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.
- Xbox — Microsoft's published rarity percentage across Xbox players.
Percentages are shown exactly as each platform publishes them. Pyroblast does not recalculate them and does not mix player populations together. Data updated .
