Cold Damage
Cold is just the absence of heat, but it hurts when too
much heat is absent, and calling cold “absent heat”
doesn’t make it any less painful. Cold damage is Physical.
Additionally, cold damage can make armor brittle, liquids
freeze, lubricants gum up, etc. Make a simple Armor Test
for anything directly hit. If the armor gets no hits, it breaks
and cannot be used as armor. It can be repaired with the
Building & Repairing rules, p. 145, CRB. In the case of a glitch,
it’s destroyed irreparably. With a critical glitch the armor
breaks irreparably in a dangerous way.
