“Advance Strike” is a great new way to fend off throws and physical blows, allowing for even more aggressive plays than those possible with Shatter Strikes. This new mechanic costs half a power gauge bar to perform, but you’ll regain that half bar on both hit and block.

An Advance Strike causes a hard knockdown on hit, leaving you well placed for more offense. Unlike Shatter Strikes, the move gains a counter hitbox against throws partway through; if it lands while the counter is active, your opponent will crumple to the ground (and be prone to follow-ups). Use Advance Strikes to bring the fight to your opponent like never before!

The rest of the patch notes follow.

■ SYSTEM XXXXXX
Story ・Resolved an issue where a cutscene (Duo Lon vs Elisabeth) was not playing.
Other ・Resolved minor issues.

■ General
Advance Strike
・Added “Advance Strike,” performed with [↓↙← + HP+HK].
This new attack mechanic helps you fend off enemy throws.
See the “Advance Strike” tutorial explanation for more details.
Shatter Strike
・Increased combo scaling value.
* No change in scaling value when it hits during a combo.
・Made command input window consistent with [↓↘→ + button] Special Moves.
・Raised input priority so that Super Special Moves will not come out unintentionally.
・Made the attack’s active frames consistent for all characters.
* Extended active frames by 1–2F for Ralf Jones, Isla, Ryuji Yamazaki, and Darli
Dagger.
Anywhere Juggles
・Some moves with Anywhere Juggle properties, like Ryo’s Zanretsuken (EX Ver.),
were hitting crumpled opponents (after a Shatter Strike impact, for example)
on the ground unnaturally.
Adjusted for consistency so that the affected moves will no longer hit in this way.

■ KYO KUSANAGI
Shatter Strike
・Resolved an issue where it would pass through opponents under certain
circumstances.

■ ANDY BOGARD
Chou・Shin・Soku・Zan-ei Ken
・Resolved an issue where, under certain circumstances, the move would not catch
the opponent on hit.

■ YURI SAKAZAKI
Tsubame Otoshi
・Resolved an issue where a Tsubame Otoshi performed immediately after attacks
with high combo scaling (such as Blow Backs) would, on successful hit,
deal damage that ignored the scaling value.
* In line with this adjustment, damage when used during regular combos has been
reduced by about 5.

■ RYUJI YAMAZAKI
Todome
・Move was slightly harder to perform than other [→↘↓↙←→ + button] ones.
Made input properties consistent with those of the others.

Drop from Mamahaha (↑ Input) ・Resolved an issue where players could cancel this into the EX version of
Drop from Mamahaha (→ Input).

・Can no longer avoid the Level 3 version of this attack using counter moves or
Guard Points.
