The History Hunt (not one of the Adventure Games) is free from the site and does not need to be downloaded, which is handy. This is what the Beeb had to say:
“The History Hunt stars Karen Gillan as Amy in a series of exclusive, specially shot videos. Your challenge is to help Amy unlock the Doctor's safe and you can find out how and what's at stake on Monday. But if you're successful you'll release a special short story by Paul Cornell, writer of Father's Day, Human Nature and The Family of Blood.
Throughout the quest you'll find out more about the Doctor's friends and places he's visited. Plus, you'll get Amy's unique point of view about some of the amazing people she's met during her adventures with the Time Lord."
