Chance of critical hit: 88% × 25% = 22%.For example, if you have a 88% chance to hit the target, and a 25% critical chance, the percent outcomes are: To determine the latter, multiply the displayed chance to hit by the critical percentage. In Enemy Unknown, the critical percent displayed in-game indicates the chance of a successful hit being critical, not the chance of landing a critical hit against the opponent. Catching a target out of cover (referred to as 'Enemy Exposed' in XC1), or flanking from an unprotected side, increases the chance of a critical hit by 50% in XC1, or 40% in XC2. These include both parties' pertinent traits, abilities, status effects, gene mods, equipment & upgrades, as well as the positioning of the units. A unit's Critical Hit Damage and Critical Hit Chance stats are partially composed of base stats added by the weapon being used, but may vary from encounter to encounter due to many factors established by both the shooter and the target. When firing most weapons, units have a chance to inflict additional damage (about +50% in XC1) upon their opponent with a critical hit.
