2D Boy and Tomorrow Corporation are coming back for one more run, with World of Goo 2 being announced and it looks glorious. They also note it's the "biggest game we've ever made". The original was one of the earliest full indie games to be given a Native Linux version, and to this day is still one of my favourites.
Not much has actually been said about it yet though only that it's big. The first game came out 15 years ago so a lot has changed in that time but I'm definitely excited to learn more.
Check out the first trailer:
Now, while no platforms have been announced yet, here's a fun little titbit for you: in the YouTube trailer description, they note "Video edited with Kdenlive on Linux Mint". Just a little fun thing to see developers using free and open source tools and noting it like so.
It's due to release some time in 2024. Follow on the official website.
