Knockabout Action And Adventure is the “default setting” for most Doctor Who adventures. And most roleplaying game sessions. So there isn’t that much that needs to be said here.
Example: The Maelstrom
(A Knockabout Action And Adventure Aliens Of London story)
The travellers, a UNIT fast response team and a group of civilians are caught between an alien marshal and an escaped carnivorous monster on a Dorset peninsula cut off by artificially bad weather. Can they find the monster before it kills again, and deal with the marshal before she calls in an orbital bombardment of the area to save the rest of the world?
