CoD is terrible, like literally the worst thing ever, please don't try to imitate it again.
Include basic features like A BLOODY FOV SETTING IN THE OPTIONS MENU if you want your pc port to be taken seriously. We sit less then a meter away from our monitors, so don't have the default fov be suitable for a person sitting on a couch across the room from a TV. Peripheral vision is sixy.
Remember the things that made the original in the series a great game - wide open levels, allowing for exploration and choice when approaching an objective.
Just wanted to say that.
Edit: Forgot to mention LEAN. LEANING IS PRETTY COOL, and far superior to the context sensitive cover shooting crap in C2.
