Each platform measures its own player population.Why that matters
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison. Percentages are shown exactly as each platform publishes them — Pyroblast does not recalculate them or mix player populations together.
How hard is Killing Floor 2?
Where the challenge is: execution — reflexes, timing and precision. You get through it by getting better at playing it — dodges, parries, muscle memory — not by turning up with a smarter build.
Finishing it
Killing Floor 2 has an ending, but nothing in its achievement list marks it clearly enough to trust — so there's no finish rate to show.

How rarity is calculated
Each platform calculates rarity from its own player population. These percentages are shown side by side but are not a controlled comparison.
- Steam — Valve's published global unlock percentage across Steam owners of the game.
- PlayStation — Sony's published earn rate across PlayStation Network players.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
