On the PS3, Just Cause 2 has 3 trophies for finishing the campaign at different difficulty levels:
Top Agent (Bronze): Bonus for completing the game on Normal difficulty. Heroic Agent (Silver): Bonus for compelting the game on Experienced difficulty. Legendary Agent (Gold): Bonus for completing the game on Hardcore difficulty.
Since they say, "Bonus," I was under the impression that none of them were required but harder difficulties will allow you to earn rare-er trophies. But I've finished the game on Normal difficulty and earned all of the other trophies, but I still don't have a platinum.
Do I really have to earn ALL three of these?
