I have absolutely no clue whether Hive is planning on doing this already or not, but like Bedwars, you should be able to get hub titles that display your statistics in Murder Mystery
Bedwars, Sg, and Skywars both have statistic hub titles as well with their microhubs (excluding SG), and Murder Mystery should do the same with its microhub. By completing challenges like: Eliminate the murderer 25 times, or Kill 1000 players, you get badges that you accumulate to get prizes. My main point is that Murder Mystery’s new update should be a lot like Bedwars’ update with it’s challenges. Again, Hive might already be doing this, but incase they are not, I think that some hub titles like “X Murder Eliminations”, “X Kills”, “X Victories”, etc.. But yeah that is my suggestion and I think it would be cool to add into the game like Skywars and Bedwars. Thanks!
