Great theme, starts with a really good piano chord followed by creepy choral pieces and some percussion and guitar before the synthesizer kicks in to give it a real nice 80s sci-fi beat which sets well with a game that deals with some creepy trout set in a setting inspired by 80s cyber punk. Though if I am going to be fair, the series as a whole has always had great main themes.

The new entry has a pretty great central theme as well.
