Editing Half-Life/Enemies

{{Header Nav|game=Half-Life}}

There are a wide variety of enemies you will face in the game, both alien and human. This is a comprehensive list of all the enemies featured in the game as well as their health, damage infliction, and a description. The damage and health are given in the form of three sets of numbers. This is to show the value at the three difficulties. For example, the headcrab's attack is given as 10/10/20. This means that at on easy and medium difficulty, a headcrab attack does 10 damage, while it does 20 on hard difficulty. They are presented in more or less the order in which they are encountered.

==Early Game Enemies==

===Barnacle===
[[File:HLbs_barnacle.png|125px|left]]
*'''Health''': 10/10/10
*'''Damage''': Instant death if manages to pull you up to the top.

Barnacles are stationary aliens that attach to ceilings. They have extremely long and sticky tongues that they hang down from the ceiling. These can be hard to see, especially if the barnacle is stationed up on a high ceiling. If something wanders under the barnacle and touched its tongue, the barnacle will immediately begin reeling it in. If you wander into a barnacle's tongue, the same will happen to you. If you do not kill the barnacle by the time you are sucked into its jaws, you will be instantly killed. Thankfully, however, it only takes one swipe of the [[Half-Life/Weapons#Crowbar|crowbar]] to kill a barnacle, so if you do get caught by one, simply swipe the barnacle when you reach its mouth. This will not save you from falling damage, however. Barnacles will not distinguish between you and an enemy, and can be used as traps to snag [[#Human Grunt|marines]]. The [[Half-Life/Weapons#9mm Pistol|pistol]] or crowbar are recommended for taking out barnacle- anything more powerful is a waste of ammo.

===Headcrab===
[[File:HLbs_headcrab.png|125px|left]]
*'''Health''': 10/10/20
*'''Damage: Jump Attack''': 10/10/20

Headcrabs are the first enemy encountered in the game. They're rather weak, but can be dangerous in groups. Headcrabs are usually found hiding in damp or dark areas, waiting for prey to ambush. When attacking, they launch themselves at their intended victim's head, making a screeching sound. If they successfully attach to an NPC's head, they will dig into its brain and turn it into a zombie (see below). Headcrabs are best taken out at a distance with the [[Half-Life/Weapons#9mm Pistol|pistol]] or, later in the game, the [[Half-Life/Weapons#Hivehand|hivehand]] from a distance. If you are good at dodging their jump attacks or are encountering them in close quarters, you may also choose run up and hit them with the [[Half-Life/Weapons#Crowbar|crowbar]].

===Zombie===
[[File:HLbs_zombie.png|125px|left]]
*'''Health''': 50/50/100
*'''Damage: Single Swing''': 10/20/20
*'''Damage: Double Swing''': 25/40/40

Zombies, or mawmen, are humans that have fallen victim to headcrabs (see above). The infestation has mutated their hands into long, sharp claws, and there is a giant gaping hole in their torsos. MZombies are usually found standing around or feeding on corpses, but are sometimes found on the floor, feigning death until they are shot or someone approaches. They only have one form of melee attack and no form of long distance attack. Zombies are rather slow and can easily be taken out with a [[Half-Life/Weapons#Crowbar|crowbar]] if you step back after each few crowbar swings to avoid the zombie's pathetically slow claw swipes. Alternatively, you can use the [[Half-Life/Weapons#9mm Pistol|pistol]] at long range or if you need to take them out quickly.

===Alien Slave===
[[File:HLbs_islave.png|125px|left]]
*'''Health''': 30/30/60
*'''Damage: Side Swipe''': 8/10/10
*'''Damage: Overhead Swipe''': 25/25/25
*'''Damage: Electricity''': 10/10/15

Alien Slaves, also referred to as vortigaunts, are slaves from the alien planet Xen ordered by their master (whoever that may be) to kill anything that isn't from Xen, specifically humans. At long range, they attack by an electrical charge. When met at close range, they attack with their claws, causing a more damage than their electric bolt. You will know when a vortigaunt is about to attack because they will charge up their bolt for a couple of seconds, emitting green electricity into the air. When this happens, it is best to find cover because, even if you are moving, a vortigaunt's electric attack hardly ever misses a target in its range. Vortigaunts are best taken on with the [[Half-Life/Weapons#Assault Shotgun|shotgun]] at close range or with the [[Half-Life/Weapons#9mm Pistol|pistol]] at longer ranges.

