What the developers have to say:

Why Early Access?

“Early Access allows us to spend more time on features and bug fixes while also listening to player feedback and implementing it before the game moved along too far and the product ends up being no fun.”

Approximately how long will this game be in Early Access?

“Our Goal is to have a finished game towards the end of 2017, but we can't promise that it'll be done by that time exactly.”

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

“The Early Access version is currently in Alpha
Sirius Online is currently in Alpha, which means that many bugs are to be expected, core gameplay elements can change, features are missing or might even be removed and so on. Our plan for the full release is:
  • Cross-Platform (Linux, OSX, Windows)
  • Mouse & Keyboard and Full Controller Support
  • Single- and Multiplayer, Dedicated and Listen Servers
  • Modding Support (Ships, Stations, Planets, Sectors, etc)
  • ... (and more)
This list may change during development and is not final or a promise that any of these will make it in.”

What is the current state of the Early Access version?

“Sirius Online is in Alpha, so bugs, glitches and downtime are to be expected.”

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

“Sirius Online will stay Free To Play and will receive an Ingame Cosmetic Store using Micro-Transactions. Any DLC rewards bought before it is implemented will immediately carry over once it is implemented - rewards will be available forever and will not be removed.”

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

“We actively read reviews, feedback, comments and forum threads and respond to them. If you encounter a bug, have feedback, an idea or a suggestion do tell us and we will happily read and respond to you.”

Dev Blog: Where I’ve Been And What I’ve Done

It’s been a while since the last entry, due to school I had little time to work on Sirius Online and other personal projects. But now that school is on break, I had some time to spend and used it to learn Unreal Engine more and get my personal projects out of the way. I know, I promised it would be done by the end of August, I didn’t know that I’d hit so many bugs in Unreal Engine that I had to wait for to be fixed and that packaging for Steam could become a nightmare for hours.

Anyway, with that out of the way, let me show you something:

While those that follow the DDS YouTube and Twitter channel might have already seen it, this is still the first large step towards the new Sirius Online. The next step is to implement projectiles, health stuff, death and respawning. Probably not in that order, but anyway, I hope that it won’t take as long as this took to do.

Xaymar out.

“Sirius Online will become memorable for all the right reasons.”

“[...] this is very fun and I cant wait to see where it is going to go.”

“I went into this expecting nothing and I got a great early access Freelancer like MMO.”

Attention: Porting to Unreal Engine 4

Sirius Online is currently undergoing a major rewrite to use Unreal Engine 4, which means that our workload pretty much doubled. There are currently two versions of the game, one called 'Classic' which you can play right now and the new one which is hidden inside a special branch. Once development is done, only the Unreal Engine version will remain and the 'Classic' version will be released as Open Source.

If you wish to take a look at the Unreal Engine version right now, we have written a Tutorial on how to unlock it on our Forums:

- Digital Dawn Studios

Sirius Online has a LONG way to go, but the developer is extremely active and always involved with the community. That's right. Developer. One guy is programming this game, which is pretty amazing considering the steady rate of updates hat the game now sees. There is not a whole lot to do right now, but if things continue at their current pace, Sirius Online will become memorable for all the right reasons.

!!! Important !!!
Currently it is not yet a game to play (you can already do some things), it is ALPHA and you should be aware of this. Don't buy it, if you want to play immediately! Buy it if you want to support its development and if you want to play it in future!

I say that, because reading the negativ reviews, it seems, that people do not understand, what early access stands for.

After reading all reviews and every information about the game I decided to buy this game to support its development.

The vision of this game, as I understand when reading about it, is exactly what I am looking for: a space sim with mostly player generated content. A really multiplayer experience in space. If it will be massively multiplayer can not yet be said as this is difficult and expensive to realise. But for the beginning, multiplayer would be enough, at least for me.

It seems, that Sirius Online aims for the missing parts of Elite:Dangerous, namely depth. The PvE (Player versus Environment) of Elite:Dangerous is not enough content on a longer time scale. EVE Online is to much spreadsheet and not enough active action. Sirius Online can be the middle course in between and thats what I am hoping for.

The current client is already very good to handle. Its easy to fly around and controls seems to be on a good balance. Flying around is already fun. Mining is also possible, according to other reviews, but I didn't try. So, the game now has a good base to build the system on top of it and fill everything with the game mechanics. Graphics and sounds are fine too but not yet on a current state of the art but promissing.

When you start the game, be prepared that the developer is somewhere around and talks to you. Giving input or asking questions directly to the developer is very nice and not very often seen. But if this game gains momentum it will be more difficult for him, to be accessible like that. So don't expect this in future.

Promissing game idea and a sound base already available, but yet a lot of things to do. Buy it to help the developer to make it real.

To the developer: Great game, exceptional endurance. Stay on this path and we will be with you. Maybe you should consider to bring some more people into your development.

Id like to preface everything with this: EVERY NEGATIVE REVIEW IS COMPLETELY UNFAIR.

This is a game being coded by ONE individual. For one person, it's pretty outstanding.

It's also EXTREMELY EARLY In developement. NOW. The single person making this game CONSTANTLY streams themselves literally coding and testing the game, so it's FAR from dead, and being in on a well made MMO this early for under a dollar consistently can't be anything but great.

