"You never expect something you trust to turn against you." Why yes, that is the definition of trust. I'm sure it sounded cooler in the writer's head.
Snark aside, as a fan of the Call of Duty series' single player campaigns, it's nice to know that Infinity Ward is still putting some effort into the mode more neglected by its players. Astronauts with guns? That one is new. Satellite-based doomsday weaponry? A little Goldeneye-esque, but I'll take it. And of course, the badass Ghosts dog attacks a helicopter, because that is what badass dogs do.
