"This mode allows multiple attacks without using the Multiple Attack Minor Action", while Edge Actions mentions "each Edge Action mentions in parentheses what action must be taken at the same time." Based on that, Xenon's interpretation is the same conclusion I reached.
I know I high-hatted my way into the shadows elsewhere, but this one has me curious.
I disagree on this interpretation, in that there is nothing under the Multiple Attack write up on either the minor action page or the combat option page that requires you to spend a multiple attack
minor action for the attack to
qualify as a multiple attack. The Minor Action
enables you to make one, true. But it is not specified as required "in all cases".
Moving on to the description on the combat option page, it states that any time you are getting more than one attack (regardless of how) you are making a Multiple Attack, and it then describes the procedure. Nothing there requires the Minor Acton spend in all cases either. By definition, if you attack more than one target, your attack is a Multiple Attack (proper noun).
Meanwhile, FA is exempt from that singular instance of the minor attack rule that states you must use it. Because any time you make more than one attack it is, by definition, a Multiple Attack (proper noun) per the Combat Options text, it thus qualifies you for using Anticipation. Edge Actions only require you to spend "an action" not a specific type of action, so that doesn't stop you either.
Edge Action are qualified by saying that they can only be spent once per Action you take. However, no matter how many weapons you can activate, its only a Major action to do so
in the case of Full Auto so two FA strikes from two different weapons is only a single Major Action to perform, (meaning Edge spends apply to all such dice rolls where they are not disallowed from doing so another way, such as the Off Hand Penalty).
So said differently, because there is no requirement for a specific action spend in the case of full auto, the limits imposed by the Minor Action type no longer apply. Any kind of attack option that enables you to attack more than once, regardless of how you achieve it, is a Multiple Attack, qualifying you for the Anticipation Edge spend when using Full Auto. There's no gate on this yard.
Now let's add Dual Wielding and Ambidexterity into the mix.
Ambidexterity "removes the penalty" for attacking off hand. Best I can find, the only penalty is the limit on using not being able to use Edge with an off hand weapon. Under Dual Wielding, it states you resolve dual wielding as a Multiple Attack (splitting dice pool between the two weapons). Nothing exempts you from that specific Dual Wielding pool split, so before spending Edge, Ms. Ambidexterity McGunbunny who happens to have 20 dice in her pool would be able to make up to 10 attacks against 10 targets with each hand. 20 dice is attainable right from CharGen with the right build.
Now, since this is a singular attack action, and is a multiple attack by definition, if Ms McGunbunny has 4 Edge, she can use her FULL DICE POOL against all such targets, making this 20 attacks at 20 dice each. No further splitting anywhere, per Anticipation and Ambidexterity.
That's 400 attack dice being rolled, followed by 20 dodge rolls, maybe 20 soak rolls also.
IF she were not Ambidexterous, and spent the Edge, she would only be able to make 10 attacks at 10 dice each with her main hand, and then would have to divvy up the remaining 10 dice against her targets from her secondary hand due to the off hand limitation.
Not that one would allow this just because RAW, but the rules do seem to as I read them.
Have I missed any other rules on any other pages?
