Asteroid Day

Asteroid Day was an adventure for the Doctor Who Roleplaying Game, included in the sourcebook The Silurian Age.
== Publisher's summary ==
The characters receive an invitation to the first human expedition into Deep Time. It’s the early 21st century and UNIT scientist Dr Mallory Frost has been selected to lead a team back into the late Cretaceous period. But, when the characters arrive, they realise something has gone badly wrong. UNIT have lost contact with the expedition – Dr Frost has vanished into Deep Time.
Unfortunately, something else has come through the other way. A group of Silurians storm the museum, the vanguard of a much larger force. The characters must negotiate with them, work out what happened to Dr Frost and then journey back into the prehistoric past themselves to rescue her. Once there, they discover the truth: a Silurian named Commander Kreston has discovered the time eddy and is planning on leading his warriors to conquer Earth’s present. It’s Asteroid Day – the day the planetoid is due to hit Earth – and the Silurians would rather not stick around to watch the fireworks.
