Historically, the single player campaigns in Call of Duty games have never been too long. Well Call of Duty: WWII could have a campaign of a decent length.
A fan on Twitter asked Sledgehammer Games' Glen Schofield about the length of the campaign in Call of Duty: WWII. He wanted to know if the campaign is longer than Advanced Warfare. Schofield replied with: "Yeah, probably, if not a little longer. Depends how you play of course. Veteran is pretty damn hard."
The recent games in the COD series have had campaigns in the seven hour range. It will be great to see if WWII manages to have a single player campaign that lasts between eight to ten hours long.
Not to mention the game will also have a zombies mode and multiplayer for you to get even more hours of fun. Call of Duty: WWII is due out on November 3rd, 2017 worldwide for the PC, PS4 and Xbox One.
