The higher the number, the more likely
the attack will be successful. No attack can have more than a 95% chance
of success. Your base chance to hit is your weapon skill. This is reduced
by the range penalty, cover (including other people and light terrain
in the way), the base accuracy of the weapon, the stance of the target,
targeted shots, lighting and the armor class of your target. Being Immobile,
Concussed, Winded, Crippled, Withdrawl, Overdose, Blinded, Stunned or
Injured will also reduce your chance to hit. Your chance to hit is improved
by firing at point blank range. The range penalty is offset by a higher
Perception and the weapon's range.
