Early Access Game

Get instant access and start playing; get involved with this game as it develops.

Note: This Early Access game is not complete and may or may not change further. If you are not excited to play this game in its current state, then you should wait to see if the game progresses further in development. Learn more

What the developers have to say:

Why Early Access?

“We are ready to grow our community of players and testers by making PULSAR available on Steam. The community has helped us shape the game from an early Alpha build to a smoother and more playable experience. We want to expand our network of feedback to the Steam community and make PULSAR something special.”

Approximately how long will this game be in Early Access?

“PULSAR will remain in Early Access until it is ready for a full release on Steam. We estimate it will be in Early Access for 12 - 18 months. However, as we are serious about community feedback and have a very iterative-focused workflow, it is difficult to make any guarantees about the full release date. We need adequate time to implement user feedback and suggestions!”

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

“The Early Access launch version of the game has a small fraction of the planets, ships and sectors that are planned for full release. The full version will include 5 fleshed out factions with their own hubs, missions and ships, a large collection of planets and sectors to explore, and the Lost Colony itself. For more details on our current and planned features, see below.”

What is the current state of the Early Access version?

“The majority of core features have been implemented, but not a lot of content has been added to the game yet.

Some of the implemented features and systems have been listed below. They still need polish and balancing but are in-game.

Multiplayer networking, various video and game settings, status screen, teleport screen, ship claiming, various piloting and camera modes, reactor screen, auxiliary reactor screen, jump computer screen, coolant screen, fuel, distress signals, reactor core safety / meltdown, ship startup sequence, ship computer, virus screen, Atrium system / crew death, ship turrets, nuclear devices, gun-play, ship components, repair / trading / warp stations, NPC dialogue, missions and objectives, galaxy starmap, personal inventory, crew level and talent points, dynamic galaxy / galaxy chaos, persistent ship data, game saves, seamless warp travel, planets, ship programs, personal flight pack, ship-to-ship combat, sector commanders, creatures.

We strive to keep the game in a playable state, but it likely won’t be fully stable for a while. It would be wise to expect bugs, disconnects and the occasional crash as we continue to add features during this period.”

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

“The release price will be the same as the Early Access price (outside of any timed sales or promotions).”

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

“We have tried to maintain a strong focus on community interaction since the beginning of development. We post video updates to explain new features that have been added to the game, and we frequently communicate with players through the forum and emails. Although we are not able to respond to every piece of feedback, we try our best to read and take in as much of it as we can. The concept of PULSAR is rather open-ended, and our community has been a great help in providing us feedback to improve the game, as well as suggestions for content and features.

To get a better idea of how we work and the speed at which we make progress, check out our devlog videos on our YouTube channel here.”

Beta 19.4 - 19.6 Release Notes

Hey everyone!

Beta 19.4 is now out! This one should include a fix for those of you who have reported performance issues while playing in VR. Additionally it contains a few other fixes and additions.

We also tweaked the Auxiliary Reactor, making each option more powerful across the board, and added an Intruder Alert function. The Intruder Alert function should hopefully improve feedback about when the fight might be becoming more personal. For those of you who want to prevent enemies from boarding your ship (besides keeping your shield integrity up), you can pick up the new program “Quantum Defenses” which should ensure your quantum shields are online for a few crucial moments.

- Added more feedback for players when they try to customize their appearance or bot appearances, letting them know to visit a barber.
-Players can now upgrade maneuvering thrusters and inertia thrusters
-Main turrets can now be extracted
-Ship thrusters can now be extracted
-New Program: Quantum Defenses - Keeps your quantum shields online regardless on shield integrity or viruses (like gentlemens welcome) for 30 seconds. As long as a ship’s quantum shields are online, no enemies should be able to teleport.
-New NPC uniform - Human Male and Female Scientist
-New NPC uniform - Human Male and Female CU High Ranking Officer

-Extraction success rates have been slightly reduced
-Tweaked the WD HQ Station galaxy map
-Shield coprocessor charge rate has been increased

