Falador Massacre (10th anniversary event)

The Falador Massacre 10 Year Anniversary event began on 6 June 2016, 10 years after the Falador Massacre bug.

Shortly after that day's system update, news events were displayed that stated: "Cursed You is having a 99 construction house party in Rimmington on world 111. He will level in 30 minutes." This was followed shortly by a message: "Bank all your items!!" The initial message was repeated for 20, 10 and 2 minutes. There was a faux house party as the message promised after which the participating players were teleported to Falador. Here a giant NPC called Durial321 with combat level of 321 and a million life points kept appearing periodically. Whenever it was active, players could also attack each other. Deaths were safe.

While Durial321 was not active, players were picked randomly, transformed into a smaller Durial321 and could attack other players.

Green partyhats also appeared on the ground. They cannot be picked up, and attempting to do so resulted in several humorous messages such as:
 * As you touch the partyhat you think to your self...red would suit me better.
 * If you jig three times, go north, go south, tell the player to the left of you that you love them and click on the partyhat again you might be able to pick it up.
 * Keep trying, maybe, just maybe, eventually...it might work.
 * Nope!
 * Not only did he commit a massacre, he littered aswell!
 * Picking up fake partyhats is XP waste.
 * The partyhat slips from your hands, better try again!
 * You firmly grasp the partyhat before falling over and dropping it.
 * You know what, I just don't believe you want this enough...come back when you really want it!
 * You wish!
