Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“As a small indie studio, we value the feedback from you, our players. It is a major part of the development cycle and helps us shape the game into something the majority of you can enjoy. Feedback early in the process is extremely helpful, as doing major changes at a late stage can be virtually impossible.”

Approximately how long will this game be in Early Access?

“Once we go Early Access, we expect to stay this way for approximately a year. The exact time will depend on how fast we can finish implementing remaining features and content, while at the same time dealing with feedback on existing features and content. Promising a specific time that we will stay in Early Access is risky business, we know this, it is common that titles stay in Early Access much longer than intended and ours might not be any different. However, we feel that actually getting to the finish line and fully releasing the title is more important than following arbitrary deadlines. We have always finished.”

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

“During Early Access many things are sure to change, and many of these changes will be the result of community feedback. This could potentially lead to some things being cut and also new things being added. If you would like to affect what stays and what goes, then kindly take part in discussions on Discord and the community discussion for Under a Rock here on Steam. We won’t always be part of the discussions ourselves, otherwise we will not have time to actually make the game, but we will watch them.

These are the additions we currently envision:

  • Additional biomes
  • Additional creatures
  • Additional things to collect, craft and construct
  • Boss fights
  • We would also like to add taming, breeding, and riding during Early Access
  • More optimizations for an even smoother game experience
  • Further enhancements of the dynamic AI

This list will be updated before we enter Early Access as much can change between now and then.”

What is the current state of the Early Access version?

“Early Access is not yet open, and we are still a bit away from this happening. Please have a look at the ‘ABOUT THIS GAME’ section a bit further down on the page for details of the stage we are currently at. Also feel free to ask us questions on Discord and the community forum for Under a Rock here on Steam.”

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

“Price may increase moderately when we release. We will give at least one month notice on any price increase.”

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

“We would love hearing your thoughts. Feel free to share them on our Discord and on the discussion forum here on Steam.”

About This Game

Under a Rock is a procedural open-world survival craft game for 1-10+ players, and is being developed for Windows, Linux, Playstation 5 and Xbox Series X. Explore a primitive but dangerous place with a different evolutionary path; here, wildlife is oversized, Neanderthals still exist, and curses are real.

We are currently in pre-alpha and share regular updates, as they happen, on our Discord. Hope to see you there!


You are an early nineteenth century explorer who has just arrived - or crash-landed is probably a more precise term as your hot air balloon was ripped to pieces by a supernatural storm - in a world lost to history, a hidden world that few can travel to (and from!), a primitive but dangerous place with a different evolutionary path.


The underlying mission is to find out what happened to a previous expedition, lift a curse that lies over the land, and discover a way to escape back home through the supernatural storm with as much treasure, artifacts and native wildlife as you can possibly collect to increase your standing with the Society of Explorers. Apart from this, just have fun exploring, crafting, building, fighting, taming, hunting, surviving, and more.


When you start a new game, a procedural world that is unique to you is created. Each world measures about 64km2 and includes caves and underwater areas to explore. Waterbodies, like lakes and ponds, are not limited to ocean level and can be found at any elevation.

Each world has a seed number that can be shared, and your avatar is not locked to one specific world. You may freely travel between worlds with all of your stats and gear intact.


We want to make Under a Rock more interesting by having dynamic AI and are currently developing an AI engine for this purpose. It allows AI to remember and respond to your actions and the actions of other AI, compete for territory and resources, even construct new bases and defenses. Don’t be surprised if a neighboring clan of Neanderthals stage a raid on your base just because you smell wrong, or a pack of dodos take a liking to you. Different AI factions can grow closer to each other or grow apart as time goes by. Nothing is set in stone and a fresh game with a new world is likely to throw a few surprises.


1-10 players in co-op, but we plan on allowing an experimental mode where the host can set a higher player count. It will require the host to have beefy hardware and a hefty internet connection.


They come in all shapes and sizes, from small to gargantuan, with the latter being a whole biome by itself. Creatures inhabit them, and they rarely like to share the space, or the precious resources found within. Kick them out, claim the space and build your base within, there are no limits. Caves are seamlessly integrated into the landscape, no loading screens.


There are two build modes that can be switched between seamlessly.

  • Default mode, for placing solid constructions directly if you have the necessary resources.
  • Advanced mode, that allows you to plan and prioritize your base construction and for your friends to help build it by inputting the necessary resources. We call this Ghost Building.

Spent hours, days, weeks or even months on building an amazing looking base? Cannot stand the thought of doing all the nitty gritty details again? This is where ghost building truly shines.

Activate the auto-saved blueprint of your base or a manually saved version. Any destroyed base elements, from the largest to the smallest, will show up as ghost elements. All you need to do now is input the necessary resources. Since this is ghost building, any friendlies can also help with speeding up the reconstruction process.

We plan on eventually making it so that construction blueprints can be saved for later use and also be shared with other players. You cannot pack down your base and unpack it later, but you will be able to make blueprints and reuse these at other locations as part of the ghost building system. Use them to quickly establish a campsite, a small outpost, or even a large base provided there is ample space available for placement.

There will be very few rules limiting how and where to build. On the ground, in the trees, inside of caves, even under water. We won't stop you, although the wildlife might try to.


The host will be able to set rules for the server. PvP on/off will be available.


There are several ways. You can host a game directly from your own computer, setup your own dedicated server or by renting a game server in the cloud from one of our partners. Games can be either public or private, and cross-platform will be supported.


It’s a little hard to say. We have finished most of the technology requirements for the procedural generation of the world and for the multiplayer backend. Now we are populating it with visuals and gameplay, and as soon as we feel we have enough content for early access and a stable game that runs well, we will open up. Prior to this, if time permits, we really want to invite as many of you as possible to a period of alpha testing.


We are a small indie game studio, consisting of only five people filling all the necessary roles for making Under a Rock. Being so few keeps us very busy. If we are sometimes slow in answering, this is why.


Full production started on October 8th, 2021. Prior to this we spent a few months thinking shit up and playing around with the idea of doing a procedural world.


Under a Rock is powered by Unreal Engine 5. We are taking full advantage of nanite and lumen, and especially nanite makes it possible to have a procedural open world with amazing view distance and detail.
