KO_OP Announces Young Suns!

KO_OP is proud to present our latest project, Young Suns!

We're excited to announce YOUNG SUNS: a new narrative-rich co-op life sim set on Jupiter. Experience life in an optimistic future full of colorful characters, available now in Game Preview.

You Are What You Have Done for Others

You play as a sundog, one of the few people entrusted with your very own spaceship. The people of Jupiter have recently freed themselves from predatory corporate control, and it’s up to you to help the friendly citizens build a better tomorrow.

Featuring dozens of fully realized characters with unique looks, behaviors, and months of unique daily chats, you’ll learn their stories and help with the many problems faced by those on Jupiter.

There’s a lot of work to be done if we want to make this a better world, and we can’t build the future alone—join us in our Discord to follow Young Suns’ development, participate in the community, and contribute feedback and suggestions.

Your Ship is Your Home

Fly your ship to fantastical planetoids, derelict ruins, and converted stations with a crew of up to three friends, or entirely on your own. At each location, you can dock your ship and set out on foot, exploring the terrain, harvesting alien plants, and recovering lost goods.

Wherever your adventures take you, your ship is your home among the stars—a space to cultivate, make, and repair. Rearrange a messy living room, perfect a reading nook, or place knickknacks in the cockpit. During your travels, you’ll collect souvenirs, furniture, and clothing from the people, flora, and fauna you meet—perfect for showing off to your crew and remembering your journey by.

A Game That Grows Alongside You

Young Suns is in early, active development, playable and fun for its intended pattern of play: checking in for an hour or two a day, building up your perfect ship-home, and making new friends throughout the Jovian System.

While core features are present, many you'd expect are still in development, and some content—especially quest content—has yet to be implemented.
