The Curfew is a browser-based adventure game commissioned by Channel 4 as part of a series of free educational games. It aims to raise awareness about civil liberties issues amongst youngsters, but the unnerving tale it tells will appeal to anyone.

Top secret data has fallen into your hands and you're confined to a safe house while your partner in crime distracts the authorities. Your task is to win the trust of the four people in the room and successfully hand off the precious data capsule to the right person. As you speak to each character, their individual story unfolds, painting a disturbing picture of an authoritarian society in which young people are literally branded as second class citizens, and games are sold on street corners with all the cloak-and-dagger secrecy of a drug deal.

There are few puzzles to speak of, and character interaction is confined to a few question and answer sessions in between flash backs. It's more a piece of interactive fiction than a fully featured game, but with an infectious sense of paranoia and a great story, The Curfew is a thought-provoking adventure.
