Damage Modifiers (Apocalypse)

Damage modifiers are a percentage that alter the base damage of any particular damage type. Every unit in the game is assigned an armour class, with each class containing a table of modifiers that determine how well it absorbs the various damage types.

The damage percentages start at 100% for unaltered damage. Values over 100% indicate more damage will be taken, while values under 100% mean less damage is taken.

Each weapon's damage type is listed on its page; for innate weapons, see here.

¹ Android modifiers are unused, as all X-COM Agents (including androids) use the Human/Hybrid modifiers.

² Smoke, Stun Gas, Incendiary, Alien Gas, Toxin A/B/C and the unused Psionic Blast damage types will completely bypass any Personal Disruptor Shield. The code *does* contain damage modifiers for these, but they are not used.

³ There are two types of explosive damage. It is not clear what type #2 is used for, if anything (perhaps exploding environmental objects?).

⁴ Used by the Stun Grapple - Stun Grenades use the "Stun Gas" type. (Psionic stun does not appear to use this table.)

⁵ This category is for the unused weapon, Psi Grenade.

Notes:

• There is also code for a "Dimension Destabilizer" damage type. This weapon was removed during development. It was to be effective exclusively against shields.
