So, I finally finished my first play-through on “Experienced” (I know, I know…work's been crazy and I haven't been able to play much), and I'm eager to start again on “Professional” (got to practice before I go on Xbox Live and get my butt kicked!).
If I want the achievement for finishing the game on a harder difficulty, can I just choose to “Replay Mission” at the first level and change the setting there, or do I have to start a new career? I don't want to lose all my scans, if I can help it.
Thanks muchly!

P.S. This game rocks.
