A Mass Effect-ish RPG based on The Expanse just makes sense (it's a decent TV show if you haven't seen it, and I've heard good things about the books), and it's cool that a CRPG-focused studio like Owlcat gets to make it. There are some rough edges in the latest trailer, embedded above, and the setting has perhaps transformed a bit to support frequent shootouts, but I like the general shape of what we're seeing.
Owlcat gave us a release window for The Expanse: Osiris Reborn today—spring 2027—and also announced that that those who purchase the $289 physical Collector’s Edition or $80 digital "Miller’s Pack" edition from the official website will get access to a closed beta starting April 22 of this year.