===Houndeye===
[[File:HLbs_houndeye.png|125px|left]]
*'''Health''': 20/20/30
*'''Damage: Wave Attack''': 10/15/15

Houndeyes are small, yellow and green striped dog-like creatures that balance on three legs. When one is in range of a target, it will charge up an attack, making a distinctive whine before unleashing a wave of energy. A houndeye's attack isn't terribly damaging, especially for the amount of time it takes to prepare, but when several attack at the same time, the waves enhance each other, creating a stronger, more damaging wave of energy. When facing a pack of Houndeyes, the best strategy is to find a bottleneck or corner where they must come at you one at a time. Recommended weapons for dealing with Houndeyes are the [[Half-Life/Weapons#Crowbar|crowbar]] if there is only one or two of them, and the [[Half-Life/Weapons#Assault Shotgun|shotgun]] or [[Half-Life/Weapons#9mm Pistol|pistol]] when dealing with a pack.

===Bullsquid===
[[File:HLbs_bullsquid.png|125px|left]]
*'''Health''': 40/40/120
*'''Damage: Acid Spit''': 10/15/15
*'''Damage: Tail Whip''': 25/35/35
*'''Damage: Head Butt''': 15/25/25

Bullsquid are violent Xen creatures that are hostile to many creatures, including other bullsquid. At long range, it will spit acid with decent accuracy, but slow enough that it can be easily avoided. At close range, it is more dangerous, attacking by either slashing you with its tail or knocking you across the room. If there are other enemies around, like [[#Headcrab|headcrabs]] or [[#Human Grunt|marines]], they will often attack these enemies before attacking you. You can use this to your advantage to inflict damage to it while it is not focused on you. At long ranges, a bullsquid doesn't present much of a threat as long as you dodge its slow moving projectile spit, so the [[Half-Life/Weapons#9mm Pistol|pistol]] should be all that is required. At close range, however, the bullsquid is much more dangerous, and may require a few shots from the [[Half-Life/Weapons#Assault Shotgun|shotgun]] or [[Half-Life/Weapons#Colt Python .357 Magnum|magnum]].

==Mid-game Enemies==

===Human Grunt===
[[File:HLbs_grunt.png|125px|left]]
*'''Health''': 50/50/80
*'''Damage: Shotgun''': 3/5/6
*'''Damage: Assault Rifle''': 3/4/5
*'''Damage: Kick''': 5/10/10

Human Grunts, also referred to as "grunts", "marines", or simply "the military", the are a special military task force dispatched by the U.S. Government to contain the incident at Black Mesa by killing everything, including the facility personnel. Grunts are the most common human enemy, and utilize a variety of weapons, vehicles and tactics against you. Grunts are usually armed with an [[Half-Life/Weapons#Assault Rifle|assault rifle]] and [[Half-Life/Weapons#Grenade|hand grenades]], but it is not uncommon to run into one with a [[Half-Life/Weapons#Assault Shotgun|shotgun]]. Human grunts aren't the strongest enemy, but they are crafty and use cover and tactics well. The weapon of choice depends mostly on the situation. At long distance, it is best to use the [[Half-Life/Weapons#Colt Python .357 Magnum|magnum]] or [[Half-Life/Weapons#Crossbow|crossbow]]. At medium range, the all-around [[Half-Life/Weapons#Assault Rifle|assault rifle]] is most likely the best weapon. You could also make one chase you around the corner, then equip the [[Half-Life/Weapons#Assault Shotgun|shotgun]] for when he rounds the corner.

===Hagworm===
*'''Health''': 2/2/2
*'''Damage: Bite''': 2/2/2

Hagworms are small swimming worms, similar in appearance to a leech, that appear in several different underwater parts of the game. They don't do much damage, but they can get in your way as you try to swim and, in numbers, their bites can add up. To solve this, it is usually wise to wildly swing the [[Half-Life/Weapons#Crowbar|crowbar]] as you swim through hagworm-infested waters.

===Ichthyosaur===
*'''Health''': 200/200/400
*'''Damage: Bite''': 20/35/50

Ichthyosaurs are giant fish with powerful jaws that will spin you around and disorient you if they get you. To make things worse, if you happen to fall in the water with an ichthyosaur the only weapons you can use on it are ones that work underwater. These weapons are the [[Half-Life/Weapons#Crowbar|crowbar]] (not recommended), the [[Half-Life/Weapons#9mm Pistol|pistol]], the [[Half-Life/Weapons#Crossbow|crossbow]], and [[Half-Life/Weapons#Grenade|grenades]]. Sometimes it will break the surface and be visible from land, but unless you're fast, you won't have much time to damage it this way. The best strategy for dealing with an Ichthyosaur is to swim backwards firing crossbow bolts at it, though it is good to have an exit strategy in reserve if it gets too close.

