I've played all the new characters: Vergil, Lady & Trish,
and here's what I've studied from each character...
Trish mainly uses attacks from Sparda; the big sword on
her back, Luce & Ombra; Sparda's guns & Pandora, one of
Dante's new guns...other than that, her Devil Trigger grants
her lightning-based damage. giving her and infinite Devil
Trigger cheat is nessecary.
next is Lady, she uses her bazooka, handguns & shotgun.
and since her character replaces Nero in Nero's missions,
instead of an Exceed gauge for the Red Queen she has a bullet
gauge with 3 hollow hexagons which fill up when holding down
the X/Square button. each hexagon determine how powerful
the charged shot will be...when all 3 are loaded...BOOM!
in addition, replacing the Devil Trigger gauge are hexagonal
slots for Lady's grenades, pressing LB/L1 will allow her to
toss out as many grenades & giving off a large blast radius
based upon how many hexagons are glowing orange.
With that being said, both infinite Exceed & infinite DT
for Lady are needed...that is, if ye wanna blow
up with Lady!~
Now, last but not least...Vergil: Dante's twin brother
& most importantly, the reason WHY we bought this game.
Vergil's gameplay is a mix of Nero's Devil Bringer with
Dante's gameplay & weapon select; armed with Yamato, Beowulf
& Force Edge. compared to how Vergil played in DMC3 Special
Edition, he plays even better...also, in addition of his
existing skills, a new mechanic has been added in the form
of his "Concentration" gauge. when full, his attacks become
more powerful & have more range too...plus he can even pull
off a more powerful Judgment Cut than before.
Anyway, since the trainer's infinite Devil Trigger ONLY
applies to Nero & Dante, and not Vergil...he too will
need an infinite DT cheat, and infinite Concentration
to enhance his attacks. NOTE: the concentration gauge
will deplete if you: get hit, miss while attacking or
even move/dodge too much. I tried using the never hit cheat
with Vergil & although I didn't get hit, my Concentration
meter dropped to zero.
Anyway, I hope this helps.
