JULY 1ST, 2010

We thank everyone for there support for the 'ORION: Source Multiplayer Beta' product. We had an absolute pleasure playing the game with you guys.

We are proud to have been able to develop and release this for free. We have learned a lot and we are dubbing this the 'Social Experiment'. We have obtained a wealth of community feedback regarding the Source Beta and have applied it to our new endeavor, 'ORION: Prelude' - our companies first endeavor.

The Source Multiplayer Beta was shut down on July 1st, 2010. We are currently focused on the brand new independent title.


Spiral Game Studios, Inc is a brand new independet games developer that has spent the last ten years refining and perfecting multiple game series and game designs. Our flagship game series, 'ORION' is at the helm of all of this.

And opens up! We are pleased to announce that ORION: Source Beta is officially Open-Source! We have been talking about this behind doors for a little bit now and it is finally time. We are extremely humbled to how far we have come and without Valve, Source, the Source SDK and the release of the ORION: Source Multiplayer Beta - it wouldn't have been possible.

We would like to give back to the Source Modding Community. You may have noticed our Firearm's acquisition April Fools joke where they featured some of our old dinosaur content in the media - well now you can do the same.

Sadly, we need to make a few disclaimers. First and most importantly - the Source Code. I unfortunately had a hard drive crap out in late 2009. This means that the Source Code included is the source code from roughly 5-6 months before the first public release. So much of it is dated and will probably appear broken, however, after much discussion we figured that someone out there may find some use from it - so we included it anyways.

There is of course bound to be a few glitches here and there. There also may be some missing content. If we stumble upon any additional assets or materials or source code elements, we will make an update and release it. Let us know any problems you may encounter.

This is a (for the most part) un-organized collection of the files. You talented folk will be responsible for decompiling and reconstruction of the files. This is simply our permission to use it in your mods and products - those of which have no financial gain.

If you have any questions or need help with any of the content, we ask that you refer all questions to:

This content is made available for free to all fellow Modders. We hope you enjoy!

You need a full mod related website up, whether its packed with media shots or not has nothing to do with it, forum boards are not counted as a website, they are a part of a website. After doing this within 1 week, please reply to this pm and your mod will be properly authorized on ModDB.

One of the most horrible and painful experiences of my life, a reskin that plays WORSE than the game its reskinning. Orion had potential during its stages as Incoming and Incoming: Source, but Praz decided to scrap all the good and potential progress in exchange for a crappy reskin. This mod died within its first day, and im not talking about its initial unplayable release, this mod well and truly sucks... And dont get me started on the stuck up deluded cunt who owns the company behind this piece…
