GameZone: 'Call of Duty is multiplayer. Yet for some reason, Activision, year-in and year-out, pushes the single player campaign on us. Despite the pleas for a multiplayer-only version of the game, which many thought would be possible now that games like Titanfall have broken the mold, Activision is sticking to its guns. Call of Duty: Advanced Warfare will have a campaign and based on the actor starring in it -- House of Cards’ Kevin Spacey -- there’s no doubt in my mind that they’ve spent a pretty penny developing it. The big question is will people actually play it?'
