Casualties: Unknown

Casualties: Unknown is a cave-exploration survival simulator from Orsoniks and Oro Interactive. Sent to an alien planet by your captors, you must retrieve lost cargo while descending through eleven increasingly hostile layers. Each expedition puts a disposable test subject against unfamiliar environments and dwindling supplies.

Survival involves more than avoiding enemies. Injuries, infected wounds and blood loss need treatment, while your character’s mood can affect their chances of making it back. Exploration, crafting and resource management underpin the journey into the depths. The PC release arrived on November 9, 2026, and Steam also offers a demo.
