Well at the end of the game its over so if you do not do all of the side quests, which unlock weapons and vehicles, you cannot go back and do them. So if you are an achievement collector I would do them all before act 5.

That's weird I looked on the internet about this and so far can't find nothing about this, Ubisoft is known for allowing you to free roam after the main story is completed.

I guess i'll have to finish the game to see for myself, If you can't continue free roam after the main story then maybe I should of got it for ps4 instead so I can trade it in after i'm done completing it.

there is free roam after completion

Spoiler:

Yeah my game just sits at the end viewing the city skyline.
I will have to reply act 5 and try that.

i reached the end of the fifth act and saved three times.
one right at the decision, one alive and one dead.
both outcomes left me able to roam the streets of chicago.

i put all three into a 7zip file and uploaded them to datafilehost.com: Link

created with the original retail uplay version of the game with season pass. (wearing the 1920 Gangster Outfit)
everything unlocked except for 8 music tracks, and i didn't finish the drinking-, shell-, and one-armed-bandit mini-games.

the drinking game is hard, for the achievement is necessary win at level 10 all 3 challengers.

i don't know.
it's more tedious than hard. once you win a round, you have wo wait a minute or more to play again.

as i looked over the stuff i have and haven't, i noticed i'm missing 2 cars.
the LE variant of one of the performance cars and one of the cheapo-cars.
i don't know where to find those.

and i don't have a clue where to find all the music tracks i'm missing.
rolled through the streets at a snails pace hacking all the people highlighted in blue, but only came across tons of money, which i don't need.

i think i'll invest some more time and get all the missing stuff.
and then i'll submit my save for the page. =)