I suggest you buy this game (its only 0.99€) and support its developer who has great ideas and is slowly making this game more and more amazing. I went into this expecting nothing and i got a great early access Freelancer like mmo.
It still has a way to go, but the current path it is on is the right one.

I am really enjoying this game, although I haven't met the developer Dex ingame. I met a fellow player who helped me a lot, he tought me the best places to go to make serious money and the best way to get through the early access at the moment.

The things I was told was:
  1. Fly from the Andromeda Station to Sirius IV (Go past Sirius II, then keep a lookour for Sirius IV and use the raday (shift+v))
  2. As soon as Sirius IV is visible look for GNC15 and head towards it.
  3. Once you've reached it sell all ores in the Market tab (F5).
  4. Next look for an asteroid belt that contains the letters 1982 and head towards it.
  5. Stay on the outer edges on the asteroid belt and mine the smaller asteroids by noclipping inside the astoroid (just fly inside it)
  6. Once your cargo's full return to GNC15 and sell everything, you'll even collect Elitium which is worth the most.
  7. Once everything is sold repeat the steps until you can afford a mining ship (labelled 'M' in the ship section of the market)
  8. You'll be able to store a lot more ore with a mining ship, I recommend the 'Kliper'.
There is also a chance you'll log back into the game with the starting ship and be back at the Andromeda Station, so it's best to save up 500k+ maybe even 1mil so you can easily purchase ships if you die and lose it.

Good luck fellow players, and I can't wait to play this after it's full release!

Honestly? It may not really be worth a purchase at the moment but this is definitely a game worth following at least to see how it turns out. If you played Freelancer and are a fan of the game then you'll most definitely want to check this game out. Plays and feels like it.

While there are quite a lot of bugs and the game is currently bare bones, there is a lot you can forgive it for considering there is only one dev I believe working on it. Considering what you usually expect from Early Access games it plays surprisingly well minus the few bugs in controls and netcode so far seems good. Currently there is only PvP and Mining at the moment, oh and flying into the darkness of space and getting lost. Not much to do, but still at least playable.

So yeah, keep an eye on this one. While it really doesn't have much at the moment to offer, it will be interesting to see what the updates will bring.

Posted: January 7, here is the skinny.

I got this title as a gift. Then I played it and looked up the price. It is one dollar at the time of this review.

ONE DOLLAR. So, ya, it's totally worth it.

The wait for an actual Freelancer style game will be some time. This game has more problems than Carter had pills. I've spent more on Android games that had less, still.

My personal experience may be different than yours but it was this experience that will keep me waiting for updates and eventually a release.

So, my buddy and I got into this game after he gifted it to me and it rapidly became apparant that there was not much to it. You spawn in, there is no map. Most of the keys do nothing. Spacebar to toggle mouse flight. AI that fly's the same way and can be exploited. Mining is super esay. Fly up super close and shoot it till you are full of cargo. No explanations on ships or much of anything in the store. Basically the most basics of all things. Kinda like playing an old school Ninetendo game that was a lot of trial and error.

This is what did it for me. The Developer logs in. Ya, that guy. The one person making this game. He answered all questions we had and told of some of his future plans. He even spawned in a huge Capital craft that made everything else look like a tiny ink blot. His love for this game is apparant and you can honestly feel his passion.

I will stay in the loop and wait until this has some more playability and I would usually tell everyone to run from a title like this but the developer did it for me. My buddy even had framerate issues and the Dev tried to fix it right then and there. The Cap ship was a sight to see and his dreams of future development are astounding.

Get it. Play it.

The developer welcomed me with open arms as I got into the game.
Crashed into a planet and got demolished by space pirates.
The game has a good feel to it, it has massive potential.

Support the project, devs are truly dedicated.

Warning: This game does not have much content at the moment.
Sirius Online is a space shooter game with great potential.
-Combat is skill based.(But a better ship has the advantage ofcourse)
-Dogfights are really fun
-Art style is good
-Lack of content

I am glad that I bought it.

I have to say, I am very pleased with the early development of this game. It is an indy game, with just a few people working on it. And they have been doing great in keeping in touch with the player community. When I first bought the game, my actual intention was to indeed take part early access development stages - not just to "play the game". And I'm still willing to do so. However, a few days after purchase, they took the game offline, but explained it was for good reason; they were updating from the now practically antiquated BlitzBasic3D engine (which I'm familiar with from another piece of software), to the Unreal engine. It took a while, but the whole time, the developers were keeping the player community notified on progress every few weeks. They're doing great, considering it's only a few people working on it. The game seems to be back up now. The tutorial still stalls in progression at the mining and industry section (but you can abort the tutorial if you want). And the chat composition field still doesn't allow backspace. But I'm certain this will be ironed out in due time. The game IS still early access and in development. But the devs are very involved. If you're willing to be part of the efforts to help improve this game beyond this stage, and you're looking for a fun multi-player online space pioneering game, then I highly recommend Sirius Online. Just remember, however, at this point of early development, to be ready for bugs and downtimes. And be sure to let the devs know about any bugs you find.
