We support Virtual Reality and will be constantly releasing new experiences within The ORION Project with aims to support multiple VR platforms!

We had a few hiccups along the way. Everything is a learning mistake. This is no different than any other person and the only thing we deem important is how you take it from there.

We've invested years of time and money into our communities and products and we do it because we appreciate any level of support but also because we truly love Orion and will see it through regardless, no matter what.

Everyone is absolutely loving working on Orion and we're all creating the most amazing and enjoyable content in the history of our team.

We want to add more, we want to do it quicker and we want to keep pushing this game past the limits that we initially set back just in December 2015.

We had attempted to do a crowdfunding back in 2014, however that was before we had any playable prototype and was mostly based on the core idea and artwork. This was not a success.
We had attempted to do a crowdfunding back in 2015 WITH a playable prototype. This event failed BUT we still honored ALL Backers with rewards AND released the product on time!

We are willing to work night and day for you, for years. Whether it's investing or simply telling a friend, any little action can snowball into the biggest of possibilities.

We know that because we are examples of that and illustrated this on our first game, ORION: Prelude:

We can only create the game. We need your help to share it.

So we've launched a massive ORION crowdfunding campaign that will offer a wide variety of rewards and packages, both digital and physical. We love ORION very much but we also love the industry in which supports indie endeavors like ORION and constantly fight for it and the gamers that create it.

We want to do so much more with The ORION Project and the focus of this Crowdfunding campaign is to boost production speeds as we approach the massive Version 2.0.

We want to afford existing developers more time, we want to bring on more talent and we want to release content even quicker than we already are.

Got about lots of copies to gift to friends because I was enjoying the game, but then the lack of proper polishing prevented me from gifting those copies that used to cost like 10 dollars each, because I didn't want to look like an idiot who would gift copies of poorly done games. My friends didn't diserve that.
Now it's gone f2p and I'm stuck with those copies for eternity in my inventory as shame badges.
