A similar system appeared in earlier entries of the series.
According to TheExclusiveAce — a blogger who analyzes the technical details of weapons and gear in Call of Duty and Battlefield — PC players in Battlefield 6 experience noticeably stronger recoil when firing. On PlayStation 5 and Xbox Series X|S, recoil is about 25% lower.
TheExclusiveAce points out this isn’t unique to the sixth installment: weapons also ‘kicked’ harder for keyboard-and-mouse users in Battlefield 5 and Battlefield 2042. The adjustment appears intended to level the playing field in firefights across different platforms.
