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 10.4 Release Notes

Hello explorers!

Beta 10.4 is out now!

This one is a bit more content focused than usual for these types of updates. We wanted to add a contraband system to the game for a while now, and we took this update as an opportunity to do just that! We think it helps make being a Gentleman a little more dangerous.

We added a handful of new, colorful components that in one way or another are illegal to have in your possession.

But what is contraband without the risk of getting caught? Colonial Union inspection stations are now in the galaxy. When in Colonial Union space, they select ships at random for a full ship inspection. If you don’t have a spot to hide your illegal cargo, you’ll be at great risk of getting caught when the station investigates your ship. If you do have a spot to hide all of your illegal goods, make sure to stash away your cargo, and you may be able to sneak it out safely.

Running from an inspection station request will result in your ship being flagged. Your ship will also be flagged if they spot cargo during the investigation, and they will also attempt to destroy your ship, so be careful!

Inspection stations like to be thorough. A CU investigator bot will board your ship and begin to examine your ship's interior. It’ll inspect ship systems, ship cargo, and player lockers. This means if you have some kind of contraband item in your locker, you’d better remember to get rid of it!

-New system for contraband
-Hidden cargo slots on AOG ships should now work appropriately
-New Cargo - Contraband items; most shopkeepers won’t buy them, and you could get in trouble if you’re caught with them.
-New Sector: Colonial Union Inspection Station
-New Station: Secret Cryogenics Facility (quest related)
-New Planet - Poison Mist (quest related)
-New Planet - Borthix Mining Operation (quest related)
-Automated ship investigator - New object that will fly around and investigate your ship for contraband items. There is a small chance it might find your hidden stash if you have one.
-4 new AOG smuggling missions

-The Estate’s reactor room is no longer as dangerous as it was in 10.3

-Fixed a few minor geometry bugs on one of the toxic planets
-Fixed an error that would occur during bribes or Long Range Warp Station purchases that would sometimes give your crew a negative credit balance
-Saving/loading an AI crew should now work a bit better and now stores bot names / genders

We know quite a lot of you are requesting more content, so that’s what we’re going to be focusing on in the coming updates. Thanks for the reports!

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.

Current Features

  • Online drop-in / drop-out multiplayer
  • Command and control an advanced starship
  • Five unique classes; everyone plays a role on the ship
  • Fast-paced and tactical ship-to-ship space combat
  • Teleport to other ships, planets or stations to join the away team
  • Loot planets and stations for valuable items
  • Board enemy ships to capture them or destroy systems
  • AI crew bots (work in progress)
  • Research and Sample Collection
  • Gamepad support (work in progress)
  • Ship-To-Ship hailing (diplomacy, trade, intimidation)

Planned Features

  • The Academy (In game tutorial)
  • Meta-multiplayer (daily leaderboards, etc)
  • AI crew bot improvements (with advanced specialties for classes and enemies)
  • Better Captain tools: contextual order system, AI priorities
  • SteamOS support
  • Oculus Rift support
  • Offline LAN support
  • A healthy amount of polish and love to the systems we already have
  • Optimization improvements
  • Challenge modes
  • More languages
  • A large amount of content to explore and interact with


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.

This needs to drop price and offer a friends pack sale or something. I really want to get this for friends to enjoy but will not pay 30$ cdn to do so, just for a single copy of a early access game.

8/10 price needs to drop.

If I had the money, I'd give the devs a couple million dollars to turn this into a AAA multiplayer coop game. The concept is spot on.

- Real Star Trek like experience in multiplayer. It's amazing. It really is. If you don't believe it watch a Let's Play on youtube.
- Incredible immersion. You are on your post. In a battle you have your job to do. You need to trust your captain to maintain a grip on the overall situation, because you sure can't, as you have to keep the reactor from exploding etc.
- Runs smoothly at 2K on my gaming rig.

  • The nice way to say it is: It needs polish. Looks like a game of the very early 2000s.
  • Even though it looks like it is from the past, it runs terribly on integrated graphics. Couldn't get any playable performance on my Broadwell laptop with Intel GPU even with every setting at the minimum and resolution at 1024x768.
  • Little actual content in the way of missions or anything else at this point, but the devs are on it.
  • It's less fun if you play with AI bots instead of a real crew of people.

Verdict: If you have a couple of friends and you love Star Trek-like SciFi, go for it.

