Casualties: Unknown launched its full version on November 9, and its free demo is staying on Steam. You can try Orsoniks’ cave-survival game before paying. It does not make the demo a reliable picture of everything in release 1.0: the developer is leaving it largely unchanged while the paid game gets more layers, characters and different balance.
For prospective buyers, the useful distinction is between testing the basic injury-and-exploration loop and judging the larger game. This is a reported launch guide, not a hands-on review. We have not played the full release or tested its fixes.
What the paid release adds
The 1.0 changelog lists layers 6–11, two additional playable characters, endings, endless mode and prosthetics. Steam’s description lists eleven layers and three characters in total. These are the developer’s stated features, not our own count or a verdict on their quality.
The changes also reach into familiar systems. Orsoniks lists a wider attack hitbox, adjustments to adrenaline and blood pressure, a less punishing amputation minigame and inventory changes intended to keep items from running offscreen. The list includes numerous fixes, but reading patch notes cannot establish whether each repair works in practice.
Already played the demo? Keep the build difference in mind. Its difficulty or interface problems should not automatically be treated as findings about the paid build. Equally, a longer feature list does not establish that the new endings or later layers are satisfying.

What the demo can still tell you
The store describes a survival game built around descending through hostile caverns, crafting tools and managing limb injuries and blood loss. That is the core fit question: do you want survival decisions to include tending wounds and finding resources to keep your character functioning?
In the launch announcement, Orsoniks says the demo will remain available but will not receive further updates, apart from a small text correction and new ePDAs. Demo-save transfer has not been verified. Treat it as a sample to try, not a promised head start in the full game.
One launch-day Steam reviewer, Undertone, describes the medical system as sitting between arcade and advanced simulation, and finds its challenge approachable for their tastes. Their displayed playtime was 2.9 hours when checked on November 10 around 00:20 UTC. That is one short-session account, not evidence of broad consensus or late-game balance.

Price, platform and the remaining limits
At our November 10 check around 00:18 UTC, the U.S. Steam base game cost $19.54 instead of $22.99, with the introductory offer ending November 23. Regional prices differ. Steam lists single-player play, Windows requirements and Valve’s Steam Deck Playable classification; that label is not our performance test. The developer also flags violence, dismemberment, drug use and self-harm themes.

Start with the demo if the medical-survival premise interests you, then judge the paid scope separately. As in our Hull Rupture demo-and-release guide, an available sample is useful without settling every buying question. More indie-game coverage follows the same rule: distinguish what a developer describes from what has actually been tested.
