just finished a playthru on hardcore difficulty. can i start pt 2 and change the difficulty to insanity before eden prime and still get the cheevo at the end for beating insanity?
Some say you can change it before the end of Eden Prime. However to be sure just change it the instant you get control of Shepard on the Normandy at the start of the game.
I did the same, as soon as you leave the cockpit change difficulty.
