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...
Each input wears a grade, S to D, read from the buyer's side. The color is the direction: green raises the score, red lowers it, grey sits neutral. ▼ marks a dock, ? a missing input, • a fact this genre's score does not use. The exact weights stay secret. These are the inputs and the direction each pushes.
Most players never reach the end. On a 28.6-hour game, that's a lot you pay for and may never use. Steam global achievements
Would refund if I could (got on sale too would still refund), you are required to shoot everything on sight, by the time you figure out if they want to talk to you are probably dead, unable to zoom north/south for reasons? Yet east/west you see more of the map because 'screen ratio', so you ALWAYS have to approach east or west for any engagement or gg, want to shoot someone from max distance? you better have 100...

The lowest price on record is $13.99, set in August 2025. It has been discounted 25 times in the 4 years tracked here, typically at 20 percent off, with about 7 weeks between sales. Today it is at full price. The last sale was about 7 weeks ago, and on this game's rhythm the next one tends to arrive within 7 weeks.
On value it sits in the top 14 percent of its genre. The games it most resembles do better on the same math: VLADiK BRUTAL ($11.99, scores 69) and Chicken Invaders Universe (free, scores 69) both outscore it.
Steam's global achievement data says about under 1 percent of players ever finish it. On a 28.6-hour game, that is a lot of paid-for hours most people never see. Players rate it 85 percent positive over its lifetime, but the last 30 days run 77 percent. Something recent has soured the room.
