Five minutes to launch...
(Rule)Description: A deathstrike missile may not be fired on the first turn of the game or if the vehicle has moved that turn. When firing, roll a dice and apply the following modifiers:
+1 for each full turn
-1 for each weapon destroyed
-1 if crew shaken/stunned
On a roll of 6 or more, the Deathstrike Missile can be fired. A natural roll of 6 will always result in the missile being launched, regardless of negative modifiers.
