Woo, happy Birthday, Party Zone!
Massacre is a fun gamemode, though I don't play it much.
As for the rest of the update, I highly encourage the return of the Extra Points Upgrades (coins take a painfully long time to earn now, see "[Murder] Extra Points Upgrade," a thread created by myself(shameless self promotion yay)), as well as a better version of the game results (end identity list). This new version only shows who the murderer was, and who spawned with the gun. It no longer shows who actually shot the murderer; that is, in my opinion, an important piece of information for the end results.
