"Assassin's Creed IV: Black Flag" lead designer Jean-Sebatien Decant finally answers the most asked questions about the new title's gameplay: how long will it be?

In an interview with the official PlayStation Magazine, Decant revealed the upcoming installment will have a total of 80 hours worth of gameplay. The breakdown of "Assassin's Creed 4" goes as followed: 20 hours to complete main story, 60 hours of open world gameplay.

The "Assassin's Creed" series has always given players a lot of options for exploring their open worlds. Check out what else Decant revealed in his OPM interview below:

Decant's opinion of "Assassin's Creed 4:"

"I think we have to consider 'Assassin's Creed 4: Black Flag' as a new beginning for 'Assassin's Creed.' And we took the opportunity to redefine what we were doing with the present day. And with Desmond dead, we decided to go for something different. [And we wanted to] put it in perspective with what we do at Ubisoft... so: Abstergo, you walk in that building, it's a bit like walking into Ubisoft... we wanted to offer to the fans a way to dig into the mysteries of Assassin's Creed and the templars."

Decant explains how gameplay works:

"So basically, at any time you can exit the Animus and get off your desk and start walking around. You have a device which can hack machines around you. So that's the open-world part. And as for the mystery, throughout the game, many times, a few hundred times, you have moments that are narrative-based, we tell you something about being a researcher at Abstergo, your hacking capacities and so on..."

How to upgrade your ship: 

"Basically you have three systems. You can choose weapons and costumes in the stores, you can improve your character - the health bar and number of potions or guns you can carry - through hunting. Then plundering for cargo, this is for the ship to be able to sail anywhere."
