About this game
Strap into a sleek shuttle, drop through a planet’s atmosphere, and step onto its surface. Then lift off, break orbit, and aim for another pinprick of light across the system. In Holospace, there are no loading screens between worlds—just one continuous procedural universe stretching as far as you are willing to fly.
One seamless journey, surface to space
Pilot your ship from the ground, through the atmosphere, into open space, and onward to the next planet—all in real time, without cutting to a loading screen. Land, leave your ship behind, and explore on foot as you run, sprint, jump, and jetpack across voxel terrain beneath changing skies, day-and-night cycles, and rolling weather.
A vast procedural universe
Every planet is shaped by its own seed, influencing its palette, gravity, terrain, biomes, oceans, weather, resources, and ecosystems. No two worlds are exactly alike.
Each planet draws from a growing library of distinct creature species, procedurally adapting their size, coloration, surface patterns, behavior, rarity, and habitat to create local fauna unique to that world.
Your home world is always waiting. Everything beyond it is yours to chart.
Mine, craft, and build
Carve into the terrain with a plasma cutter, gather increasingly valuable materials, and craft equipment at deployable stations using a shaped recipe grid. Place blocks, construct structures, and reshape the places you discover—your changes to a world persist.
Gear up
Wield a growing arsenal of plasma rifles, SMGs, rifles, scatter guns, and glowing plasma blades. Customize your exosuit with craftable styles and upgrades, and summon a glowing Echo orb to illuminate dark environments and help you traverse the unknown and find ore.
Survive the firefights
Worlds can erupt into Strikes, where dropships descend and waves of hostile creatures and armed Voiders close in. Face rushers, ranged attackers, and heavily armed enemies capable of taking cover and flanking your position.
Hold your ground—or make a run for your ship.
Beware the dark
Deep space hides wandering black holes. Real-time gravitational lensing bends the surrounding starfield around glowing accretion disks, while powerful gravity wells reach far into space.
Stray too close and the pull can become inescapable. Spiral inward and be stretched into a fine cosmic noodle—or be hurled across the galaxy through a wormhole.
Fly together
Host or join a game over LAN and explore the universe with friends.
Make it your own
Maintain multiple saved “universes,” each with its own seed, worlds, discoveries, and places to call home.

Environmental Hazards
This dev log is about showcasing a newly added environmental hazard: meteor storms.Meteor storms can occur randomly at any time while exploring the world, without warning. When one triggers, the environment becomes increasingly dangerous as debris begins raining down across the terrain.If you find yourself caught in a meteor storm, stay alert and keep moving—open ground becomes especially risky, and impacts can happen both near and far from the initial strike zone. These events are designed to disrupt exploration and force quick decision-making under pressure, so don’t assume any area is truly safe.Watch the skies… and be ready to react.Read full article on Community Announcements (Antimmatr)AnnouncementsOfficial
Addition of Abilities
In this dev log, I’m showcasing the special abilities system—specifically the Bubble Shield. As the name suggests, this ability generates a protective shield around the player for a limited duration after being deployed by throwing it to the ground. Since it’s a special ability, it has a cooldown period before it can be used again. More special abilities will be introduced throughout gameplay, each offering unique tactical or explorative advantages.Read full article on Community Announcements (Antimmatr)AnnouncementsOfficial
Teleport Modules
Two new craftable items have been added to the game. One is a Transit Module which allows you to link two of them together anywhere on the same planet and teleport between their locations. The other is a Warp Module which behaves similarly but allows you to only teleport from one planet to another wherever you set them down. It initializes a dematerializing animation on the players character and then a materializing animation upon arrival at the destination module.Read full article on Community Announcements (Antimmatr)Patch NotesOfficial
Jetpack Improvements
Jetpacks have been updated to provide a much more versatile flight experience.Previously, jetpacks primarily allowed players to gain altitude while offering only limited forward movement. With this update, they now provide significantly stronger forward thrust, making it much easier to fly across the terrain, traverse larger distances, and explore the world more efficiently.This change makes jetpacks feel more responsive and useful for both exploration and general movement, while still preserving their role as a mobility tool rather than a replacement for other forms of transportation.Read full article on Community Announcements (Antimmatr)AnnouncementsOfficial
Caves
Caves are dark. Only a small area around you is lit up as you navigate through them with some areas also lit up from crystals. Eyes keep watch on you as you move through them. What else will you find in them?Read full article on Community Announcements (Antimmatr)
