If there is an method for everytime then I forgot about it.

Also how many routes did this had again? I forgot if it had a mindless corrupted route and a normal corrupted one that still binds them  and the good guy route.

I'm thinking of three. I think  I played this once already.

Okay I can already see this being annoying and saving was?

After you pressed play and after you choose what Grafiks you want you can press f to use Fullscreen. 

Idk why but it doesnt work on the Startscreen.
