9.8 demo is launching September 30. For everyone who's been wanting to try the game, here's your chance!
I’ve been working on making the opening hours feel better, from building your first rocket to flying missions and developing new technologies. If you played an earlier build, quite a bit has changed:
Science mode: complete missions and work your way through the technology progression.
Rebuilt rocket editor: an updated interface for putting your vehicles together.
Replay editor: revisit your flights and share them with the world.
Improved physics, lighting, and overall visuals and models.
The demo introduces the beginning of your space programme. You’ll design rockets, test them, learn from the flights that go wrong, and gradually build towards more ambitious missions. The demo has quite a lot of content and ends on your initial boots on the ground missions on the first moon Kite.
I’ll also be sharing a longer gameplay breakdown before release so you can see these changes in action.
Thanks to everyone who has been testing, reporting bugs and following development. It’s helped a lot getting this ready.
Wishlist 9.8 if you haven’t already, and come back on September 30 to try the demo. I’ll post another update here when it’s live.
