Hey everybody!
I bought Call of Duty: Ghosts on PlayStation 4 a few weeks ago and it's all fun (never played it before, neither on the PlayStation 3).
The trophies seem quite easy, as I've already earned all the campaign-related trophies.
Now I'm playing the Alien Extinction mode, finished it for the first time in order to get to know the game, and now trying to earn the trophies for this mode. I'm playing it offline-solo on casual difficulty. The weird thing is, I searched the trophies on the internet (they're hidden trophies), and realized that I had to earn some on my first playthrough, and I didn't, not even one. You get Made It Out Alive, Cabin Fever and City Dweller trophies by just playing and finishing the mode, which I did, and I didn't get them. I've just finished the mode for the second time and attempted to reach the chopper with a minute and a half on the clock for the Sprinter trophy; finished it with 1:40 on the clock and still, no trophy.
Anyone knows what the problem is? Please help
