There is no fundamentally new gameplay, only details: a grenade launcher, an icebreaker ship with guns on all sides, the ability to leave burning oil on the water. Everything else is the legacy of Black Flag. Except that the setting—cold, snowy and harsh nature—looks great.
What I liked most was the plot: in the past it combined the third, fourth, and even the next fifth. And in the present, it continues the line of Abstergo Entertainment from Black Flag and is even plot-linked with Chronicles. + The developers left us many reminders about the previous parts (for those who are not aware or have forgotten) in the files of the Abstergo company. This part shows us for the first time that assassins also make mistakes and break a lot of wood, and sometimes their struggle for freedom reaches the point of absurdity.
NB! A funny detail: before going to work, the main character adjusts his collar, but it feels like he’s trying to put on a hood for old time’s sake.
In general, a good, but quite another part of AC.
