Halo Wars 2


The Yappening is the name of a humorous in-game event held on Halo Wars 2 between March 29 and April 2, 2018. The Yappening is fictionally (albeit non-canonically) framed through the lens of Yapyap the DESTROYER gaining access to 343's servers and using it to wreak havoc in the games. The events typically come with limited-time changes to game functionality, often for comedic effect.

The Yappening, also referred to in the Halo Wars 2 API as Season 9.5, was the by technicality the tenth season of Halo Wars 2 to launch, beginning on March 29, 2018. The season followed Season 9 and was succeeded by Season 10 on April 2, 2018. The season's emblem is represented by a Methane Wagon.

On March 28, 2018, a blog post was submitted to Halo Waypoint by Yapyap, detailing that he had found a Forerunner artifact called the "Key of Balance", which promptly began speaking to him about the responsibility of balance. Yapyap proceeded to talk with the key and eventually destroyed it, using the key to bring about change. This post was updated by Jeff Easterling purporting that the post was not authorized by anyone on the Waypoint team, then later again updated noting that the event had also affected Halo Wars 2 game files, with a list of patch notes detailing the limited-time event changes over the weekend. The effects given initially only affected unit balance, but went on to affect leader powers, skirmish, Terminus Firefight, matchmaking, playlist names and the campaign level Under the Dark. Notably, the changes in particular affected Yapyap's gameplay, giving massive buffs to his units and starting army, culminating in Yapyap being given his own Season.[1][2]
