Rings of Saturn

Nominate us for Steam Awards!

Labor of Love award is for games that are out for a while, but devs still continue to nurture and support their creation.

ΔV: Rings of Saturn entered Early Access over two years ago. Since then we squashed 1859 bugs, added 714 new features (many of which were suggested by our players on our discord.gg/dv), released 2164 bleeding edge and 281 new stable versions. We came a long way and we still aim to improve at a steady pace.

Nominate us!

0.427.2 - Impulse Shielding


  • New auto-exposure and tonemap settings make the screen not go so dark when you use bright light sources.
  • You could get multiple rewards if you managed to re-dock to Big Bad Wolf after releasing prisoners.
  • Tab navigation shortcuts were backwards.
  • Stray bullets that you had autopilot lock on will lose that lock when you catch them in your cargo hold.
  • Items that are held in salvage manipulators and cradles cannot be targeted by guiding drones anymore.
  • Autopilot rotational adaptation for ER42 and MA-337 autopilots were confused by powerful pulsed thrusters, making the rotational manoeuvres erratic.
  • Individual disposition changes for patrols propagate, so you won't end up with one Vilcy leaving you alone while other shadows you or one pirate harassing you when you made a truce with the other one.
  • Phage-class stations and habitats won't try to rotate to face you anymore.
  • Some pilots - civilians, Vilcy and pirates alike - can fly on manual, not relying solely on autopilots. Microwave emitters will still disrupt their flight but will not stun everyone unconditionally.
  • The dialogue option that results in you hanging up now has a distinct hang-up indicator.
  • Fixed Edge Runner ship thruster allocations, so it's nimble again.
  • Drones and claim beacons won't try to turn to face you.
  • AI will not be afraid of itself - and thus, your point defence will never shoot your beacons nor drones.
  • Astrogating with a lifepod in a cradle won't cause your ship to spin uncontrollably.
  • Increasing physics simulation FPS caused your excavator to deal less damage to rocks.
  • You can't send over your crew to a ship that is currently salvaged by the search & rescue team.
  • CERF search and rescue craft will not rotate to fly backwards during fast transits, as its symmetrical and backflip serves no purpose.
  • Derelict ships your crew managed to boot up won't follow you through astrogation jumps if you choose to astrogate before they depart.
  • Catching ship with AR1500 manipulator when you have an autopilot lock on its reactor or other equipment will release that lock.
  • Adjusted physics collision settings to prevent cargo from phasing through ship hulls.
  • Derelict ships are now more damaged and should be a bit more challenging to catch.
  • You can now ask Vilcy patrols for drop point coordinates even when you already have a bounty-hunting licence.
  • The "Reset to default" button for microwave resonance tuning will correctly reset the slider to 50%.
  • Adjusted the cargo hold of Elon Interstellar Model E to prevent ore from causing damage from inside the cargo hold.
  • You cannot abuse claim beacons to generate multiple events astrogating between the two. They will now attract just one event per dive.

0.424.2 - Rearmed


  • Fusion reactor rebalance - the fusion powerplants of ships will not shut down when your ship is damaged by electromagnetic pulses or microwaves.
  • New achievements.
  • Added photosensitivity warning screen.
  • Fixed scale of electromagnetic sparks on Elon Interstellar Model E.
  • Display of the EIME HUD is now darker, making it easier to see the background.
  • Auxiliary Power Systems are now counted towards power warning in the Upgrade menu.
  • Foreground rocks were missing in point defence upgrade simulation.
  • Setting background FPS to 0 will not block preview and promotional videos in the Dealer menu.
  • The AR1500 Manipulator will not throw away light objects you approach slowly.
  • Multiple adjustments to manipulator and docking arm code, making them behave more like real machines.

0.422.9 - Curved Rock


  • Replaces libraries bundled with M1 build with correct ones.

