Your friend gave you a italian copy of this game, so where are you from??
Anyway there is a legal help for you - you have to find someone who wants to translate your version into your native language so you will understand. We have some translated version(dialogue, hints etc. ofcourse) into polish, chinese, etc. but you have to find it usefull for you. So good luck. You had better buy it yourself and play, you will no regret.
