I thought Overwatch's new Arcade mode was a glitch, but it's actually a ridiculous cat-stuffed free-for-all where spamming 'meow' is mandatory

Upon opening Overwatch to do my lunchtime dailies (this sans-2 reboot has truly rotted my brain and returned me to my 2016 lifestyle) I had a little poke around the menus to see the addition of a very bizarre Arcade mode: ;ASKLDFAL;S C;A.

Did someone at Blizzard Team 4 goof? Has a line of code caused a little hiccup somewhere, showing me this bizarre amalgamation of characters instead of whatever this mystery mode is supposed to be called? Oh, wait, nope. It's an incredibly silly 6v6 mode...
