Greetings Commanders!

This is a big one. Galactic War — the roguelike campaign at the heart of Titans — has been a single-player experience since day one. Today that changes. You can now take on the galaxy together, with up to 12 players* sharing a single campaign from the first landing to the final boss.

This update has been a long time coming, and one the community has asked for again and again. Thank you for sticking with us and for keeping Galactic War alive all these years. We can't wait to see your Omega battleships tear across the stars.

One galaxy, one team

*player cap can be increased even further with the launch command --local-server-max-players=64

Play it your way

Co-op ships with two control modes so you can run the campaign however your group likes:

Loadouts & tech, together or separate

The galaxy fights back even harder

The enemy doesn't just sit there while you bring friends. The AI scales to match your team:

Want to add friends without cranking the difficulty? Enable "Allow extra players later" to let people drop in without affecting the campaign's scaling.

Drop in, drop out, keep going

How to start

Your favorite mods, fully supported

Co-op isn't just for the base campaign. Community favorites like Bigger Galactic War and Galactic War Overhaul are supported.

Note: all players need to have the same Galactic War mods to play together.

Modders: add "galacticWarMod": true to modinfo.json to mark your mod as a Galactic War mod.

Linux support marches on

Additionally, we continue work on improving Linux support. We're very happy to announce that a significant number of native Linux distros can now once again run the game. While there are still some issues to iron out, we're grateful to the incredible Linux community for providing testing, logs, and an incredible amount of feedback. Without you, we could not have made it this far.

Thank you

The Community Commanders team has expanded significantly since our last Dev Diary, and we are genuinely overwhelmed by all of the support and enthusiasm for the game's future. Huge thanks to all of the volunteers who helped make this a reality. We really hope we can do justice by this incredible game and its even more incredible community. Special shoutout to the Community Commander Diruslupus, who headed this project. He built an ancient mod idea into a fully fledged feature, pouring countless hours into making sure every off-the-cuff remark became an actual feature.

This is by no means the end of our plans. We have a series of major updates in the works, including some major improvements to the system editor. Stay tuned, something dark lurks amongst the stars…