Suggestions for the devs:
  • The shop could directly compare what's available to what's installed in your ship. Alternatively, give the engineer a nice one page overview of the ship components.
  • A "stop all thrusters" button would be nice for the pilot, so would be piloting via gamepad.
  • I would welcome more realistic physics for piloting: The ship doesn't decelerate on its own, keeps spinning unless you stop it with thrusters. To compensate for the complexity, you could add "stabilize" which automatically stops any rotation. The uptick of all this would be pretty cool space maneuvering a la battlestar galactica.

If you have ever wanted to live in Firefly, this is the game for you.

I can not beleive how fun this game is. This game is exactly what my friends and I were looking for. The ultimate team work game. I really hope this game gets lots of players so that it will continue to deliver more content. Thus far they have gone above and beyond expectations.

Product received for free
TL:DR at bottom

First I'd like to say, I applaud the developers. This game is pretty damn amazing, even being in early access. It is definitely a game for fans of shows/games like Star Trek that have multiple distinct roles for people to fill. The gameplay and content just in this early access is phenomenal. With that said, I'll give you a list of my pros and cons! I will be assuming a five player crew in most of the points with a few exceptions that I'll point out.


1] First off are the positions that you can take on the ship. Taking a class is truly defining what you do and actually see in the game. Each of the roles is specific and has talent points that enhance their ability to perform their station. During the game, as you go to planets you can pick up research materials lying around that will allow you to research additional bonuses that your crew can spend talent points one. Note, not all research is for the entire crew, some are role specific, but can offer bigger bonuses compared to the all around researchable skills.

2] Next is the universe. . . It's pretty huge tbh. Now, a lot of people are going to say that the stars and whatnot get reused occasionally and honestly, they'd be right. Honestly though, out of the near 20 hours I've been playing, it has never ceased to amaze me with how beautiful space is.

3] The space battles. These are pretty cool, especially some of the tougher fights where you're fighting 3 or more opponents. There are different types of lasers that also have a noticably different color and it makes a spectacular light show that is just amazing to watch. Not to mention you can just feel the ship rumble when the man turret fires lighting your enemy into a bright explosion of debris.

I wasn't sure if I was going to add this to the list but there are a couple that I had though about that were a little hit or miss for me.

1] Lighting is a little odd. Now the hull of the ship when lasers are flying by or the star is gently glinting off the ship, all of that looks phenomenal. But at the same time, there is a little problem with the interior lighting that sometimes bugs me. There are places on the ship that even if you have the interior lights turned on, are WAY too dark to see, even using the flashlight. I find these a little troubling because when I think of space age ships, I'm thinking of REALLY brightly lit ships so you can actually see where you're going or if you have a helmet, it outlines the edges of the ship so you know exactly where objects are.

2] Planets are a little small for how big they look out the viewport. I do understand that the developers want to keep you near where stuff actually is on the planet. But the way the developers keep you from just wandering into some crazy wilderness is either by a radiation wall which, if you pass it, will slowly kill you unless you return. Or by having a giant sand critter pop out of the ground to instant nibble on your gibblets. The flipside though, is that the planets themselves look fairly well made. They may need a bit of polish to be sure, but this is early access.

3] The faction system is a nice idea, but i feel at the moment it's a bit to sensitive as well as unused for the most part. I think the only thing that has happened by screwing rep up is giving me a reason to avoid going to ship investigation sites.


1] First up here is the price. At the moment I would recommend waiting for either a sale or something similar before purchasing a copy as I feel, atm 25 dollars is too high. While it may be a great price for it when it goes and releases, atm it's a bit too steep with unfinished content. (Yes I know i received it for free)

2] Next are the bots. At the moment, the npcs (usually the ones with weapons not the little bug things) are exceptionally accurate, yours AND the enemies. This makes trying to either take a ship or clear a facility on a planet just a little bit frustrating. You'll eventually get it done, but it might take you 2-4 tries just to knock out all the enemies because of the pinpoint accuracy.

3] Last is honestly the textures for the characters themselves. To be honest to is just a minor gripe but I feel as if the developers decided to wait before they update the models.

I definitely love the feel of the game, and playing it with 4 other friends is just an amazing experience. There are also a good amount of games that are on the list that are doing roleplay sessions which I can't help but imagine they're amazing.

Overall, I'd rate this game a 7/10 AT THIS MOMENT. The game definitely has potential, and is a definite must buy if it's during a sale. Otherwise, keep an eye on the game as it develops and offer these developers as much support as possible.

TL:DR; 7/10, great potential, buy during sale, or if you have 4 other friends to jump into the game with you.
