What the developers have to say:

Why Early Access?

“Interstellar Rift is an ambitious game that tries to push the boundaries of technology and gameplay 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 for roughly a year 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
  • Character customization
  • Interior industry automation
  • 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
  • Hostile aliens and drones
  • Procedurally generated space environment
  • Multiple star systems
  • Ship salvaging
  • Resource looting
  • Ship System damage
  • Missions
  • Generated stations and ships
  • Enhanced ship system management
  • 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!”

Learning new Lingidies- Interstellar Rift Development Update 078

The first official patch for 2017 is here!

So after a short while on the experimental branch we feel patch 0.1.37 is ready for prime time. Over the past few days we’ve already seen a very positive response, and great feedback, to the new translation tool. And we appreciate those of you who have already taken the time to translate part, or the whole game to your native languages. We will have some community reward tokens in the near future for those who help out the game in significant ways, including translations.You can only find these new translation files on the steam workshop for now, but we are working to make them available from an ingame menu as well.

For more information about translations, and how to upload one yourself, click here.

This patch will also make the new cargo missions available to everyone. Players will find these cargo missions only at GT trade stations. We will add them to the other factions as well at a later date. With this new mission we also introduced the ability to teleport cargo directly from your ship to the mission dropbox on the target station. Note that is currently only possible with the large cargo missions. Missions that require only a few crates will still require you to teleport over to the station and hand them in manually. Note we will be adding this functionally to the rest of the missions at a later date.

Skrill are now smarter as they try to dodge bullets, fly in more unpredictable patterns and attempt to ram your ship. Skrill hunters have also become more deadly as they now try to match speed with the ship they are attacking and make attack runs. Additionally we have also removed the behaviour where Skrill would not attack ships above a certain weight class. Skrill should now attack you regardless of what ship you are currently in. This should make going into Skrill infested star systems much more challenging and fun.

We’ve also spend some time on fixing up the options menu to be more in line with the industry standard. These enhancements will soon be making their way into an in game options menu as well, removing the need to go back to the main menu to make simple control tweaks.

As always, we’d appreciate any feedback you’re willing to provide as it will only help us make the game better. We hope you’ll enjoy this new update and we’ll see you star side!

Interstellar Rift has been in development since October 2012. Conceived after years of inspiration from games such as FTL and Garry's Mod with the Spacebuild plugin.
Interstellar Rift is built on our own game engine technology called Aluna, tailored to the exact needs of the project. Interstellar Rift began life as a project called AGOS. Split Polygon was founded in march 2013 with a team of five and development continued for just over a year before the project was renamed to Interstellar Rift.
