Guns

Guns is a Fallout: New Vegas skill. It is the successor to the Small Guns skill of previous Fallout games, though it has inherited some weapons which would have previously been categorized under Big Guns (such as miniguns, but not missile launchers or Gatling lasers).

The skill determines the player's accuracy and damage with every kind of conventional firearm, from pistols and rifles to miniguns. With higher Guns skill the player will be more accurate (have reduced sway with the larger rifles) and deal more damage (100 skill level deals twice the damage compared to 0 skill).

Initial level

 * $$\text{Initial level}=2+(2\times\text{Agility})+\left\lceil\frac{\text{Luck}}{2}\right\rceil$$

Example: A starting Agility of 5 and Luck of 5.
 * $$2+(2\times5)+\left\lceil\frac{5}{2}\right\rceil=15$$
