What the developers have to say:

Why Early Access?

“Interstellar Rift is an ambitious indie game that uses a custom build game engine to push for a new kind of space sim. We want players to have the freedom to create and maintain any ship they can imagine. While keeping the world filled with missions and events, in an attempt to create a world that players want to explore and inhabit. Naturally, this comes with many challenges from both a technical as well as a design perspective. In order to tackle these challenges as effective as possible we want players to get in and play as early as possible so we can improve the game in a way that our players will enjoy.

Initially we released the game for free to the community. During this period we have actively listened to feedback and ideas which in turn has helped us to make Interstellar Rift more fun, intuitive and overall a better game. We at Split Polygon aim to continue to use the community’s amazing feedback and support to create the space sim we always wanted to play.”

Approximately how long will this game be in Early Access?

“We estimate that Interstellar Rift will remain in early access until roughly the end of 2018, before we feel the game is ready to be labeled as done. Although due to the nature of the game we could continue development indefinitely beyond the core set of features we have planned. And depending on the success of the game we most likely will do exactly that.”

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

“The early access version is still missing some of the game-play features. However the core has been implemented. Over the next few months we are planning to expand this by adding some of the following features (in no particular order).

  • Space NPCs
  • Ship Interior NPCs
  • More graphics options
  • Space environmental effects
  • Food mechanics
  • Hangars
  • Advanced dedicated server options

In addition to tons of bug fixes, performance optimizations and feature iterations we will be taking feedback from you, the players, every step of the way to ensure that Interstellar Rift lives up to both our and your expectations.”

What is the current state of the Early Access version?

“The early access version has the following core features in place:

  • Space Combat
  • Interior industry automation
  • Character customization
  • Hostile aliens and drones
  • Procedurally generated space environment
  • Multiple star systems
  • Ship salvaging
  • Resource looting
  • Ship System damage
  • Missions
  • Generated stations and ships
  • Solar System events
  • Item crafting (weapons, tools, ship upgrades)
  • Ship editor
  • Multiplayer
  • Player hosted servers
  • Ship flight
  • Ship Interior Combat
  • Resource mining and refining
  • Explorable universe
  • Simulated ships with life support, fuel consumption and power systems
  • GRIP multi tool for interacting with systems
  • In world cargo storage

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

“Yes, during the early access period the game will be available for a lower price to compensate for the incomplete state of the game.”

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

“Initially we have had a pre-alpha version of Interstellar Rift freely available. During this time we have listened to player feedback and it has helped improve the game tremendously. We intend to continue this process through our forums, Twitter, Facebook and now the Steam forums. The game will be updated every two weeks with new features, bugfixes and more. During this time you can ask us anything, anytime. Community feedback has always been and will continue to be extremely important for us. In short, feel free to drop us a message if you have a question!”

Patch notes for Interstellar Rift BETA


- added a new Teleportation Automation Cartridge
  • Resource cost: 10 gold, 10 silver, 10 silicon
  • Can be made with a 3D Printer
  • Can be inserted into a Cargo Teleporter
  • Will teleport Cargo every 6 seconds
  • Can teleport to cargo pads, cargo containers, vaults(the vault of the person who activated it), hydrogen tanks, dronebays and dropboxes
  • Lasts for twelve hours

- added speed tracking mode (P), which can be used while in the cockpit of a ship to set the speed to the speed of a target, and match their speed over time

- added speed matching mode (I), which can be used while in the cockpit of a ship to set the speed to the speed of a target for one time

- Refinery can now be stopped

- Extractor can now be stopped

- Extractor can now select a priority resource, by clicking on a resource while it's mining

- added new command to exit a game/server
  • command ingame: /exittimer, /quittimer
  • command in server console: exittimer, quittimer
  • parameters: <duration in seconds> <optional popup message text>
  • example: /quittimer 120 "Server shutting down for maintenance."

- added a new server configuration option ActiveDronesInTileRemovalThreshold (defaults to 20). This controls the amount of active drones (of the same type) have to be in the same tile for them to be considered for despawning. Low values of this setting will result in performance degradation due to constant spawning and despawning of trading and mining drones.


