White Night - Total Conversion v1.1

And I already planned that my story must contains Atleast 50 maps

... Don't do that. I don't even think the main game has that many maps. You'll most likely end up repeating areas, puzzle, scares, etc. And unless you make a custom story that's like 3 times better than the original the player will most likely get bored. I'd say at most have 20 maps but that's even pushing it. Not trying to be mean, just trying to give you some advice
