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.

Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated August 30, 2026.
