Greetings
I decided to play this game, because I could never do it during the old days. But of course, I've been encountered with many problems.

1- Agent 47 hasn't any chloroforms in his inventory.
2- I can't save the game while in a mission.
3- Many graphic features are unavailable for me.
4- and I don't know how to change difficulty.

Thanks for helping me.

I was going to answer...but then I saw the post date.Eh I am probably talking to myself now.
