I have played this game in single player mode on my PC(specs below), overall experience is good and I am impressed with story line and graphics.
I am highly impressed with how the game starts and tells us the background story of Ghosts. Game play allows us to change role from OP to dog in some scenes, game play varies from space station to ground .
As always it happens with Call of Duty series, couple of scenes looks like just repetition of some other previous COD game or similar to same game scenes, but that just goes with story and doesn’t feel like forceful implementation.
PC Specs:
Intel i5, 8 GB RAM, Nvidea 820m with 2 GB RAM dedicated graphics card.
