berry forests, farmlands, volcanoes, and other unique terrains. Different areas contain special items for various purposes. Collect these exotic resources to aid life and operations on your train. Always be wary of hostile creature attacks.

Cooking
Ingredients can be eaten raw, grilled, or cooked. Special ingredients can undergo unique processing—for example, fresh fish caught or farmed can be sliced at the fish cutting station to make sashimi. Cooking requires finding recipes for corresponding ingredients. Different cooked foods provide various buffs.

Planting
Collect strange seeds or vegetable seeds and plant them in soil pots of different levels. Care for your plants diligently to reap a bountiful harvest. You can even plant towering trees on your train—a truly satisfying achievement.

Fishing
Unlock fishing rods to conquer lakes, oases, and oceans. Fish for different species in various locations. Not only can you make sashimi or cook fish dishes, but you can also keep rare fish for display and breeding.

Construction
Gather and fire various building materials to transform your train into a rolling kingdom. Build all kinds of carriages, each serving different purposes—it's a true test of your design inspiration. Continuously upgrade train materials and build defenses to withstand more attacks.

Farming
Nothing feels safer than the contrast between a disaster-ravaged world outside and the warm glow of a chicken coop inside your train. Not only can you raise chickens for eggs and breed fish, but they also provide companionship in this lonely, post-apocalyptic world. More farming system content awaits your discovery.

Combat
The anoxic apocalypse brings greater dangers. You must not only guard against animal attacks but also the barbaric acts of oxygen bandits. Unlock clothing and armor, craft more powerful weapons, and fight back. Upgrade cannons, heavy crossbows, and other large vehicle-mounted weapons to ensure the safety of your entire train kingdom.

Research
At the research table, you can unlock new technologies and items. Simply gather and process the required materials to unlock them. Continuously research better technologies to make life on your train more convenient, even achieving light automation.

Entertainment
Life on the train can get dull. Then your friend suddenly plays a moving tune on a makeshift piano. You pick up a guitar and join in. Someone beats a makeshift drum, someone sings—and suddenly, life feels a little brighter.

Trading
Not all oxygen bandits are purely evil. Bandit merchants often appear on the map—sometimes in a small shop, sometimes in the most unexpected places. You can trade rare resources with them for Oxygen Coins, the currency of this post-apocalyptic world, which can be used to buy various supplies. Rumor has it that someone spotted a mysterious merchant riding a camel in the desert, but I've never seen them myself.

AI Generated Content Disclosure

The developers describe how their game uses AI Generated Content like this:

In terms of game content, although our team excels at music creation and painting—with skills in music arrangement and original illustration—these roles are currently filled by programmers and modelers. Therefore, we want to devote more energy to the development of core game content. As a result, we have used AI technology for some object icons, promotional images, and background music. However, we hope to create original illustrations, original music arrangements, and more in the future as the game is further promoted.
