Among some of the more specialised weapons developed by the countless Xenos which plague the galaxy, an Accelerated Ionisation Weapon (AIW) is a rarity to behold. They are almost exclusively constructed by the Rixari, although a small handful of other Xenos races have been found to possess these infernal devices. Every race which has produced a form of this weapon is always technologically advanced, as the weapons require both an understanding of, and access to, radioactive substances.
