Ubisoft has published on its official blog an interesting article on Watch Dogs in which Senior Producer Dominic Guay explains some of the mechanisms underlying the title by answering some of the questions that were still pending.

One of the things on which fans are asked most is the level of the city and simulation of what happens around us: how much of what we have seen in past demonstrations is the result of a simulation and what was scriptato? Guay explains that Watch Dogs everything will be simulated, reaching a level of depth and detail never seen in a game of this type. Disrupt that engine is at the core of the game calculates in real time the behaviour of several sub-systems: " in our city we simulate the way people drive cars. Electricity is simulated. The water is simulated. The wind is simulated. Everyone reacts to everything. By interact all these systems, there are always different reactions. "

To better explain the concept, Guay makes us an example of what happens when it starts raining. Citizens open umbrellas and wet surfaces from rain will begin to reflect light differently, as well as the variation of wind will change the angle of the rain. Even the leaves and rubbish on the streets begin to appear weighted by water and soup. According to Guay, are small details like these that make the world of Watch Dogs extremely immersive and realistic.

But the level of simulation of the game does not stop here: all clothes will be inspired to act realistically, so if a strong wind blows will see them come alive as a result and even some close them or deepen citizens to protect themselves better. Similarly, a car accident will create a ripple effect of large proportions will block traffic, motorists begin to sound the Horn or even exit from machines to better understand what happened. Others have been injured in the accident and passersby will call the emergency number to request relief.

The people of Chicago will react realistically to our actions, as Aiden: depending on how we do in the game we will create a reputation that will determine the behaviour of civilians. For example, if we engage in gunfights often shooting at everything and everyone, whenever they see us do something suspicious will be suspicious and will call the police, while leaving us in peace if we decide to keep a low profile.

As for the much-hyped "player invasion" that allows other players to get into our game and vice versa, Guay clarifies that this will happen only if we want it and that in any case we will not see tens of players run scoordinatamente the city: our world can accommodate only one player at a time when this will accept a contract about us, and we will not know until it is acting against us. A player could get into our game and follow us for tens of minutes without which we are acquainted, to then disappear or decide to attack us/hackerarci. Also those who enter our game (so we when we enter into those of others) will always have an anonymous-looking so that it is visually indistinguishable from the inhabitants of the city, unless, of course, does not begin to behave suspiciously. The Producer has also explained that this particular multiplayer will be available only during the free exploration of the city: once you have begun a mission we cannot be disturbed by anyone.

And now we come to what many would like to know: what a difference there will be between the Xbox 360 versions and One ? Guay explains that Disrupt engine was clearly designed with the next-gen in mind, but is also perfectly scalable to adapt to the current console. This means that Xbox 360 gamers won't have to give up any of the features discussed so far as complete simulation of the game world, but of course will have the less richly detailed visuals and effects, as well as see less people and cars crowd the streets. Guay says of course that the ultimate experience you will have on next-gen consoles: " it will be like to zoom to another level of detail. You'll have better shader, a better simulation of wind and water, more particles, atmospheric effects ... Basically all that you may have with greater computing power. "

Watch Dogs is expected on 21 November on Xbox 360 and Xbox One , if the latter is already out obviously.
