Life is game, you gotta enjoy the journey.
Life may knock you down sometimes. Its up to you if you stand up and live your life to the fullest.
I have assigned action card, in the assigned phase I must use the action "assigned card" like a mission card (placing a character on there card) or I can use during resolution phase taking a character from the reserve?
In assignment phase you can play action cards that state assignment. You fullfill what it states and continue your assignment.
Then the Empire has his assignment.
Then on to command phase.
