What the developers have to say:

Why Early Access?

“We want to put the game into the players’ hands as soon as possible and build the future of it with them.
Space, and especially Mars, has always generated great enthusiasm among gamers. As we want ROKH to be one of the most incredible online persistent experience, we can’t achieve that without the players’ input & feedback. On our side, this means strong support, fine-tuning existing features, frequent updates, and crazy upcoming features for our gameplay.
It allows us also to collect the fund to finalize the development and reach our high expectations for the game.”

Approximately how long will this game be in Early Access?

“Based on our production calendar estimation, we aim to release the game in its final state in maximum 12 months following the Early Access release. But we will of course continue to update it, adding new content and mechanics after that.”

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

“The final version of the game will have more content and features. Our most ambitious upcoming features are a combat system, a complete in-game programming & hacking systems, craftable vehicles and a food growth system. These features should be added in the first major updates of the game.”

What is the current state of the Early Access version?

“We’re currently entering our alpha phase. For Early Access release, players will enjoy a persistent multiplayer experience including ROKH’s major gameplay pillars: exploration on a huge Mars open-world, harvesting resources, deep modular crafting & building systems.”

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

“According to the current scope we aim less than $30. Depending on the scope after Early Access and the size of the team to deliver it, we might slightly adjust the price.”

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

“We consider that ensuring a strong bound between players and our team is a strategic point for the game’s future. We will establish effective tools on several channels to create direct links between players, developers and community managers. Our objective is to provide a great reactivity in terms of bug report, community feedback and features optimization. We also aim for a complete integration within Steam Workshop in future updates.”

Week 8: New update is live! Discover our new streamlined crafting, improved mining and more!

Hello Colonists!

We are happy to announce that our newest patch is now live, we are currently wiping and updating the servers. They should be up in the next hour. Get ready to (re)discover the Red Planet!

As presented in previous devblogs, we are confident that this patch (biggest since our release) will change in a better way how you are experiencing the game right now.

With a streamlined crafting, you’ll reach the building stage earlier, allowing you to concentrate on optimizing the perfect Martian base with your friends.

The crafting UI has been greatly improved for a smoother experience too.
Unfortunately, these changes require to wipe all the official servers as most of the crafting recipes have been modified. If you own a private server, you will have to wipe it as well to play with this updated version of the game.

While mining and extracting raw resources, you will get more information (quantity left in a node, name of the resource, level of pickaxe required). By pairing that with the highlighted stats in the crafting UI, be sure to make better crafting choices.

A lot of new animations have been added, for a more dynamic player experience while you are exploring the Red Planet. Community objectives have been reworked, we hope they drive players to collaborate together on each server!

Finally, a lot of fixes have been added in this patch. Feel free to share your comments, feedback, bug reports as we are monitoring daily the Steam forums, our Official Discord Channel, as well as our social medias (Facebook and Twitter).

If you report a bug, please follow the instructions provided on the Steam forums ( How to report a bug ) or on Discord, it helps us debug in a more effective way and helps also our moderators to relay the information! (Big shout out to them: Beaker86, DoctorPelusa and HolyAvengerOne, thanks for your awesome help!). Thanks also to all players who played a bit of the experimental build in the previous days, and provided us really valuable feedback.

Finally, given the many changes and fixes provided with this patch, many threads from the Steam forums will be no longer relevant, expect some of them to be archived.

But enough of chitchat, here are the patch notes 😊

Week 7: Laying the foundation for our big patch next week!

Hey Colonists,

We hope everything is doing well on the Red Planet! Since last week announcement we have noticed some strong reactions to the crafting streamlining patch that we will be pushed live next week. From what we have read, everyone praises the fact that this will greatly reduce the tool switching actions while crafting. Some of you have expressed concerns about losing the depth of crafting with the recipes simplification. We wanted to repeat here that our team has designed this simplification in a great way: it removes the shallow repetitive crafting actions. We are confident this will help players to focus on strategic choices related to the resources and parts stats to optimize their crafting results in a great way.

Remember also this is only the V1 of the rework of the crafting system and we are already designing a V2 which is far more ambitious. For example, it will not rely anymore on the tools equipped in your toolbelt, but on all your backpack. It will also display each version of the same tool, so you can choose between the low quality and high-quality tools. This will allow players to manage the durability damages in a really efficient way.