===Assassins===
*'''Health''': 30/50/50
*'''Damage''': 8/10/10

Commonly known as "Black Ops", assassins are elite female operatives skillful in stealth and close combat. They utilize silenced pistols, grenades and a variety of martial arts kicks and jabs at close range. They have been confirmed to work independently of the military and have their own objectives to complete, one of which is eliminating you. Assassins are extremely fast and agile and can leap considerable distances, making them very hard to target. Often the only valid tactic is to back into a corner so they can only come at you from one or two directions. If you have any, [[Half-Life/Weapons#Snark|snarks]] are extremely effective against assassins, even if they don't kill them outright. When an assassin encounters snarks they will usually ignore you to fire wildly at the creatures, giving you a clear shot. Otherwise, a quick and powerful weapon, like the [[Half-Life/Weapons#Colt Python .357 Magnum|magnum]], should be used.

==Late-Game Enemies==

===Alien Grunt===
[[File:HLBS alien grunt.png|125px|left]]
*'''Health''': 60/90/120
*'''Damage: Hornets''': 4/5/8
*'''Damage: Punch''': 10/20/20

Alien Grunts are formidable alien foes covered in armor and equipped with a [[Half-Life/Weapons#Hivehand|hivehand]]. Shooting an alien grunt in the shoulders, back, or back of the head will do little to no damage. Your best chance is a stream of bullets to the gut. It is hard to avoid their attacks completely, even behind cover, because the hivehand fires homing hornets. If you can, engage alien grunts from a distance with a heavy hitting weapon, such as the [[Half-Life/Weapons#Colt Python .357 Magnum|magnum]] or [[Half-Life/Weapons#Crossbow|crossbow]], or with a stream of bullets from the [[Half-Life/Weapons#Assault Rifle|assault rifle]].

===Xen Master===
[[File:HLbs_controller.png|125px|left]]
*'''Health''': 60/60/100
*'''Damage: Energy Ball''': 15/25/35

Xen Masters are flying alien creatures that shoot streams of energy balls at you. They are very agile and have a lot of health, so small or slow weapons should be avoided when fighting Xen Masters. On the bright side, they aren't very accurate if you are continually moving or use cover. If there's only one, the [[Half-Life/Weapons#Hivehand|hivehand]] is a good choice because the xen master's attacks are fairly easy to avoid and the hornets home in on their target. If there are swarms of xen masters, it is probably better to use the [[Half-Life/Weapons#Colt Python .357 Magnum|magnum]].

==Heavy Duty Enemies==

===Apache Helicopter===
*'''Health''': 150/200/250
*'''Damage: Machine Gun''': 8/10/10 (It fires 10 rounds per second)
*'''Damage: Missile''': 150/150/150

The Apache attack helicopter makes appearances during some parts of levels that occur on the surface. They can best be taken down by the [[Half-Life/Weapons#Rocket Propelled Grenade Launcher (RPG)|RPG]] or the [[Half-Life/Weapons#Tau Cannon|Tau Cannon]]; other weapons will work but only after a lot of well-aimed shots at the rotors or engines (watch for small puffs or thick trails of black smoke when you score a weak or strong hit). Apaches are equipped with machine guns and, in some cases, air to surface missiles. The weak spots of the Apache attack helicopter are the cockpit and the engine.

===Gargantua===
*'''Health''': 800/800/1000
*'''Damage: Punch''': 10/30/30
*'''Damage: Flame''': 25 at first, but increases the longer you stay in it
*'''Damage: Stomp''': 50/100/100

The Gargantua is a large blue armored creature that appears several times in the game. Each time, it requires an unorthodox method to kill. Although it is possible to kill a gargantua with conventional weapons, it is usually a waste of ammunition. It attacks by slashing you or shooting jets of flame from its hands at close range and by stomping, causing a shockwave of red energy to fly at you at long range. Gargantuas can run as fast as you can and are ruthless enemies. There are four different ones in the game, two of which must be killed and two of which you are better off sneaking past. If you have caught the attention of a Gargantua, many times it is best to enter a small opening where it cannot reach you until it has lost interest in you. 

===Gonarch===
*'''Health''': 2100/3150/4200
*'''Damage: Kick''': 50/60/70
*'''Damage: Acid''': 100/120/160

The Gonarch is a four legged creature with a large egg sack that hangs down below where its legs meet. As the second to last boss, Gonarch can only be found once during the game and it takes a large amount of damage to kill. The sack is Gonarch's weak point, and it can only be harmed when Gonarch isn't progressing farther into its lair between battles. The Gonarch can attack in a variety of different ways. It will release small baby gonarches to attack or fire acid in your general direction when you're at a distance. If you're out in the open, it will run up to you and kick you, knocking you back and giving you a great deal of damage. 

===Nihilanth===
The boss of the game.
