All in all, simply a great game. The atmosphere is slightly better in AvP 2 due to its radar sound.
Other than that, was it scary? I'm not sure, maybe I'm too old for being scary. Creepy? Yes indeed. Any panic attacks? They are coming for you, run! Atmosphere is great in this game. I think that Isaac should have had some lines for some situations and definitely in the battle.
