I was playing Tomb Raider Anniversary on the PS3 (the HD trilogy version), I played the game on the Hard difficulty and reached the Greece's boss. I quit the game before finishing the boss and played a level by replaying it and chose the Easy difficulty. Afterwards I came back to my save, finished the boss and continued playing through the game.
When I finished the game though, I didn't get the trophy Hard Enough for completing the game on hard (I did get the Sweet Victory trophy for completing the game), which led me to believe my one level as easy changed the difficulty for the rest of my game.
No I face a tough situation, I can replay each levels from the last Greece level onwards on hard, but I don't know if playing the levels individually counts, and the game boots you back to the main menu after each level which leads me to question whether it really does. Another option I have is loading my last save before the one I quit to replay a level and complete the game again from that point onwards, but after loading that save I can't really tell what difficulty it's set to.
Is there a way to know which levels I completed on the hard difficulty? Is there a way to tell if my loaded save is on hard? (Perhaps by the damage enemies do). Is there a sure way to get the trophy without deleting my save and starting the game again?
