Iv'e played a lot of Fallout 3 and NV. But in my first infiltration at the Corvaga plant I fell under atack b pretty much the whole gang.
A new feture that this game has and diddn't think to tell me about was the fact that spotlights can track your movements and sound alarms.
How do you deal with them?
Also I should mention that although I value the stelth aproch I am not very good at it without a high stelth skill or the Chinise Stelth Suit.
