What the developers have to say:

Why Early Access?

“Osiris: New Dawn is a really big, ambitious game and we are a very small team. Gathering feedback from a larger base of players will help us understand what's working, what needs improvement and, most importantly, make sure the game is enjoyable on every level.”

Approximately how long will this game be in Early Access?

“The release date for any game is always a moving target. With Osiris we not only want to build a ton of content and features into the game and planets, we also want to build out a fully realized Solar System that can be visited with each planet providing a unique experience for version 1.0. We estimate it will take about a year to get there.”

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

“We've built Osiris to have a great technical framework which will allow us to continually add new creatures, game modes and visual elements – we want to stuff every possible inch of coolness into this space adventure. Our plan is to provide consistent major updates throughout Early Access as well as create an entire Solar System to visit before the full version is released. We plan to build upon the current set of core gameplay mechanics and expand them towards the full version of the game.”

What is the current state of the Early Access version?

“Traditionally, publishers we've worked with define Alpha as “content complete” and Beta as “feature complete,” with Gold referring to a full release candidate. We'd currently place ourselves between Alpha and Beta: call it "early Beta" if you will. The game currently has fully featured first and third person perspectives, crafting and survival mechanics, ranged and melee weapons, fully realized alien AI, several vehicles, a vast planet to explore and MULTIPLAYER!

We strive for each feature and piece of content in the game to perform solidly and look as good as possible.”

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

“We feel the price will increase after Early Access due to the increased amount of additional content. With that in mind, we want to reward those who are with us from the beginning by offering them a lower price initially.”

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

“We want to create an amazing near-future, Sci-Fi experience and would like regular constructive feedback from the community on the current game in addition to new feature and content requests. This will enable us to prioritize them in our development cycle. We plan on doing this by being active in the Steam forums and social media in addition to podcast episodes focused on game design in “The Game Design Dojo Podcast.” We're also looking into other channels of communication and will update the community when those become available.”

March Update and PAX East

As you may know, March is a very busy month for the Osiris team! Fresh from our amazing showcase at GDC (many thanks to the lovely people at Unity), we impressed a lot of people and heard some very kind words in regards to all the great new visual upgrades we’re delivering in our next major update.

And that brings us to some updated info regarding the upcoming patch; there’s no rest for the weary as we go straight from GDC to PAX East this weekend. While we’ve been squeezing as much time as possible to work on the patch, the reality is that we definitely need more. PAX East is an important convention event that we need to be at to meet with our core audience. We simply don’t have enough time to get the update to the point where we’re excited to deliver it to players. We want to make sure we deliver the quality you come to expect from us, and right now we don’t feel absolutely comfortable delivering on that quality by our original date of March 10th.

That said, we ARE confident that we’ll be delivering this next patch later in March and we believe the wait will be worth it when you feast your eyes on all the huge graphical improvements (some of which can be seen on the MadeWithUnity blog that you can read here: ). Weather and lens effects, volumetric clouds, ambient occlusion, depth of field, light scatter, screen space ambient shadowing… the difference visually will be night and day for the game!

Of course, we’re working on a lot of new content as well, and the next couple of weeks should give us enough time to finalize some new features we’ve been waiting to unveil for quite some time. We’ll be showing off some of what's to come at PAX East this weekend – if you’re attending, be sure to stop by our booth to get a sneak peek at the update as well as some goodies. If you’re not, don’t worry – we’ll be on the PAX East Twitch Stage Show on Saturday, so jump on Twitch at noon EST on Saturday 3/11 to see what will be coming very soon!

Public Beta Branch!

Hey astronauts!
We are pushing a public beta branch for the upcoming hotfix! Please feel free to jump in and leave any feedback and report any bugs by replying to this post or the forum post! We're doing this live Beta to test the graphics performance and texture streaming for any errors prior to sending out to a larger community, and to test the cheat reporting system.

See below for instructions on how to access the build, and have fun!

To access the testing branch, in your Steam Library simply right-click on the game, click on Properties, navigate to the Betas tab and under "enter beta access code unlock private betas" enter the code (without quotes): "ExperimentalZone"
Be sure to CLICK on check code (do not press enter) and then select "beta - public beta" from the dropdown menu! Download the update and launch!
Have fun and thanks for your patience on this one!

PS: If you do choose to check out the new Beta testing branch, it is recommended that you start a new character in the testing branch, rather than using any of your current characters.

Beta Release Changes:

  • Added malicious player reporting and timed multiplayer blacklisting to punish malicious/hacking players
  • Added texture streaming to greatly reduce texture memory usage
  • Added 3rd person shovel animation
  • Added message to show colony member avatar spawns

  • Updated Unity Engine to 5.5 which adds multi threaded graphics performance
  • Improved Ambient Occlusion and overall visual contrast and detail
  • Sound optimizations

  • Packable items durability is now saved
  • Fixed HUD typesetting
  • Infinite XP via barrel bug fixed

    Known Issues:
  • Texture streaming of structures or vehicles may look fuzzy of pink at a distance, but should appear when approaching these objects. This issue is temporary and will be addressed for the next update.
  • There may be performance issues in vehicles or when hovering. This will also be addressed by the next update.
NOTE: Characters and progress will NOT transfer to the live build!
Characters created in the beta branch WILL disappear.
Characters from before the beta branch will NOT.
The beta branch can essentially be thought of as a totally seperate game in terms of save data.

About This Game

“The oldest and strongest emotion of mankind is fear and the oldest and strongest kind of fear is fear of the unknown.” – H.P. Lovecraft

The year is 2046 and mankind’s discovery of near-lightspeed "fold engine" propulsion has empowered mankind's Osiris expeditionary missions to the Gliese 581 system. You are the second colonization team sent by the U.N.E. (United Nations of Earth) to study potential habitable planets when your spacecraft malfunctions braking from light speed, forcing an emergency landing on the planet’s surface.

Overcome the dangers of an environment with unpredictable weather conditions by building a central base, expanding the structure further with modular units to grow food, create research centers, manufacturing bays and more. To further advance technologies and thrive on the planet, traverse into a world filled equally with breathtaking landscapes and alien terrors that will freeze your blood. Osiris is a beautiful game that uniquely combines inventive crafting, curious exploration, and skillful combat. Explore an alien system and colonize worlds of incredible wonders and unforgiving dangers.


  • Multiplayer Colonization: Work together with online players to build a prospering colony and together defend against threatening alien species, survive environmental phenomenon including meteor showers, and attacks from other online player colonies.
  • Survive, Craft, Research and Thrive: Gather resources and materials to adapt to the alien system, build modular structures to grow food and create manufacturing bays, research new technologies to upgrade gear and build new vehicles and droids, and explore the environment to discover new resources and secrets to expand and thrive in this brave alien world.
  • Explore The Planet And Beyond: Learn what wonders and horrors lie on the alien planet and explore underground dungeons for unique potential discoveries. In time, build spacecraft to launch into space and travel to other planets in the solar system.
  • Prepare for a Fight: Choose first or third person controls as you hunt intelligent alien species with predatory instincts. Equip a variety of weapons to ensure you are prepared for any situation.
  • Light-Year Visual Difference: Experience the high graphic quality typically only found in AAA games. Osiris: New Dawn offers high attention to texture detail and High Dynamic Range lighting creating a frightening gorgeous world. An advanced IK (inverse kinematics) system powers over 200 amazing fluid player movements and a diverse range of terrifying alien creature animations.
