First there was the Exodus – when survivors of a great war left the ruins of the Galactic Core behind in search of a new home in the stars. Scattered worlds were claimed on the fringe of the galaxy. Each pocket of survivors held on to an isolated set of worlds while trying to rebuild under the great law of Shalun. Three centuries later, technology has brought them back together again. Discovery of the hyperwarp has bridged what was once an unimaginable distance between far-flung colonies, long-lost families, and political factions.

With that reunification has come great economic prosperity. The hyperwarp reestablished the transportation of cargo, goods, and technologies between the quadrants – but it has also brought great strife. Political rivalries have been rekindled, blood has been shed in age-old feuds, and the fires of war have been stoked. Amidst the political infighting, a ruthless revolution is rising – and the fervent explorers of the hyperwarp have awoken something that was better left asleep.

Our original game, Star Traders RPG, took hundreds of thousands of gamers on an interstellar adventure. Star Traders’ success and overwhelmingly positive reception helped to launch Trese Brothers Games. It was the adventures of our community’s star-crossed captains that put us on a trajectory to share more of our worlds, ideas, and dreams.

We set out to capture the loneliness, bravery, and camaraderie of people living together in a spaceship sailing across the stars. It is with great pride that after releasing four other games in the Star Traders universe, we’ve created a sequel to the original Star Traders RPG.

Step onto the bridge of your starship, take to the stars, and create your own story in Star Traders: Frontiers.

Major Milestone CARTOGRAPHER adds map seeds v2 to the map generator as a new option. These new maps feature better balance, more variety and up to 60 max quadrants. Within the quadrants themselves, we've improved the variety of the maps to include both quadrants that are much larger and harder to traverse as well as those that are even denser. The changes are a roll-up of all the feedback we've gathered from 3 years and hundreds of thousands of maps generated with v1. It is hard to summarize them all, except to say that map v2 are going to create more exciting, more varied and (if you configure it) larger galaxies.

It is critical to say up front that you can keep playing all of your captains who are on v1 maps. You can also keep starting new games on v1 maps you love. If you create new maps in v2, they will come with all the improvements but ALL of our updates are always fully backwards compatible so there is no concern of invalidated saved games or any of those amateur-hour shenanigans.

Before we tell you more: Steam Noms & Wish Knights

It is also that special season of the year when Steam asks us all to nominate amazing games that we love. This year, we're going up for Labor of Love and hope you'll join in by nominating us!

Steam LaborOfLove Banner

And if word hasn't trickled down from the tippity top of the New Boston spires, leaked below the streets and drip-drip-dripped into your safehouse, we're here to tell you about our upcoming turn-based cyberpunk heist RPG. Cyber Knights: Flashpoint will be coming to Steam in 2021 and mixes stealth, hacking and tactical combat with deep RPG elements and a unique heist system for missions. The wishlist button is calling your name, Knight. If you didn't know, now you know.

Create New V2 Maps

Just make sure the "Use Map v2 Generator" checkbox is enabled when create a new map to use all the new map proc gen rules and content. You can still create v1 maps by unchecking the box.

Map Preview

V2 Map Preview Summary

Joining map seeds v2 in Update #240 is the all new map preview feature set. When you are browsing maps you can now see a quick summary of the details for that map, including the counts of how many quadrants each faction owns as well as the total zone count for each faction.

If you need to know more, you can pop open the map preview from within the map list and take a spin around the map without needing to start a new game. This map preview includes everything you need to know, showing all the gates, quadrants, systems and their zones as well as all the stats. You can filter and sort the data just as you would in the game. Finally, this display also highlights the starting quadrant for each faction so you can look and see exactly where you'd get going (and what Danger you'd find) if you started as Javat versus Thulun.

For map grinders, this is really exciting. If you're looking for a certain structure, something new and original, or a map that is tilted toward a certain faction you can now grind and examine maps far more quickly and enjoyably.

Default Map for V2

Small V2 Map

We have decided not to roll out a default map for map seed v2 yet. If you start a new game and use the default map, you will start on the map v1 default map. We are putting out a call to all captains to suggest seeds for the default map. The default map for v1 was discovered in this way during the game's alpha, found and promoted by some enterprising captains.

Please share the coolest seeds you find on the Map V2 Seed Exchange thread and post your seeds that could be candidates for the v2 default map to the Default Map V2 thread.
