Without spoiling anything, this game has one of my favorite videogame moments of all time. OF ALL TIME.
You walk into a Classical Music House/bar on the resort, there is beer on the table, which you can drink. If you drink it, you get drunk and there's a cool visual effect and Grayson controls like he's drunk. A DJ announces the classic song "Disco Inferno" and you start murdering dudes, drunk, to the real version of Disco Inferno.
