Actually
Grand Labyrinth - Sealed Corridor IS available for use online…
for now.
To select it, highlight it's icon and wait for the timer to run out; the game will then select it automatically…
(This is at least true for Xbox LIVE.)
Speaking of "new" moves, Azwel's 1BB doesn't pop the opponent up and
away like it used to, making my 9B follow up miss (though in the video it seems I got either 2B or standing BB by mistake after the 4A+B counter stun). Likewise, I'm going to have to get used to standing AB stunning the opponent away instead of popping 'em up and away.
On a similar note, I noticed Ivy's standing B+K no longer pops an airborne opponent up and overhead like it used to, instead popping them straight up with Ivy still facing away from them… allowing you to follow up with her away-facing A to get 'em spinning in place and Ivy facing them, following up with any number of attack choices, including 88/22(B) into Serpent's Embrace and finishing with 8B+K, Critical Edge, &c.
If you can get the opponent airborne with her 9B+K, you should be able to potentially take off half of your opponent's life bar like that; with that said, I've yet to try it out online since it involves landing 9B+K in the first place. =Þ
EDIT: So according to this
Reddit thread, apparently going too far in an
SCVI "infinite" stage can cause the characters' health and even the rounds to be reset; considering that Grand Labyrinth isn't
meant to be played outside of Training Mode, I suppose that's something to look out for…
EDIT²: So I did some additional testing and it would appear the 88/22(B) follow up only works if the opponent attempts an Ukemi after that back-facing A spin; otherwise, the opponent just gets knocked away along the ground.
