Hardened is a trait of numerous units that cannot take cover in XCOM: Enemy Unknown.

“	Hardened units receive extra protection against critical hits.	”
– In-Game Description, XCOM: Enemy Unknown

Effect

Reduces the chance of suffering a critical hit by 60%.

Notes

• Berserkers, Chryssalids, Cyberdiscs (in "closed" form), Drones, Ethereals, Sectopods, and the Uber Ethereal all benefit from the Hardened trait.
  • Mechtoids also have this trait in XCOM: Enemy Within.
• All varieties of S.H.I.V.s, as well as MEC Troopers ^EW, are Hardened on the human side.
• The Second Wave option "Absolutely Critical" increases the reduction to -100% to compensate for the increased critical chance against exposed or flanked opponents. This does, however, mean that the Hardened unit does not negate a weapon's base critical chance, like the 10% of assault rifles or 20% of shotguns.
