I recently started playing Fallout New Vegas on the PS3. I kicked on hardcoe mode to make the game more difficult and to earn the Trophy for it as well. I started playing the game and as soon as the section popped up to turn hardcoe mode on a box popped up in the upper right hand corner and said you have not earned a trophy. I didnt think nothing of it at first and just continued to play. After i got to Nipton and used science to get EDE up and running a box popped up in the right corner of the scren saying you did not earn a trophy. Now when i looked through the trophys im supposed to get a trophy for getting 1 companion but i did not get it. Id appreciate some help if someone could tell me why this is happening. Is it because of hardcoe mode? am i gonna get all the trophys i earned through the game after i beat it on hardcoe?

In order to get the trophy you have to turn on hardcoe at the very beginning of the game - when it asks you at Doc Mitchell's house.

...something tells me i might've been ninja'd.

That doesn't sound normal.... You should get the trophies as you earn them regardless of whether HC is on or not.

Sense your still so early in the game, I advise starting a new one.

The only other option I can think of is if you transfered a save from one profile to another. (that woul disable trophies)

I get this if i switch saves from one account to another .

I figured out what the problem was. My friend installed the Caravan Pack on my PS3 but since its tied to his PSN ID it disabled the trophys for me till i deleted it.
