Similar to Series 2, there's going to be just 3 figures.
Arno (McFarlane Master Assassin Outfit)
This outfit was designed by Todd McFarlane himself, very happy to see it in figure form now. Collectors who got the code from Series 3's Arno Figure unlocked this outfit in the Assassin's Creed Unity game.
Arno (Eagle Vision)
Not a big fan of the 'Eagle Vision' figures, same for the NECA version but will still be getting it.
The Rogue joins the line. Good to see the guys from the other side getting some love. Again, this is why I'm a big fan of this line. It isn't limited to the 'main' characters or the fan favourites, but everyone who played a vital role in the series are getting the figure treatment.
So, that's it for Series 4. No hesitation for me, will be getting the trio.
A few characters I would like to see in Series 5;
Altair (Old man, as seen in AC Revelations),
Nikolai Orelov (If the license includes him),
Achilles Davenport (AC3 & AC Rogue versions) &
a couple of Templars from Ezio's trilogy.
