Building on yesterday's press briefing, Owlcat Games revealed a new trailer for its Mass Effect-style RPG The Expanse: Osiris Reborn during the Xbox Partner Preview showcase, confirming a spring 2027 release window. PR manager Katharina Popp reiterated the studio's limited use of generative AI for prototyping to Eurogamer.
Owlcat Games, known for Warhammer 40,000: Rogue Trader, showcased a trailer for The Expanse: Osiris Reborn—its upcoming RPG based on James S. A. Corey's book series—at the Xbox Partner Preview on March 27, announcing a spring 2027 release. This follows the studio's press briefing the previous day, where it shared details on a closed beta starting April 22 and day-one Game Pass availability. Ahead of the showcase, PR manager Katharina Popp confirmed to Eurogamer the use of generative AI strictly for prototyping and placeholders, which will be replaced by human-made final assets. 'We don’t use it to create any assets that will be in the game,' she said. 'We use it a lot for prototyping, trying things out... They will all be replaced at the end.' Examples include testing 2D images in 3D or color adjustments to speed up technical iteration, but not for writing or voice acting—ensuring the final game is '100 percent human made.' This is Owlcat's second public statement on the topic, after addressing a March 2024 concept artist job listing mentioning AI tools.
