Nvidia has posted the PC requirements for Call of Duty: Ghosts which requires a hefty 50 GB of free HD space to install among other specs which are significanty higher than those needed for last year's Call of Duty: Black Ops 2.
Why the game needs a 50 GB installation is unclear but it may have something to do with Ghosts' increased texture size which allows the game to be displayed at better resolutions on higher monitors.
Earlier, it was revealed that Call of Duty: Ghosts will have dedicated servers across all platforms.
