The Yappening (Halo: The Master Chief Collection)

The Yappening, also known as The Yappening: Two Yaps This Time, was an April Fools event held on Halo: The Master Chief Collection, starting from April 3, 2019. The Yappening update accompanied a series of regular title update changes for Master Chief Collection, detailed in the same blog post.

Overview
A Halo Waypoint blog post was posted by Yapyap, detailing how the Grunt had remembered the event a year ago, and decided to repeat it. His troops brought him several items (themselves tongue-in-cheek references to existing lore) such as Janus Keys, slipspace flakes, a "Fragment of Divinity" and pistachios, with Yapyap failing to get them to yield any tangible result. Yapyap then destroyed the assembled artifacts with s, resulting in a mysterious voice conferring Yapyap as the true protector of the Mantle, among other grand titles.

The event then sparked a similar series of events internally at 343 Industries, resulting in a dedicated Yappening splash screen, menu art, nameplates and playlist being created inside The Master Chief Collection 2v2 Halo 2 matchmaking. The Yappening playlist consisted of several unique gametypes:
 * Head-pop Party! - SWAT, albeit with the Grunt Birthday Party Skull activated.
 * Yappening Wargames - Fiesta Slayer, with the additional effect of randomly removing a random heads-up display element on respawn. Each round fired in a weapon fires two ammunition per shot.
 * Brute Shoot - Players have Brute Shots with bottomless magazine and physics from projectiles and explosives are magnified.
 * Methane Moshpit - King of the Hill with all players given high health and needlers with bottomless magazines, with the intention being to use supercombine explosions to push players out of the hill.
 * Yapyap's Ball Grab - Oddball with rocket launchers.
 * Beamish Bonanza - A "big team invisible low gravity SWAT vehicle fiesta mode" - players have no shields, active camouflage, a battle rifle, random secondary weapon and a randomized vehicle set.

The Yappening nameplates were unlocked as follows;


 * Yapyap THE DESTROYER - Complete seven social matches in the Yappening playlist.


 * Shut Your Yap - Headshot 250 Grunts on Heroic difficulty or higher in campaign or Spartan Ops.
