Call of Duty Warzone is a free to play game. It's not on GamePass and it doesn't need Xbox Live Gold either. MW2 and its multiplayer component is not free. You need to buy it if you want to play the single player game or MW2 multiplayer.

Clearing up a misconception, the Activision/Blizzard deal is not about getting more exclusives. TL;DR: A/B deal is about increasing revenue for Xbox, not getting more exclusives. Games like COD or Diablo are never going to be exclusive because they make too much money on other platforms.

It's very scary, but not that graphic; occasionally a character will get shot or harmed by another, but most of the violence in The Terror comes from nature: dying from a great fall, for example, or being frozen alive.

Terror is usually described as the feeling of dread and anticipation that precedes the horrifying experience. By contrast, horror is the feeling of revulsion that usually follows a frightening sight, sound, or otherwise experience.
