UNION is a cooperative spaceship simulator with deep tactical gameplay.


  • Command a spaceship with up to four of your friends in different roles (Captain, Helm, Tactical, Engineering and Science).
  • Work together to survive and conquer in hostile space. Develop your own tactics and team dynamics.
  • Deep emergent gameplay; all systems, from physics to power and heat, are simulated in an integrated environment.
  • Newtonian flight physics with velocity and momentum.
  • Multiplayer ship vs ship combat (each ship with it's own crew of up to five players).

Thank you to everyone who has followed the project here and on my Twitter. I really appreciate it.

I'm still working away on UNION. Not as much as I'd like perhaps, due to work and family commitments, but as much as I can.

Engineering is the beating heart of every ship in UNION, so it is the UI that I have been focusing on the most. I'm finally at a stage where I think it's good enough to show.

UI - Engineering Screen

This is the UI which the ship Engineer will use to manage power and damage control.

Power connections are made from the Core to each system (shields, weapons etc.) by dragging from a Core node (the circles surrounding the Core) to the system.

Hovering over a system, hull segment (the white bars surrounding the "wheel") or shields (the blue bars surrounding the "wheel") will give detailed info on it in the top left (in this image Forward Shields has been hovered over).

Clicking on a system (or hull segment) will show the player options for that item (e.g. power settings, heat/coolant management, repair options).

Presets allow the player to quickly switch between configurations. Two presets are provided by default, Standard and Cruise; other presets can be created by clicking Save beside one of the custom presets.

Heat is one of the most important elements for an Engineer to monitor and manage. Too much heat can damage systems and it also makes your ship easier to detect, lock onto, and hit.

Each system, and the Core, has a stability rating (0% to 100%). This rating is from a combination of the system's heat and the integrity. High heat and low integrity lower the stability of the system. Systems with a low stability are more likely to suffer faults (fire, power surges, explosion), especially when they suffer damage.

The picture above is of the in-game UI, however it is not yet complete. I have to add the elements which will be common to all screens and there is still a lot of programming to do to get everything fully working.

Thank you for taking the time to read my update. I'll try not wait too long before the next.

I'd appreciate any feedback you could give in the comments.

All the best,

Hey all,

I don't want to do a full news post because I'm not ready to post new content yet. I am still working on UNION, however my UNION development time in the last six months has been extremely limited due to work (which has been intensely busy).

I have made significant progress on the ship systems simulation game code (which is networked, like everything else in UNION), I have a new model for the Kite Class ship and it's turrets, there are improvements to the Engineering UI, and I'm working on both the Helm and Tactical UIs.

I don't want to release content (screenshots, videos etc.) until I'm happy with the level of polish, but I will have some for you soon.

Thanks to everyone who has followed UNION, your support means a whole lot to me.

Thank you for the compliments!

There is a lot of depth to the systems in UNION, I am doing my best to make them as intuitive as possible, including providing visual cues where action is required.

Looking great and very ambitious! Following this one for sure. Love Artemis but this is Artemis leveled up!

Artemis inspired me to create UNION, not as a better version of that game but as a very different take on the idea. It has become my passion and I hope that, when it is finally released, people will love it.

I have been working away in the background and will show my progress soon, including a redesigned pretty-much-complete Kite Class ship.

Wish I could code to help you out! Your work is very polished and would love to see where you go with it.

Thank you so much. I'm creating UNION in my spare time, "juggling" it with work and family, and your support is really appreciated.

If you want a military consultant let me know. I can help you with ideas based on my military experience.

#UNION #Helm also handles defensive systems, while #Tactical manages the calibration and (obv) firing of weapons. #spaceship #gamedev

May 10 2014, 11:46am

The #Tactical station locks targets and can use precision scans to detect the heat sigs of the ship's systems, allowing them to be targeted.

May 10 2014, 11:43am

In #UNION the #Helm station finds targets, using scans and probes, then intercepts the target and maneuvers around it for optimal targeting.

I'm working on the #Tactical #UI for #UNION now. I decided to ditch a #Science station and split it's functions between #Helm and #Tactical

Progress on #UNION #Coop #Spaceship #Sim has been slow due to work, but here's the latest shot of the Eng UI #gamedev T.co

@Ragerin I plan to do a limited free alpha for UNION and, all going well, a €5 early access. It's to early to decide on a retail price

@Ragerin Hi Mads, thanks for getting in touch. Still working on #UNION but work is extremely busy so progress is slow.

Mar 6 2014, 5:08am

@ajlitton Hi Anthony. Cool, I've followed you now.

Dec 21 2013, 12:11pm

@Sticky_Brain @FreeCry Hey guys. Just back from a busy weekend, sending on my email address now.
