Those who passed the game. The others do not see. (The Surge)

How many bosses in the game, 4 big and one bloke in a black Cerberus? In the last location where a freight Elevator for a three floor ride, the third is the train where he was going, and then killed the boss and the end of the game, to train and nepopal, and for one train to pass over all laziness. Where to change coins. Google really did not find anything.

Ps: about the bosses found.
