Chris Wynn of Epic Games said in an ' interview that the single player campaign of Gears of War 3 will take approximately 10-12 hours, or two hours more than the previous titles in the series, and players will love it surely thanks the beautiful moments that will give. Please note that unlike the first two titles, this time the story was written by Karen Treviss, the same one that made all the novels so far released on the saga and has contributed to some of the comic stories.
