After the recent PROJECT Varus tease on League of Legends social media, it seems they're at it again with another PROJECT skin teased. After some short teases, we have had an official animation released.
The official League of Legends Topic on YouTube has had the icon change to a PROJECT Mordekaiser skin.
It doesn't currently seem to be anywhere else, but there is a PROJECT Mordekaiser post on Reddit from the end of April; obviously ignored but it seems there is now some substance behind the claim. This post also stated that it would come out in May, so we should see the skins come in the next patch or two, if this redditor is correct.
Since these teasers came out, or were noticed, we have had an official animation posted to all social media accounts.
The twenty second video shows the PROJECT Mordekaiser skin within the PROJECT setting, basically confirming the event and the skin.
We haven't had a PROJECT event for a while, the last one was in 2019. This is a usually well received skin line, and each release usually has several additions.
