Under vacuum, I found this tidbit.
’Mechs: If a ’Mech’s head is breached, the pilot is auto
matically killed. Additionally, a life-support critical hit
eliminates the ’Mech’s internal air supply. During the End
Phase of every turn that the ’Mech remains in vacuum,
the pilot takes 1 point of damage. Each point of Life
Support damage requires the pilot to make an immediate
Consciousness Roll. A failure inflicts a point of damage
on the pilot. Until the unit is removed from the game (is
destroyed, the pilot ejects and so on), a Consciousness
Roll must be made at the end of every turn in which the
pilot is active and the Life Support remains damaged.
Every failure inflicts an additional point of damage on
the pilot. For other hits, treat all of a ’Mech’s components
in a breached location as non- functional: none of that
location’s actuators, weapons or other equipment works.
If the breached location contains engine slots, the engine
now functions as if it took as many critical hits as there
were engine critical slots in that location.
Would that mean a CT breach would cause a potential explosion roll.
Guess not. Still worded funny.
Sheets printed as well.