Finally, remember that we are planning a server wipe for this patch. All official servers will be wiped to update the game. Most of the items recipes have been changed, so a server wipe is required. We will communicate a precise date and hours for the patch later next week.

Community Creations

We had some really cool creations from the community since last week!

Firstly, let’s present you the 4th of July Contest Winner!

Lukas did a really great job with his base with this beautiful US flag integrated in the whole structure! Especially the blue part of the flag replaced by windows, that’s a clever move 😉!
Congratulations to him, he wins 3 steam keys for his friends!

Apart the 4th of July contest, we have seen some other really cool bases too:
Jonas’s base looks really cool:

As well as the one from SkankinMoe:

Finally, Bustaeddy knows how to mark his territory ^^

Development Follow-up

Unfortunately, we were not able to push live a hotfix this week. The team is indeed fully committed for the next patch with the crafting streamlining and is also debugging this future build at the same time. We hope you understand that hot fixing is always problematic, especially when you already have an ambitious build ahead of the live one.
With the size of the current team, and the ambitions we have for the next patch (in terms of features improvement or debugging), we cannot handle both at the same time.
Right now, most of the big bugs we are addressing are related to stability in the new build. So far, the biggest red flag bugs from the current live version that were causing crashes have been addressed in the new build.
We have also narrowed down some issues with the pressure system. Thanks to your report we have identified that gas flows inconsistently through pipe networks. It is more prevalent in networks connected to a gas reclaimer or a pump. A simple setup with a storage tank should work though.
Also, we do not forget to solve ASAP the connection issues. This is a time-out issue caused by several problems, and we are solving them one by one. We thank you again for your patience.

Don’t forget to join our Official Discord for report and feedback ( Join here, and to continue the information flow on our Steam Forums. We thank again for this continuous info which helps us a lot to improve the game!
See you soon,

About This Game

ROKH is a futuristic survival game, deeply rooted in scientific and realistic anticipation.

Players will have to work together to overcome the many threats they will have to face on planet Mars.

Created by team members behind Thief, Half Life 2, Dishonored, Age of Conan and Assassin’s Creed, ROKH is an adaptive survival game that is built on top of Unreal Engine 4 and deeply rooted in science. Players will land on Mars to find that the previously developed human colonies have been decimated and they must work together to overcome and survive. ROKH features a persistent world and co-op multiplayer.

In ROKH, players explore the Martian landscape as they scavenge through the deserted structures to gather the resources they need in order to survive. With few blueprints, they must use their ingenuity to create tools from a variety of materials and construct their own encampments with no design limitations - giving new meaning to “Assembly Required.”

ROKH is a complete immersion into a cold and dry land that harbors a wealth of resources to extract and exploit. Players will explore Mars, paving the way for settlers to come, as Earth’s resources are tapped and the planet is dying. Mars is hostile and joining forces with friends increases efficiency and invites trade and barter to develop a habitable, yet, customized ecosystem. ROKH is a mix of crafting, survival and exploration with an overarching story, that allows to freeform and build a colony how they want.

Early Access Key Features

ROKH features tile-based assembly inviting you to design and construct your habitat the way you want. Build on your own or work with others to create a fully customized, massive Martian colony. Clever builders will ensure their structures can support future add-ons to maximize resources.

Each and every one of your moves serves one goal: survive! You will need oxygen, food and water, and to protect yourself from heat, cold, radiation and injury. While Mars offers some accessible resources, you will need to be adaptive and creative to properly develop your colony.

Through Unreal Engine 4’s visual capabilities, you will explore the wonders of the red planet. From majestic dunes, biomes, crash sites, abandoned bases and frightening and deep valleys, you will visit a variety locations to find life-saving resources and uncover the mysterious demise of the first colonists. Mars is deadly and being outside on a frozen night or stuck in a sandstorm can lead to fatal results.

Instead of classic blueprints, ROKH’s crafting system is based on modularity. Devices, tools and weapons are craftable and customizable, but must also serve your needs. Some crafted devices can be socketed into your walls to automate tasks, provide heavier defense systems, increase survivability, provide creature comforts and much more.

Upcoming Key Features

  • Combat system
  • Completely craftable vehicles
  • In-game programming system
  • Hacking system
  • Deep space suit upgrading system
