Character creation is simple using the fate core ruleset.
1. Name and high concept. Who are you and what in a few words would you describe yourself as? A dashing rogue? a hardbitten space marine? an academic researcher? a resourceful pioneer? the patrol accepts all who wish to serve and earn their citizenship in defence of the outer worlds.
Your high concept is the first of your aspects.
2. Choose 1 skill at +4, two at +3, three at +2 and four at +1 from the list below.
vehicle handling, engineering, provoke, willpower, physics, biology, athletics, physique, notice, investigation, fighting, shooting, stealth, empathy, deceit, rapport, infiltration(burglary).
3. Optional. Choose up to three other aspects. These are other descriptors about you. These can be invoked by spending a fate point which helps with rolls where being described as that would help in the action you're undertaking. However if being described as that would hinder you in a situation you can have that aspect 'compelled' which negatively effects the roll. However, compels produce fate points which you can use to invoke your 'cool' aspects or the cool parts of aspects. A character who has a mix of weaknesses and strengths will be able to make their strengths effect the dice rolls a lot more than one who just took aspects with no negative sides.
To write good aspects consider situations where it would hinder you and aid you, if it has both, it's probably a good aspect.
That's it. Please note you can do the third step during play, and each time you fill in an aspect you gain a fate point.
