Will play sound effects when you get a crit, or when you go on a kill streak. You can type /mka to pull up options. most of them work, there could be a tad bit of jank but it works for me with default settings. There are muting options if you want to mute the sound effects, or the emote function.
Ps. The emote function is coded to have a 20% chance to announce when you get a crit, as to avoid spam. you can turn that off with /mka mutecrit.
