Last gasp doesn't mention Unwieldy nor the Shoot action. Are you thinking of another card maybe?Beyond the language being different I point to last gasp which spells out that you can use the single attack to use an unwieldy weapon in this instance.
Last Gasp said:Before the fighter is removed from play, they can immediately make an attack. This is a close combat attack if they are Engaged, otherwise it is a ranged attack.
Bond of Brotherhood said:The fighter can immediately make a Fight (basic) or Shoot (basic) action. This is in addition to the two other actions they can make during their turns.
As written, the first clearly let you use Unwieldy weapons, the last one clearly doesn't (unless you have Suspensors or equivalent) and the middle may or may not allow it.Opening Volley said:Choose up to 3 fighters to immediately make a free Shoot (Basic) action. Note that this does not apply if the action would be (Simple) or (Double) for any reason.
I wouldn't be so sure aboute that, they're fully capable of using different wordings on remainders for the same things in a single release.Yeah, that's also where I'm at now. I think they added the note on Opening Volley simply as a reminder/clarification. Bond of Brotherhood would probably have the same note if they released it today.
