Sequential combo input is an opt-in accessibility profile that lets a player press authored combo-chord buttons in sequence instead of at the same instant. The default mode is off, so authored simultaneous chords remain unchanged unless the player enables the setting.
The profile id is Input.SequentialCombo.PerPlayer.V2. It persists per player,
applies during startup before gameplay, and is exposed through
Settings.Accessibility.SequentialComboInput with SequentialCombo.Off,
SequentialCombo.TwoButtonChords, and SequentialCombo.AllComboChords.
The authored catalog maps each sequential alternative back to the same action
and command tag as the original chord, preserving authored move outcomes. For
example, SequentialCombo.Throw.LightMedium resolves LightAttack then
MediumAttack to IA_Grapple and Command.SequentialCombo.Grapple.LightMedium
when pressed within the configured frame window.
Enabled modes are ranked and tournament restricted. The resolver rejects ranked or tournament requests while the profile is enabled, preserves move outcomes, and does not alter frame data, damage, invulnerability, or authored competitive timing.
