Oui enfin bon si c'est open world,c'est pas semi,ni demi,ni trois quarts,ni un cinquième,c'est open world quoi.
"I’d say it’s about 95% open. You can go nearly everywhere. If you see a building you can go in it, there are caves to go in, you can swim in and under the sea to find things of interest there. In terms of size it’s around 3-4 times the size of Dead Island’s map. Dead Island was a very flat game, but in Dying Light you can go really high. It’s not only bigger than Dead Island but you also have to take into account that verticality factor as well. "
Juste le début dit tout "A peu près 95% ouvert"
A près à part ça on a aucune information par rapport à ça donc si il a voulu dire autre chose on n'en sait rien.
