Gosh, I know it feels like this happens every year, but there are some meaningful changes coming to Call of Duty this time. The engine’s been given a proper overhaul and there are new modes that add more weight, more gravitas to the multiplayer. Look, I’m not saying that you, as a perhaps lapsed fan of Call of Duty games who got tired of what seemed like rehashes year on year, should rush out and buy the game on my say so, but I am saying that if you have the time, you should at least give the game’s impending second beta wave a shot.