- added Station Shield error messages to the localization file

- game now shows a message to notify the user to install the VC++ 2012 Redistributables when a DllNotFoundException is encountered

- tool drop code for the Cloaking Device and the Station Shield was rewritten to prevent loss of tools on server lag


- fixed drift to point position of disposed beacon and defense drones

- refineries no longer accept mission resources

- fixed a crash for refineries with mission resource in their buffer

- fixed an exception thrown by the logger when loading a system

- force update inactive systems with an available ghost client for one frame when requesting save data from them

- fixed some issues where the loading screen would not show properly

- fixed some issues with unloading servers

- attempted to fix a crash in the repair gun beam

- keep track of what systems players are in for better ghost client handling

- fixed hired S3 combat drone targeting

- fixed drone despawn timer

- fixed Station Shield and Cloaking Device respectively not accepting Focusing Crystals and Heatsinks when they should

- disable toggling of points of interest markers in the shipflight UI because it doesn't work correctly and leads to confusion as to where the markers are

- unified spelling of Heatsink

- removed extraneous brackets around the Focusing Crystal duration in the Station Shield

- fixed crash when an FPS bullet hit something that did not have a visual

- fixed searching in drone bay resource popup

- fixed player stores continuing to sell to / buy from drones when they were unpowered or turned off


- servers need to be updated and restarted

Follow Me! - Interstellar Rift Development Update 150

In this weeks’ update we have addressed a couple of smaller issues, and implemented some much requested quality of life features. Among other things, there’s now an automation upgrade for the cargo teleporter, and a speed tracking and speed matching mode for ship flight.

Automation for the cargo teleporter has long been on our to-do list but it’s finally here. You can now purchase a teleportation upgrade cartridge at “selected vendors” (LogiCorp, GT Travelling Trade Emporiums, etc.) or print it yourself with a 3D printer.
Once inserted in a cargo teleporter the upgrade cartridge unlocks a new menu in the top right of the terminal, which can be used to set a target location. Once you set the cartridge to “active”, the cargo teleporter will automatically start teleporting resource crates every 6 seconds.

In the cockpit you will find two new buttons on your dashboard. These let you either track the speed of a targeted ship, (up to your ship’s max speed of course), or match the speed of a targeted ship once. With speed tracking mode, your ship will automatically adjust it’s speed to keep it the same as its target. Your ship does not turn automatically though, so this won’t work in battle to keep locked onto an enemy.

The extractor has received two new functionalities, you can now stop mining at any given moment, and you can select which resource should be mined. Which means that you can select a rare resource from an iron asteroid for example, and the extractor will switch to mining that first. Stopping the mining operation destroys any remaining resources in the asteroid.

The refinery has also received the stop functionality, but it will not destroy any resources, instead it will finish its current batch before cancelling the processing command.

Besides functionality tweaks we’re also always working on optimizing the game and fixing bugs. This time we’ve fixed some long standing annoying bugs with the trade terminals and how they interact with drones, fixed the drift to point code for the beacons and defense drones, and resolved a couple of issues with mission resources and refineries, among other things.

Thank you all for playing and see you star side!

About This Game

Interstellar Rift is an open world Starship Simulator with an emphasis on ship construction and multi-player interaction. Players can explore and conquer the galaxy with their own custom designed and constructed starship. Space is vast, but you wont have to face it alone, other players will be able to join your crew, and help out, or build their own rival fleet and fight you across the galaxy.

Prepare to make these custom build space ships your home when exploring the galaxy! Use the ship editor to design a ship to your liking, from small exploratory vessels to large cargo haulers, or even enormous battleships. With the editor you build your ship deck by deck, inside and outside. If you'd rather get going immediately you can always browse the workshop for ships that other players made, or you can upload your own blueprints.

The galaxy can be a dangerous place, even when playing solo. Strange rifts have opened up, unleashing a hostile race of alien creatures called the Skrill. If left unchecked, they will take over solar systems wreaking havoc on your enterprising. You can fight them alone, or call in the help of your friends, and man a ship together. But not all pilots will fight for a good cause, pirates and opposing fleets can come after you and your cargo at any time. Fight them ship versus ship, or hack your way aboard their vessels and bring the fight to them, in close quarters shootouts.

The economy of Interstellar Rift runs on the resources that can be gathered out in the galaxy. Vast asteroid belts circle planets and solar systems, filled with precious ores and minerals. Start up your resource extractors, or send out a wave of mining drones to do the hard labour for you. Visit the stores of LogiCorp and Galactic Trade, or drive a hard bargain with stranded pilots as you delive them fuel. Automate production lines with the ACTR (automated cargo transfer relay), and set up your own store to trade with other players, or any trade drones that might be nearby.

After choosing a faction to ally with, the galaxy is open for you to explore. Use rift generators to open up spatial rifts that transport you to new systems, exploring a system will help you map out the galaxy, and pinpoint the location of systems with special resources you might need. Construct new trade posts for the companies and factions that want to expand their influence, and help them set up secure stations and sectors. Take on missions for U-nits, or find good deals across multiple systems to make a profit from.
