Forum:The hard way achievement

Hy!

I want to get the Hard Way DLC (Shadow Broker) achievement. I want to play the game following the story, so I want to play the Shadow Broker DLC story after the final fight at the Colector base beyond the Omega-4 relay. But I already landed on Illium to complete the recruitment/loylty quests there. I play on normal difficulty. My question comes here: is it enough to set the difficulty to Hardcore/Insanity before I talk with Liara about the Shadow Broker? I already talked with her about the other missions she is involved in. As I read on other forums, other players set the difficulty before landing on Illium to get the achievement, but I already landed there on normal. Will I get the achievement if I enter Liara's apartment (first part of the quest) on Hardcore/Insanity? Thank you for your answer.
