From the Back of the Book:
The Masquerade is a revolutionary storytelling game of live-action roleplaying. It is a type of improvisational theater in which you assume the role of a vampire. You determine your character's actions, invent your own lines, and experience the dark passions of your alter ego. Costumes and props are optional, your imagination is all that matters.
Elegantly simple rules allow you to resolve conflicts quickly and easily, without stepping out of character. Though luck always plays a role, no dice or charts are involved.
