The passage lasts about 10 hours, with no intention of finishing everything as quickly as possible, but a lot depends on the choice of difficulty (I played on easy). The plot is weak. It is very annoying that the story is shown only from one side of the conflict, one point of view, the plot begins to get especially bad towards the end of the game. And at the same time, Codex of Victory has some good characters and ideas. True, most of them are unsolved, and some plot twists lead to nowhere. The game is good, but towards the end it starts to get boring. Rating 6 out of 10.
P.S. Advice: When the opportunity to level up arises, level up the heroes first.
