The Passing also introduces a series of weekly game mode events dubbed "Mutations."  ( 其中 " THE PASSING " 還引入了一系列的新模式，會於每週更新不同的遊戲模式稱為“突變” )

These week-long runs of new gameplay modes range from "Realism Versus" mode to "Chainsaw Massacre," ( 這些為期一周的 新遊戲模式，如: “寫實對抗” 及 “電鋸大屠殺” 等 )

There are over 20 Mutations planned, each playable on all L4D2 Campaigns. ( 會提供超過 20個 "突變" 計劃，可以運行於所有L4D2的戰役。)
