🧪 How to join the playtest?[/h2]
The closed playtest runs from today till December 8th. To join, just head over to our Steam page and click “Request Access.” It’s that easy—and yes, it’s 100% free!

🎮 What’s in the Playtest?[/h2]
The StarRupture Co-op Playtest features an early slice of the game, featuring the game's core mechanics, a guided tutorial (in single-player mode), and a free play option with map restrictions.
Some gameplay mechanics and more advanced progression levels will be locked out for now (and left for you to fully explore when the game launches in Early Access on January 6th, 2026), so don’t worry about the spoilers; the game will have plenty of fresh and new elements once it launches!
The Co-op Playtest features a more polished experience than July’s Single-Player Round Playtest: we’ve tweaked the performance, ironed out a lot of gameplay mechanics, and we’ve squished a lot of bugs (tons of Vermin were harmed during our internal playtesting), and yes: the autosave is working now!
Your feedback on the playtest will be really helpful for us to deliver you the best possible experience on the Early Access launch -
you can fill out our short feedback form over here.
There is no time limit on your session—play as much (or as little) as you want! However, this event will be limited only by the good old calendar - it will finish on December 8th.

🤝Meet our (anti)heroes[/h2]
During the Co-op Playtest, you will be able to try out in action all of our 4 (anti)heroes - each with their own backstory, traits, and character. They will have plenty of chances to speak with GAL and each other to comment on the current situation. Be sure to try out each one of them to see who is your favorite, before the game launches in Early Access ;)

🧠 The Big Goal[/h2]
This playtest focuses on the online aspect of the game: play online with your local buddies or friends from faraway countries. No worries, though. You still will be able to experience it in single-player, just remember that your saves won’t be compatible with saves from the previous playtest, nor will they be compatible with the Early Access build.
You will help us greatly by completing
the feedback form available at the link.
