"Well, Gordon, I see your HEV Suit still fits you like a glove. At least the glove parts do."
Isaac Kleiner[src]
 

The HEV Suit,[1] or Hazardous EnVironment suit, often called the "Hazard Suit" for the sake of convenience, is a full-body hazardous materials suit developed at the Black Mesa Research Facility. Designed for Black Mesa scientists to protect them from radiation, energy discharges, blunt-force trauma during the handling of hazardous materials, and the effects of traveling to Xen as part of Survey Teams.

It is predominantly worn by Gordon Freeman during much of the Half-Life series - first as the Mark IV suit in Half-Life, then as the upgraded Mark V suit in Half-Life 2. It allows him to sustain many injuries that would normally fatally wound him.

The HEV Suit is related to both the Powered Combat Vest (PCV) used by the Hazardous Environment Combat Unit (HECU), and the armored vest and helmet used by the Black Mesa Security Force.

Mark IVEdit

The HEV Mark IV suit worn by Gordon Freeman in Half-Life has a built-in flashlight, Geiger counter, morphine administrator (which allows Gordon to function normally even after serious injury), an optional Long Jump Module which allows jumps over large distances (greatly increased horizontal range; vertical distance is elevated only slightly), a radio, tracking devices, and a heads-up display (HUD) which tracks health status and weapon ammunition usage, as well as including a weapons management system.

The suit contains an on-board computer system that constantly monitors the user's health and vital signs, reacting to any changes in the user's condition with activations in the aforementioned apparatus, and a soothing female-computer voice.

Additionally, the suit has an electrically hardened armor/energy shield system that can be charged at HEV chargers throughout Black Mesa. While charged, the suit provides greater protection from injury as the charge absorbs more than two-thirds of any damage or trauma experienced by the wearer, with the exception of fall damage, which is absorbed directly into body-integrity, and oxygen deprivation, caused by swimming without surfacing for long periods of time. With a fully charged suit, Freeman can survive several dozen bullets of small arms fire, continuous fire or even a direct hit from a rocket propelled grenade (but suffering about sixty percent damage).

The suit also features an optional helmet, as seen on various HEV-enclosed corpses dotted around Xen, mainly at the ruined research camp seen in Blue Shift. Although, when Freeman is spotted through Opposing Force, he enters Xen through the portal without wearing a helmet, such being the situation he would need it the most. Headcrabs will never attempt to attach directly to Freeman's head either (although, in the official Half-Life manual, Freeman never allows a headcrab to attempt to).

The HEV Suit is not exclusive to Freeman. Many can be seen worn by slain Black Mesa research members on Xen. Two additional (empty) HEV storage units are seen near the start of the game in Sector C, which are used by the main protagonists of Decay, Gina Cross and Colette Green and three empty HEV storage units can be seen near the end of Lambda Core.

The suits also come in different colors. Although many, including Gordon's and the ones belonging to the corpses seen on Xen, are orange, Gina wears a beige suit, while Colette wears a maroon suit.

Freeman dons the suit at the beginning of Half-Life, and is allowed to keep it at the end of the game by the G-Man.

Mark VEdit

In Half-Life 2, despite being allowed to keep it in the previous game, Freeman starts without the suit. After a visit to Dr. Isaac Kleiner, his former colleague from Black Mesa, Freeman receives an upgraded HEV suit, the Mark V.

Dr. Kleiner, as well as other characters occasionally refer to this suit as Gordon's "old suit," indicating that it is upgraded from his old Mark IV suit; it isn't explained how Dr. Kleiner acquired it as Gordon was placed in stasis wearing it. However, the G-Man releases Gordon wearing "civvies" (presumably the blue denim 'prison' uniform) in Half-Life 2, so it is likely that he 'arranged' it somehow.

New features include a visual zooming capability, limited enhanced running (sprint) capability, an injector to administer antidote for neurotoxins such as Poison Headcrab venom, an optional ammo and health counter on the crosshair (enabled by the player in the game's "Mouse" options), and the capability to use Combine power nodes to charge the suit. This design feature would have an unexpected effect later on in the game, when the suit appears to be infused with "Dark Energy" from a Combine weapon confiscation field, allowing the suit to store twice as much energy as normal, with maximum power at 200 power units, and will heal Gordon's health back to 100%. At this point, the suit also charges much faster and efficiently, capable of going from 0 to 200, without even depleting a single charger to half capacity (normally, a charger can only give the suit 75 power units).