Aux Reactor Changes
-Auxiliary reactors values have been standardized based on the Intrepid
-Spotlights and Interior lights have been merged and are now named Lights
-Intruder Alarm has been added, it alerts the crew when enemies teleport onboard. It will flash a crew-wide announcement as well as add a notification to the chat box. If disabled it could provide 400 MW to the reactor.
The following information is based on an Intrepid-class ship from Beta 19.3.
-Aux Values - Atrium Healing increased from 400 to 600
-Aux Values - Oxygen Generation increased from 800 to 2000
-Aux Values - Air Filter increased from 400 to 1000

-Aux Values - Projectile Aim Assist increased from 200 to 400
-Aux Values - Cyberdefense increased from 800 to 2000
-Aux Values - Missile Lock On increased from 100 to 1200

-Fixed a lighting issue found on Outpost 448 that would occur on lower graphics settings
-Engineering fires should now be properly displaying on the status screen, and should properly damage the engine system.
-Fixed a few issues found at WD HQ
-Fixed a bug that would occasionally allow The Swarm to drop its hull component
-Fixed a networking issue related to the Captain plotting courses on the starmap
-Fixed a sound issue regarding ship damage
-Fixed an issue with an abandoned ship not appearing
-Fixed an issue that reduced performance in VR over several minutes
-Fixed an issue related to bots getting stuck while trying to repair a system on certain ships

Beta 19.5 Release Notes

Beta 19.5 is out! This is a quick update to address some of the changes we released earlier.

-The researchable Aux Power talent’s bonus has been reduced from 40% per rank to 10%

Aux Reactor Changes
-Aux Values - Oxygen Generation decreased from 2000 to 1000
-Aux Values - Air Filter decreased from 1000 to 400

-Corbin Taskerhall should now talk / sell face to face
-Bandit Drones should be less prone to attack one another
-Potentially fixed a sound effect bug related to probes

Beta 19.6 Release Notes

Beta 19.6 is out! This is just an update to fix a save issue that popped up. While working on Beta 20 we’ve been building a few new systems that involved the save-file format. Some of that code wasn’t ready to handle a pre-Beta 20 Release. Sorry for the inconvenience.

-Saves should now load correctly.

Thank you for your time!

Beta 19.3 Release Notes

Hey everyone!

Beta 19.3 is now out! Along with some fixes, it includes changes to ship hostility which make Colonial Union space safer and neutral space more dangerous. In addition we’ve changed some ship spawning properties to make reputation loss more predictable during the course of exploring the galaxy. It also adds a new Grey Huntsmen station and bounty missions.

We have spent a lot of time working on content that will likely be added in Beta 20, mainly the faction mission chain for the Colonial Union which will conclude with a bigger piece of content focused on exploring the Wasted Wing (the section of Outpost 448 that was recently severed from the main station for mysterious reasons).

We’ve also been experimenting with new networking solutions and how we might move the project over. It’s still early on that front but we feel it’s important to jump into that one prepared.

Here is a sneak peek of our work in progress:

-Bandit Drones can now be found across the galaxy. These ships will attack any and all ships they find. Attacking them incurs no reputation loss from any faction. Bandit drones are most common in neutral space, however there is a slight chance you can find them in Colonial Union space (blue sectors) and WD territory (orange sectors).
-In game manual has been updated and now includes sections on Ship Cloaking, Ship Sensor Dish, Item and Component Upgrade Stations, a several other tweaks.
-New Sector: Grey Huntsmen Bounty Agency
-9 NPCs added to Grey Huntsmen Bounty Agency
-5 NPCs added to Planet Crash 2 (planet with blue sand and crashed W.D. security drone)
-New Bounty Mission: WANTED: U.S.S. Xarius
-New Bounty Mission: WANTED: The Butcher
-New Bounty Mission: WANTED: Crumb Cleaners
-New Bounty Mission: WANTED: Unit 10, Div #44
-New Bounty Mission: WANTED: The Striker
-New Bounty Mission: WANTED: The Umbra
-New Bounty Mission: WANTED: The Drafters
-New Bounty Mission: WANTED: Biscuit Burners
-New Mission: Hunt Infected Carrier (given by Roka at Grey Huntsmen Bounty Agency)
-New Mission: Rid of Crawlers (given by Uleq on Planet Crash 2)
-Added a locked interior room to Cornelia Station for a bounty hunting mission

