Damage Modifiers (Apocalypse)

A unit's natural or worn armor which is resistant to, or susceptible to, certain effects or damage.

Damage Effects

Ammunition damage effects are catergorised as technologically basic, as in Standard, or as advanced effects in Exotic, which are typically researched or invented technologies. Other damage types are also possible.

Standard

Armor Piercing
An ammunition type based on kinetic force which is applied to a very small spot from a long needle-shaped projectile onto a target allowing it to 'burrow' through the 'skin' (eg: protective armor-plate, vehicle body, carapace, etc.) of the target by the action of momentum.
Explosive
An ammunition type based on producing a fast expanding pressure shockwave which damages anything nearby by concussive force.
Incendiary
An ammunition type based on a thick flammable liquid which is spread over a target by a weak explosive, then ignited to damage anything over short time.
Laser Beam
An ammunition type based on light (photons) concentrated onto an extremely small spot on a target to inflict heat damage and eventual burn-through to 'cook' anything by extreme temperatures.
Plasma
An ammunition type based on localised extreme heat to burn something so quickly that it etches away a target by 'evaporating' its molecular chemistry.

Exotic

Distruptor Beam
An alien energy type based on sub-atomic particles impacting a target to 'disassemble' its molecular chemistry.
Enzyme
An alien corrosive chemical and toxic enzyme mix designed to dissolve metallic items and biological organisms by 'splashing' over a target when the ammunition breaks open from impact.
Anti-Alien Toxins and Anti-Alien Gas
An X-Com developed injectable or aerosolized liquid toxin designed specifically to kill the micronoid organism within the body's of all alien lifeforms.

Non Lethal

Smoke
A natural effect of fire or a purposely designed grenade to spread dense smoke to limit visiblity. Any unprotected unit within a thick cloud will very slowly be overcome and may fall unconscious.
Stun
A type of specific, non-lethal effect designed to incapacitate an entity without causing injury.

Non Weapon

Impact Damage
An effect of the battlescape only. It is either a heavy object (eg: building collapse) falling onto any unit underneath or any unit that has fallen from, or purposely jumped, off an elevated structure of some sort and has impacted the ground.

Damage Modifiers

An entity which has been affected by any of the Damage Effects, listed above, will have a certain percentage rating on how well that unit resisted (low percentages), or how much extra (higher percentage) that unit was affected.

• A damage modifier will always start at 100% since most lifeforms are susceptible to some form of attack.
• X-Com armor can be mixed. A body part which is affected will be using that armor type. Explosives, being area effect will have different percentage values according to any mixed armors and will be calculated as one total to apply to a unit's decrease in health, if any.

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.

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