I didnt realized that it required to hearing things that ur enemies appears from invisible so u have to scan it and shoot it. I dont know if u have to do that all the way to end? The only plm is I cant hear at all. Im deaf. What can I do? I have it but I didnt play it yet.

Well, it answered my question that I posted it eariler today. Im right about required to hear their heaven smiley laughter and scanned it to kill. Its quite bit confusing to start playing this game but Im still hanging it there. Any advices of this? Btw, its difficult to play since I cant able to hear.

Well first of all, the ONLY indication of an appearing heaven smile is their laughter. I have finished the game and this is continuously till the end. You hear laughter you scan, you see heaven smile you shoot. This is the only way.

So I think you would have a big problem playing the game.
I can't think of any tips you can use either.

Sorry

Yeah I have a plm with that but Im still playing this game.
