This vehicle is of such a large size and high complexity that it counts as being a different scale than characters or other vehicles. Weapons of smaller scale cannot harm it, and targets and cover of smaller scale have little defence against them. If a weapon with this trait is fired at a normal-sized target, multiply the damage caused by 10.

The TARDIS is Spaceship Scale, and as such its Armour 30 and Hit Capacity works on the same scale. This is an official rule as per one of the writers of The Silurian Age.
