我刚去mod网站搜的，你可以去自己去翻译一下

Basically makes new billy a lot better to play as, the mod removes the roar when he initially chainsaw sprints, it reverts some of his add ons like tuned carberator and moonshine and dad's boots, removes overheat orange glow, you still need to remove the overheat particles manually by going into DeadByDaylight\Content\Effects\ParticleSystems\Killer03 and deleting the uasset files or renaming them.

加mod就是改文件，把电锯的数据改的和老版一样，反正我觉得在正常比赛里用是绝对会被封号的，跟开挂一个性质，时间问题。
