Weapons
Weapons in FOnline: Reloaded are divided, like in the original Fallout, in six skills:
The more you are competent in a skill, the more you will be efficient with a weapon that is related to this skill.
Repairing
Weapons deteriorate when you use them. For info about weapon wearing out and fixing weapons, see Deterioration article.
Disassembling Weapons
Weapons and armors can be disassembled for 20xp by using the science skill on the weapon in your inventory. By disassembling, you can also get some crafting materials that are needed to craft this weapon. Good science skill is required to get anything.
