Vacuum

For astronauts, vacuum is an all-too-familiar and extremely dangerous environment lurking just outside the protective hull of their starship. Vacuum is not just the lack of breathable air; the lack of pressure and extreme heat or cold can cause veins to rupture, blood to boil, and delicate membranes to freeze or tear.

  When exposed to vacuum without protective gear, a character may hold their breath for a number of rounds equal to their Brawn characteristic. Once this number is reached, the character begins suffocating (see Suffocation on page 112). Furthermore, during each round in which a character is exposed to vacuum, they also suffer 3 wounds. When the character exceeds their wound threshold, they are incapacitated and suffer one Critical Injury as usual, plus one additional Critical Injury during each additional round in which they are exposed to vacuum (which likely and quickly results in death). This is in addition to the Critical Injuries they suffer from suffocating.
