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 17.2 Release Notes

Hey everyone!

Beta 17.2 is out! It contains various changes and fixes.

Resetting your default keybindings will allow players to further customize their piloting settings. New optional bindings allow pilots to access maneuvering thrusters without toggling maneuvering mode. This allows pilots to potentially access both maneuvering thrusters and rotational thrusters while piloting in manual mode, which was not possible before.

One of the less noticeable changes we’ve made is move a few random elements to be more deterministic. This means that while they are still random, they act predictably during reloads (reloading a save and warping to the same sector will yield the same ship with the same components installed, it will be in the same location and will drop the same components / scrap)

We’ve also added a way for crews to make an enemy ship neutral before claiming it, allowing a bit more flexibility than before. More information about that below.

-Added a new temperature unit you can choose to display temperature with: Kelvin
-New behavior for SciBots: will occasionally fire probes and rotate sensor dish looking for things in a sector
-A new step is added in the claim ship process - after capturing enough screens and heading to a status screen, you must now remove the enemies claim before you can place your own. We think this will be a valuable additional step because it now allows you to prevent enemy crews from respawning as well as allow you to extract components from the ship and perhaps steal cargo if it has any, all while keeping your original ship claimed and preventing you from getting a “flagged” status.
-New Ship-wide notification: Removed enemy ship claim
-New Ship-wide notification: Ship claimed
-New sub-priority for Scientist’s Man Station (found under behavior tweaks) : Search for ships - the scibot will continually search around using the sensor dish, and will fire probes when this sub-priority is the highest one in main priority

-Enemy ship components are now more deterministic
-Enemy ship modifiers are now more deterministic
-Enemy ship component chaos boosts are now more deterministic
-Scrap is more deterministic
-Ship starting locations should now be more deterministic

-Fixes a few reported issues with the sensor dish
-Fixed an issue that may damage players and bots when switching from an interior to an exterior area or any time a pawn is instantly moved without using a teleporter
-Fixed a sound issue that caused players to hear and see probes fired on planets
-We’ve done some work making sure graveyard assets are despawned properly, let us know if any of you continue to have issues
-Fixed an issue that might prevent players or bots from properly exiting the sensor dish when they lose their claim or when they are removed from the game
-Fixed issue that could cause AI priority data to not be reset when the player quickly started a game after selecting upgrade in the AI version upgrade menu

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.

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.
