Burn 5: Enter or leave Hyperspace, at the end of the round. Whilst in Hyperspace, you cannot be targetted by anything, nor target anything. Ships in Hyperspace are treated as "eliminated" when checking for game winners.
Spend 10: Make a separate strength-20 Attack. You may not use this System if you used it in the previous round, and not more than three times per round.
Spend 10, no more than once per round: Neutron Bomb deals 50 Damage to all players (as if Attacking), next round.
At the end of any round, you may jettison a System to prevent all damage that was dealt to your Ship during that round.