0.422.3 - Depths of Uranus

The Synchrotron Controversy


Omaewamou-Shinderu’s most recent entry in the realm of weapons manufacture has earned imports from Uranus and especially its moon Miranda embargoes or bans in most systems on the grounds of safety and environmental concerns. Named after the spear that Odin would carry into battle during Ragnarok, this repurposed small proton collider has been stripped of most safety and measurement equipment. The charge it carries is enormous and takes time to dissipate in the rings, creating a very hazardous environment to mine in. Enceladus Prime has not yet made any regulatory rulings on this device.



New photosensors for reconnaissance drones


In a collaboration between Runasimi and Obonto Micro Engineering, new standards have been agreed upon regarding recon drone photosensors. Anticipating a drop in costs associated with standardized supply, the new photosensors promise better image clarity, with a higher dynamic range and onboard postprocessing.



Superconductor Improvements


Exiting a phase of testing and feedback, safety regulations surrounding this relatively new technology have been lifted. With an established track record of safety, SMES systems are now approved to operate much closer to their theoretical full potential, making them much more useful and reliable in providing a large power reserve for periods of peak usage.



Maintenance Records



  • New SPC Gungnir Proton Cannon.
  • Game engine upgraded to Godot 3.4, featuring: better stability, performance and native support for M1 processors.

  • Hacking enemy ships will now have more random outcomes.
  • Fixed race condition that could make the game crash when ships were exiting detailed simulation range.
  • Updated translations.

0.416.2 - Memory Leak

New hardware simulation provider


Electro Ride Systems won their bid for the deployment of spaceflight simulation software to Enceladian Shipyards, replacing the well-known Nakamura Dynamics spaceflight simulators. Spokespeople for ERS assured us that their 3.0 simulation software is as accurate as their competitor’s, and features a comparative simulation mode. Nakamura has challenged the validity of the bid, citing insufficient resolution to meet the contract parameters.


Subcontractor records leaked


An anonymous hacker leaked all Enceladus Corp subcontractor records, including estimated excavation yields, financial status and other private documents. Local ATLAS operatives launched a full-scale investigation hinting at possible AI connection. Enceladus representatives refused to comment.


Updated salvage policy


An investigation into the reckless endangerment of crew health and safety found a surprising resolution, as an Enceladus Corp Board of Inquiry exonerated a captain who permitted a crewman to perform EVA repairs on a derelict to prepare it for intralunar transit. While experts from Enceladus shipyard regard such operations as near-suicidal, this new precedent opens up new opportunities - and new risks - for unlicensed salvage operations.

  • New External Impact Absorber upgrade.
  • Expanded the bounty hunting dialogues.
  • Smoothed the camera zoom and made it respond faster to zoom controls.
  • Changed the algorithm for ore collision detection to prevent ore from being stuck in the reactor after a high-velocity impact.

  • When tuning weapon systems, the simulation window will now present boresights.
  • Improved integration with Steam services and overlay.
  • Several stability improvements.

0.403.11 - Forbidden Tales

New wergild rates


With the alarming rise of crime rates, Enceladus Corp sanctioned the next increase of wergild rates, ranging from 10,000E$ for property damage up to 50,000E$ for aggravated assault. Unlike bounty, wergilds are only to be collected by a licenced bounty hunter. Individuals seeking a hunter licence should contact your local Vilcy operative.



Anarchy Sightings


The terrorist organization known as Ganymedean Anarchy claimed responsibility for multiple attacks and extortions in the rings. With suspicions of the group being supported by citizens of the Enceladus Prime stations, station authorities launched a full-scale investigation into the matter. As to this day location of the base of operations of the nefarious group remains undiscovered.



Ganymedian Prejudice


With increased pirate attacks, many Ganymedean citizens who sought refugee on Enceladus after the Titan crisis are facing waves of prejudice and hostility. While stations authorities issued a statement condemning the acts of violence, the local Vilcy spokesman offered no comments under the pretence of an ongoing investigation into the matter.
