The Sontaran Experiment

The Doctor, Sarah and Harry have just defeated the insect-like Wirrn aboard Space Station Nerva. The survivors of the human race are in suspended animation aboard the space station and Vira, second-in-command, has asked you to use the station's transmat to beam down to Earth so see if it is habitable after its exposure to solar flares, hundreds of years before.
Do you wish to play as the Doctor, Sarah or Harry?