-Neutral space has been tweaked to be more dangerous, this should hopefully make it feel more chaotic and lawless.
-CU space has been tweaked to be less dangerous to ships of other factions. These sectors are meant to reflect civilization so CU ships and drones should only fire upon flagged ships.
-Crewed AOG ships now have the chance to be more directly hostile to other ships
-The Grim Cutlass sector commander is now considered flagged.
-Ship Processors should now get better when upgraded
-Updated Planet Crash 2 (planet with blue sand and crashed W.D. security drone)
-Original 5 Grey Huntsmen bounty missions have been updated with adjusted credit rewards
-It is now possible to join the Grey Huntsmen at the Grey Huntsmen Bounty Agency

-Made some performance optimizations to the starmap when loaded
-Fixed an issue that wouldn’t prompt a mission failure in some circumstances
-Fixed an incorrectly spawning sector that should only be available during a Colonial Union mission
-Fixed an issue that could cause corruption of item unlock progress
-Fixed a visual issue regarding the Item upgrade station on the Destroyer
-Fixed some pathing issues found at Cornelia Station
-Fixed a teleportation issue found at Cornelia Station
-Ancient Sentry no longer associated with the Polytechnic Federation
-Removed two mission-related planets from generating in the base galaxy
-Fixed an issue with long range comms in “Help CU Roland in Alliance Ambush” mission

Thank you for your time!

About This Game

Team up to operate an advanced starship and explore a randomized galaxy falling into chaos. Each player assumes a role aboard the ship: Captain, Pilot, Scientist, Weapons Specialist and Engineer. Coordination between your crewmembers will be essential in order to survive the perils that await you.

Control the various stations that run your ship. Reroute power between ship systems, scan alien planets for lifeforms, run powerful programs to change the tide of battle, or start up the warp drive to escape a conflict you cannot win. The strategies you use are up to you—or your Captain.

Embark on missions, investigate abandoned stations, and scavenge for components that could aid you in your voyage. Teleport down to the surfaces of alien planets, where you may face extreme environments and dangerous creatures. Trek across the galaxy, and discover what lies on its fringes.

PULSAR: Lost Colony is our attempt to create a fully cooperative space-faring experience, because it’s one of the games we've always wanted to play.

  • Gamepad support (work in progress)
  • Ship-To-Ship hailing (diplomacy, trade, intimidation)

Is there an in-game tutorial?

Not at this time. We are planning on integrating one in the future, however we want to make sure most of the ship systems are finalized before building it. If you want to learn about how to play and use the various ship systems, you can click here to view the manual!

Can I stream and/or monetize game footage?

Yes! This is our written permission to do so.

Simulation or Game?

We like using the term simulation because it helps convey the fact that each starship is a large collection of systems and mechanics working together and reacting to its environment. However, this is a game first and foremost. Because of that, we aren't afraid to go outside the realms of reality if it makes the experience more enjoyable. This is not a 100% realistic simulation, it's a game with simulated elements.

Player versus player modes?

PULSAR was designed from the ground up to be cooperative in nature. None of the mechanics are prepared to handle the specific challenges of PvP combat. We believe that this focus on pure cooperation will enable us to create an experience that is unique and feasible by our small team.


We are focusing on a multiplayer experience at this time. We do offer AI crew bots that can take over unfilled roles, but they are very much a work in progress. The game is very teamwork heavy so the recommended experience is with multiple people. If you looking for a more complete singleplayer experience, you may want to consider waiting until the AI is fully developed.

Where can I get more information?

For more information, check out these links below:






The game is currently under development. New systems and mechanics are still being added and tweaked, and there is not a large amount of in-game content to see yet.

If you prefer to play more complete games and have no desire to be part of the testing / feedback process of a game in development, we highly recommend waiting until the game is more complete before considering a purchase.
