Fight or flight!

[ns9559]

How about a moodlet called something like adrenaline rush, that would apply in moments when your colonists are in or witness someone in imminent danger (proximity to an explosion, gunfire, being sent to rescue a colonist, being attacked obviously). It would give a somewhat significant boost to their mood, say around 30-45 points, either until shortly after the threat is dealt with, or after significant amount of time (around a two to three days). During that time the colonist would not be able to sleep or eat, would move faster, be able to carry heavier loads, shoot more quickly, and hit harder. After the moodlet has worn off the colonist would get another moodlet, an adrenalin crash, that would give a negative mood effect relative to the length of the adrenaline rush, which would wear off after they have done something to boost their mood (eat, sleep, have a conversation, etc).
