Melee Weapons include all close-quarters hand-held weapons. Many traditional melee weapons, such as swords, have come back into use because modern variants with attack modifiers like armour piercing blades are effective against modern armour. Small, light weapons like a knife or dagger usually do +1PS. Heavier or specialized weapons such as a katana may do +3PS. Using modern advanced materials can add +1PS to the damage done, as well as adding other attack modifiers.
