Minimum on the Steam store: 4 GB of memory, Integrated GPU, 297 MB of storage. Windows only.

Now with over 600,000 copies sold, ZERO Sievert is a tense top-down extraction shooter that challenges you to scavenge a procedurally-generated wasteland, loot gear, and explore what’s left of a devastated world. When the odds are stacked against you, you’ll need to do more than just survive...

What drives the score

How to read this

Grades run S to D, read from the buyer's side. ▲ marks a lift, ▼ a drag or a dock, ? an input we do not have, • a fact this genre's score does not use. How the grades work

Checked: no in-game purchases or loot boxes. That earns a small credit unless Steam lists in-app purchases

The value story

August 2026 is where it bottomed out, at $11.99. Its cuts run 20 percent off as a rule. There have been 26 in the 4 years tracked, about 7 weeks apart. Today it is at full price, and its last discount ended about 5 weeks ago.

Value puts it in the top 15 percent of the games it competes with. It is pricier than 67 percent of its genre, and better reviewed than 66 percent. Among the games that feel like it, Into the Radius VR ($29.99, scores 80) beats it on value, while it beats Hell is Others ($14.99, scores 39).

Of the 800 Steam-purchase reviews this site sampled, 25 come from buyers who refunded the game, sampled from reviews written June 2025 to September 2026. That is more refunded reviewers than 7 in 10 paid games this site has sampled to the same depth, and among the 1,071 games in its genre sampled this deeply, 228 have a larger share. Inside the two-hour refund window, 58 percent of the 1,241 reviews written there were positive, against 85 percent overall, and those are 9 percent of everything written about it.

It carries Valve's Deck Verified rating, which is the one that means it just works.
