O/S Upgrade increases the damage of ranged weapons by 35%, not 15% as the tooltip indicates. This is because Lethal Weapon and Sharpshooter are tied to the same value in the original game.
- Essential upgrade for character builds focusing on ranged weapons. Unless you are strongly specialized in hand-to-hand or Psionic Ability combat, this is an excellent OS upgrade. It affects all non-psionic ranged weapons, so a wide variety of characters can benefit from it.
