Amazon.co.uk Review
In a nutshell: The term "interactive movie" is justly associated with misguided attempts at combining games and film.
Fahrenheits cinematic leanings, however, incorporate the elements that make movies different (characters, tension and plot) with well thought-out game mechanics, and the result is uniquely thrilling.
The lowdown:
Making decisions against a rapidly dwindling timer, your character wakes up having just committed a bizarre ritual murder of which he has no memory. You must switch between playing the fugitive and the cops on his trail, your conflicting jobs are to help the anti-hero escape and conversely to help put him behind bars. But what mysterious force drove him to kill in the first place?
Most exciting moment:
Frequent interludes of rapid button pressing simulate physical exertion as your character escapes a looming threat you can see catching up with you. Your heart will be palpitating. Your nerves will be frayed.
Since you ask:
The introduction and brief tutorial from the games "writer/director" David Cage, is actually the head of the titles French development team, Quantic Dream, animated as a videogame character.
The bottom line:
Utterly superb movie-style thriller with genuine frights and a superbly tense climax.
