Power weapons are a type of advanced hand-to-hand combat weapon taking several forms but utilising the same basic technological principles. When activated the blade of the weapon becomes sheathed in a field of energy which disrupts solid matter, allowing the weapon to easily tear through armour, including even Terminator Armour.
The basic power weapon type (commonly taking the shape of swords and axes) is in use by several races including humans, while specialized types see more exclusive use.
