Call Of Duty: Ghosts Campaign Is Only 4 Hours Long. Gaming Blend Battlefield 4 has already set the bar pretty low with a campaign mode that clocks in at around four hours, according to most reviews. The story is too old to be commented. I'm calling it, the next COD won't come with a single player campaign.
All Xbox One games have a digital version, unless there's a required physical peripheral (for example, the portal device in Skylanders SWAP Force). It depends on the game. But some games, such as Call of Duty: Ghosts, actually include extra bonuses with digital content that don't come with the disc-based edition of the game. Other titles, such as Dead Rising 3, will have pre-order incentives that come with the digital version for the first two weeks.
