After finishing the game on Normal, you unlock Easy+ and Normal+ modes where you can play through the story again, but keep all purchased powers, completed events, and stats (except deaths and consumed pedestrians).

It also carries over your stat for missions without military alerts, such that if you finish the game on Normal with only 1-2 (or zero) missions without an alert, you can play through the game again and continue your stat such that if you finished on Normal with 2, you'd only need one more on the replay to get the achievement (even if you get it on the same mission).

HINT: Play through as many missions as possible in military uniform. Always try to have a military uniform as your "disguise" and always be wearing it until a mission forces an alert on you.

I had trouble finding an accurate list of missions by number (there are 31, but not all lists were consistent).

On your first time through, the missions you can do without an alert are (taken from Uberschveinen's FAQ at Neoseeker):

Wheels of Chance
Stolen Body
Biological Imperative
First andW Last Things
World Set Free
Things to Come

However, when replaying the game on a "+" mode, you have all your powers and abilities, such as stealth consume, earlier than you otherwise would, making some missions possible.

For example, you can do mission 4 on a replay with stealth consume, but on a first time through you don't yet have the ability and it's impossible.
