Arcade Mode Special Endings

* In order to reach New Challenger CPU Opponent, first make sure your matches are set for three rounds. Then, without continuing, get three Critical-Art finishes before the end of the fourth match. After this, you will face your mid-boss. This can be done on easy difficulty (though I'm unsure if the number requirement for CA finishes is the same on higher difficulties). Perfects are not needed. NOTE: this seems to change based on which character path you take. I'm looking into finalizing specific requirements.

* In order to face Shin Gouki (secret final boss), do not lose any rounds and get at least five Critical-Art finishes (I believe it's five). I'm unsure if he's the secret boss for all games. He can be reached on easy difficulty, though he will be his usual brutal self. If you lose to him, you will still beat arcade mode. You cannot continue versus him if you do lose.

* For the 1 Straight Victory requirements, this means winning matches without losing a round. This cannot be done with one-round matches.

* I do not know how to get the Hell difficulty needed for some of these. I imagine you'll have to beat Hard first. Or Shin Gouki. *shrug*

Missing Endings

Obviously, I'm missing a grand majority of these. I would love submissions. Email works fine. Or, my Reddit profile works too.

Ideally, PS4 captures or high-quality Steam screenshots stored in PNG format are preferred as they are uncompressed. Several of the submitted links beneath are JPG, good enough, but not the best. AG42 sent in instructions for changing Steam settings, in case you don't know how to do that.

Many thanks to everyone who has submitted images. We're getting there!
