Animal (DX)

Animals of various types appear in Deus Ex. Animals include transgenic creatures, such as Greasels, as well as ordinary animals such as cats and dogs. Animals are one of five general types of game entities with scripted AI, the others being robots and the three base classes of non-player characters.

Overview
Animals are divided into hostile and non-hostile types. Hostile animals pose a threat to the player. All but one type of hostile animals are transgenic. Non-hostile animals are either neutral by default or do not possess any attacks at all.

Animals have immunities to certain specific damage types:


 * Transgenics have full immunity to Stunned (riot prod), TearGas (pepper gun and gas grenade), HalonGas (fire extinguisher), and PoisonGas (from poisonous barrels and other environment features) damage.
 * Grays additionally have full immunity to the Radiation, Flamed, and Burned damage types.
 * Non-transgenics receive no health damage from Stunned, TearGas, and HalonGas damage. However, these damage types will cause the animal to flee.

Similar to robots, animals have a single health counter, and do not have health counters for individual body parts as do human NPCs. Damage multipliers that apply to human NPCs, such as the headshot and stealth multipliers, do not apply to animals.

Unlike human NPCs, animals cannot be rendered unconscious by non-lethal weapons. Non-lethal damage from the baton or the mini-crossbow's tranquilizer dart will cause the animal to die, instead of rendering it unconscious.

List of animals

 * * The Gray inflicts radiation damage over a predefined radius. This damage mechanism is hard-coded and is not implemented as a weapon.
 * ** The Cat is equipped with the weapon WeaponCatScratch, but the game script does not provide for the use of this weapon.
 * *** A corresponding attack (WeaponRatBite) exists in the game files but is unused.

Legend


 * Class – The internal class name of the animal. The internal class name is also the identifier used to summon the animal via console commands.
 * HP – The health of the animal, which is the amount of damage that the animal can sustain before being dying.
 * Flee Thld. – The flee threshold. The animal will flee when its health is reduced to the flee threshold.
 * Speed – The speed at which the animal moves. Values listed include GroundSpeed, AirSpeed, and WaterSpeed.
 * Attack – The animal-type weapon that the animal possesses. Attack abilities of animals are implemented in the form of weapons.
 * Collision Size – The collision radius and collision height of the robot. All values are given in Unreal engine units. 16 units is equivalent to 1 feet depicted in-game. Collision height is measured from the vertical center; thus, the total height is double the collision height.
 * Eats – A checkmark (✔) indicates that the animal can eat nearby carcasses. The value in parentheses indicates that amount of health that is regenerated per second when the animal is eating.
 * Flees Player – A checkmark (✔) indicates that the animal will flee from the player, regardless of whether the animal has dropped below the flee threshold. Internally, this parameter is bFleeBigPawns.

Mutt
Mutts are civilian dogs, sometimes kept as pets. Mutts do not attack unless attacked first. Dogs make a barking sound randomly.


 * A mutt can be found with the weapon mods dealer on the ship in the Hong Kong Canals.
 * A mutt can be found in the pet shop in the Wan Chai Market.
 * A named mutt called Starr can be found in the Champs-Élysées, in the arms dealer's apartment.

Cat
Cats are neutral animals. They try to avoid being near the player to avoid being stepped on. Cats have a claw weapon, but the game script does not provide for its use. Cats make a purr sound randomly.


 * A mole person in the Mole People Tunnels has his cat shot by the NSF for trying to escape instead of helping them find ambrosia.
 * Maggie Chow has a hostile cat in her apartment, however it does not attack as it has no weapon.
 * Morgan Everett has a pet cat in his residence.
 * Many cats are owned by Aimee in Denfert-Rochereau, Paris, where some were killed and eaten by greasels in the sewers.

Rat
Rats are found in almost all locations. Like cats, they try to avoid the player to avoid being stepped on. Trashcans and bags have a 50% chance of spawning a rat when destroyed.


 * A Red Arrow member fills the Wan Chai Tea House with rats in order to make them fail their health inspection for paying protection money to the Luminous Path instead.
 * They have an unused weapon that would let them bite enemies.
 * Rats have an unused, unfinished swimming animation.

Pigeon
Pigeons can be found in the cities of New York City, Hong Kong and Paris. When startled by something bigger than them they fly away and after time dive down and land on the ground. Due to poor collision design, their feet appear below the ground while idle. Pigeons coo while idle.

Seagull
Seagulls can only be found in the coastal levels of Liberty Island at the MJ12 Sub Base. Like pigeons, they fly away when startled and their feet appear below the ground when idle. Seagulls cry while idle.

Fly
Flies spawn around trash and dead bodies. Flies have a 10% chance of spawning around trashcans and bags upon level load and have a 20% chance to spawn around dead animals and a 10% chance of spawning around dead humans after 30 seconds.


 * Flies can be killed and spawn more blood than their body size.
 * Flies can enter water without issue.

Fish
Fish can be found in aquatic levels, such as Liberty Island (docks), LaGuardia Airport (dock), the Hong Kong Canals, the Knights Templar Cathedral (in the water under the bridge), Morgan Everett's Home (aquarium), and the Pasadena Ocean Lab.


 * The beige fish has an unused puffed version, possibly intended for when the player got near.
 * The turrets in the Pasadena Ocean Lab may try to shoot fish through the windows, leading to the area seeming more haywire.
 * Fish have no death animation and will disappear when killed.
