In Riot's anniversary celebration stream, for a moment you can see a monitor that has a cinematic playing, we have never seen this cinematic before: https://media.discordapp.net/attachments/265575789892861952/634319299997073408/Screenshot_from_2019-10-17_11-17-46.png?width=841&height=474

It has Shen and Akali fighting some sort of creature, Shen also gives a thumbs up to Akali.

It could also be some sort of teaser for that PROJECT F game. What do you guys think?
