XCOM TWILIGHT WATCH
Aggravated: Weapons with the aggravated quality deal aggravated damage to targets. Weapons that deal aggravated damage typically have the Armor Piercing and Beam qualities, but any remaining armor is applied as normal. Aggravated attacks also ignore the durability rating of most objects and structures.
Beam: Weapons with the Beam quality ignore the Ballistic rating of the targets armor.
Hardened: Hardened armors are the defensive answer to advanced energy weapons. Hardened armors may apply their Ballistic rating against beam weapons, downgrading lethal to bashing and aggravated damage to lethal. In addition, Hardened armor reduces the Armor Piercing quality of incoming attacks by 1 (or more).
Prototype: Some weapons and devices are still in the testing phase of development, and often display bothersome quirks and defects. The exact nature of the issue varies from device to device, but any equipment with the Prototype quality has at least one significant defect.
