Build tiny voxel worlds in virtual reality! Microcosm is the game I've wanted to play in VR ever since I saw the Oculus Rift Kickstarter way back in 2012. I picked up a Vive last year, but no one seemed to be making the voxel game I wanted. Finally, I said enough was enough, and just decided to build it myself.

What the developers have to say:

Why Early Access?

“Early Access is going to be a great way to make sure Microcosm runs well on a variety of systems. Since I'm just one person with one test machine (currently), this is one of the more difficult parts of VR dev.

I'm also very excited to use the Early Access period to learn how other folks interact with and use the game, and make changes, additions, or removals accordingly.”

Approximately how long will this game be in Early Access?

“At most, I'd like the Early Access period to be a few months long. Once I'm comfortable enough with Microcosm's stability, performance, and feature set to move it out of Early Access, I'd love to keep adding updates as long as there's still both player interest and good things to add.”

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

“Beyond stability and performance improvements, here are some of the features that are currently planned:

  • More voxel colors
  • More voxel types (Currently looking into a "chiseled" variant)
  • Day/night cycle control (Speed and play/pause)
  • Steam achievements

Here are some features that may be added, but are currently still under consideration:

  • More export and sharing options. A way to quickly publish and share Microcosm worlds online is something I'm very much interested in building.
  • Multiplayer support.
  • Other VR platform support? Probably Oculus Rift + Touch first, but I'd love to eventually release Microcosm for other VR platforms, too. This is dependent on customer interest, as I currently only have a Vive.

Everything in these lists is subject to change, depending on what I learn from more internal playtesting, customer feedback, and other factors.”

What is the current state of the Early Access version?

“Microcosm is usable and fun in its current state, according to testers. Personally, I tend to get sucked in when I'm trying to test something, and often find myself just drawing for a while instead.”

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

“Nope! This is the planned final price.”

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

“As mentioned above, I'm very much looking to tuning performance and stability. A big part of this will be relying on feedback from users. Of course, it will also be great to get gameplay feedback as well!”

Bugfix update: 0.1.6

I just released Microcosm 0.1.6. The only change in this update is a fix for a bug that could cause lights to be saved and loaded in the wrong position.

Microcosm 0.1.5 Release Notes

Hey folks! It’s been longer than I would have liked since my last update. Things are very hectic in my life right now. My day job is on the verge of a big launch, and I’m also preparing for an upcoming house move. I’m still dedicated to improving Microcosm and adding lots of new features, it just isn’t moving quite as quickly as I’d originally hoped.

That being said, I’m very happy to release 0.1.5. The biggest addition is Oculus support! I wasn’t originally planning to add Oculus support so soon, but the folks at Facebook ended up sending me a Rift + Touch development kit, and I couldn’t resist adding it right away. A big shoutout to VRTK and the folks in the VRTK Slack, which helped make adding Rift + Touch support incredibly simple.

The other main change in this release is a slightly increased base voxel size. Microcosm voxels are now 0.024 cubic meters, instead of 0.018. Any game saved in 0.1.4 will be automatically migrated to the new voxel size when opened in 0.1.5 or later. This change makes drawing a bit more forgiving, especially under suboptimal tracking conditions.

Steam Cloud support has also been added, so your save files will automatically be backed up and synced between your computers. Beyond that, this release includes lots of behind the scenes tweaks and changes. These changes don’t affect gameplay in most cases (other than things like some additional haptic feedback), but will make it easier for me to keep improving Microcosm going forward.

Until next time,

About This Game

Build tiny voxel worlds in virtual reality!

Microcosm is the game I've wanted to play in VR ever since I saw the Oculus Rift Kickstarter way back in 2012. I picked up a Vive last year, but no one seemed to be making the voxel game I wanted. Finally, I said enough was enough, and just decided to build it myself.

I hope you enjoy playing Microcosm as much as I enjoy making it. If you had any issues, or if there's something you think I could improve, I'd love it if you let me know. Please feel free to get in touch with me at any time. If you've found a bug, screenshots and system information are very much appreciated, to help me reproduce and fix it.


  • Microcosm worlds are made of 512×256×512 voxels. Each one is 0.018 meters (~0.7 inches) cubed. That's over 9 meters across and 4.5 meters tall of real-world space (~30 feet by ~15 feet). You can build some pretty huge stuff. 🚀
  • Create your own world of solid, transparent, and glowing voxels. 🖼
  • Switch the desktop camera mode! Use the default eye-cam, or place a fixed camera in the world. Great for time-lapses, video recording, and hiding your work. 📹
  • Save your creations as .cosm files, and share them with other people! 🌏
  • Intuitive voxel selection and editing. Easily place, delete, and paint existing voxels. 🎨
  • More fun and interesting things coming soon! Check out the roadmap announcement post to learn more. 🎉
    • Pause, speed up, and slow down the day/night cycle.
    • A lovely, custom soundtrack composed by Mr. Kevin Jachetta!
    • More ways to share your Microcosm worlds!
    • (maybe infinite terrain, too)

Microcosm currently supports the HTC Vive and Oculus Rift + Touch.
