Event advertised in-game but not on the website

Hey guys,

I have seen an "advertisement" for an event called "WAR" dated on the 28th of November (today) and i was wondering, as it has no thread or no announcement on the website, is that event a thing and if it actually is, what do i have to do to fulfill the requirements for that event (in-game it just says play A.I. Bot matches).

Thanks for enlightening me on that topic.
