They never said which Call of Duty. There are a couple of Android versions of CoD. You wouldn't want to play them on a big ass TV screen (or at all, really) but they do exist.
It's all just so much marketing anyway. No one ever calls out car makers for ads depicting their new luxury SUVs breaking through some very sturdy looking cement walls because the asterisk (fine print in this case) says "Do not attempt. This is a dramatization." If you're so dumb as to buy into everything you see/read/hear then you've clearly fallen through the cracks of natural selection and the marketers are the predators here to feast on your bones.
