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!”

Interstellar Rift Player Designed Ships Contest 001

We are proud to announce the first in a series of ship building challenges that will give you the chance to have your ship design featured as one of the faction ships in the game! Your name will also be immortalized in the credits of the game!

Over the next several weeks and months we will hold contests each of which will be dedicated to a ship and faction. Each ship will have a specific role that it needs to fulfill and that comes with a set of requirements that need to be met for your submission to qualify.

The requirements for each ship will range from weight limits to what kind of tier of devices can be installed and its general purpose. We will be judging the ships based on their user friendliness, design aesthetic and and how well they fit into the required role.

Now without further delay, the first ship design challenge will be to create a new HydroPEX ship.

Ship description:

A fairly large HydroPEX tanker ship with plenty of cargo pads and a public service area, the ship will be used in a similar way as the GT Travelling Trade Emporium.
This ship will periodically visit systems to sell different types of fuel, based on the tier of the system.


Ship requirements:
  • 1 HydroPEX Service Depot, and 1 Drone Control Device in a publicly accessible room.
  • Plenty of cargo space in rooms behind locked doors (10 or more full tile cargo pads).
  • 1 large armor generator.
  • 1 Quantum Generator (infinite power gen).
  • 1 Quantum Life Support Systems (infinite oxygen gen).
  • Exterior needs to (at least partially) use the HydroPEX Red, White, Green color scheme.
  • Ship mass can not be more than 250k.
  • Bridge and cockpit need to be behind a locked door.
Things not to do:
Other stores or admin models should not be on this ship.

Contest Rules:

As with every contest there are rules and regulations that everyone must adhere to so here are ours.
  • All submissions must be original, ships resembling established designs outside of Interstellar Rift will be disqualified
  • The contest will run from the 19th of September to the 3rd of October any submission made after the end date will be disqualified
  • All Submissions may NOT contain and of the following, graphic or sexually oriented imagery. any depictions of or related to drug use, political views outside of those present inside of Interstellar Rift.
  • Split Polygon reserves the right to alter any winning submission before implementing it into the game.
  • The contest is open to anyone.

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.
