The counterpart to Fight, Shoot is the skill of using ranged weaponry, either in a conflict or on targets that don’t actively resist your attempts to shoot them (like a bull’s-eye or the broad side of a barn).
Again, as with Fight, if it’s important to your setting to make a distinction between different types of ranged weaponry, you might separate this out into skills like Bows, Guns, Energy Weapons, etc. Don’t go nuts with this unless it’s key to your game.
Overcome:
Unless, for some reason, you need to demonstrate your Shoot ability in a non-conflict situation, you probably won’t be using this skill for normal obstacles much. Obviously, contests involving Shoot are a popular staple of adventure fiction, and we recommend you look for the opportunity to have them if you have a character who specializes in this.
Create an Advantage:
In physical conflicts, Shoot can be used to perform a wide variety of moves, like trick shots, keeping someone under heavy fire, and the like. In cinematic games, you might even be able to disarm people and pin their sleeves to walls—pretty much anything you’ve seen in an action movie. You could also make the argument for creating aspects based on your knowledge of guns (like placing a Prone to Jams aspect on an opponent’s gun).
Attack:
This skill makes physical attacks. You can make them from up to two zones away, unlike with Fight. (Sometimes the range will change with the weapon.)
Defend:
Shoot is unique in that it doesn’t really have a defense component to it—you’d use Athletics for that. You could use it to lay down some covering fire—which might act as a defense for your allies or provide opposition to someone else’s movement—though it could just as easily be represented by creating an advantage (Covering Fire or Hail of Bullets, for example).