Unlike the Mark IV, the Mark V uses only one auxiliary power source for the flashlight, enhanced running and oxygen supply (though, as of the events of Episode 2, the flashlight now has a separate charge meter). In addition, the Long Jump Module is no longer an available upgrade found in the environment.

Gina Cross is said to have tested a Mark V prototype under the supervision of Richard Keller before the Black Mesa Incident,[2] but it is unknown how this is related, if at all, to the Mark V suit featured in Half-Life 2.

Detailed analysisEdit

In Black Mesa's Lambda Complex there were stored suits used by various members of the Xen survey teams.

It should be noted that HEV energy chargers in Half-Life have the trademark (TM) symbol added after the HEV letters, which suggests that the chargers, HEV suit, or both, are produced by a non-government company. An Easter egg in Half-Life 2, however, reveals an old cover of an HEV charger lacking the trademark logo.[3] However, this could be worn off like most of the HEV lettering on the faceplate.

The HEV suit is unusual compared to conventional hazard suits like Hazmat, specifically that it was designed with combat in mind (where the environment actively fights back against trespassers) as the suit possesses the ability to track weapons in hand, along with their ammunition. The suit also possesses the ability to store multiple weapons and tools, though the method by which this is accomplished is unknown.

These combat-oriented features are explained by the visits many Black Mesa personnel made to the border world of Xen which contains many dangerous and hostile forms of life.

It is notable that the Powered Combat Vest worn by the player in Opposing Force apparently uses similar technology as it is also able to replenish its power from Black Mesa HEV chargers. It is unclear which technology was invented first, though it would be reasonable to assume that, since the PCV lacked a "mark" designation, the HEV suit was developed first and the design specifications sold to the government.

The symbol on Gordon's HEV suit is the lower case Greek letter Lambda, λ. This symbol is used by scientists to denote the decay constant of radioactive elements (related to the half-life of an element). As well as appearing on Gordon's suit, the symbol replaces the letter "a" in the game title, Hλlf-Life, and is the name of the complex in the Black Mesa Research Facility where teleportation experiments are conducted. The Lambda symbol is also seen in Half-Life 2 as a marking of the human resistance, seen close to hidden supplies and on the arm bands of better equipped resistance fighters.

HEV Suit voiceEdit

Kathy Levin recorded the HEV Suit information and warnings. They were recorded only once for Half-Life and reused in the subsequent games featuring it.

  • In a Half-Life new game, when the player obtains the HEV suit for the first time, the HEV suit voice will say 9 statements:
    • Welcome to the H.E.V. mark IV protective system, for use in hazardous environment conditions.
    • High impact reactive armour activated
    • Atmospheric contaminant sensors activated
    • Vital sign monitoring activated
    • Automatic medical systems engaged
    • Defensive weapon selection system activated
    • Ammunition level monitoring activated
    • Communications interface online
    • Have a very safe day!
  • When the player obtains a battery, the HEV suit will say:
    • Power # percent. (# standing for the suit power after picking up the battery, rounded down to the nearest multiple of five.)
      • When the player gets 100% power, the HEV suit says the above line with a higher, "happier" sounding voice, and it says "Power level is one hundred percent" instead of shorter "Power one hundred percent."
      • The above only happen if the power is achieved with batteries; if the power is filled up with a charger, the suit will not say anything.
  • When the player has dropped from a fairly high place, and the health loss resulting from the fall reaches 26 or above, the HEV suit voice will say:
    • Major fracture detected
    • Automatic medical system engaged
    • Morphine administered
  • When the player also has dropped from a low place, and the health loss resulting from the fall reaches than 100, at the next round, the HEV suit voice will also say:
    • Minor fracture detected
  • When the player has receives damage from a snark bite attack, zombie claw swipe or double slash attack, or Xen creature bite, hook, teeth, claw attack or Gargantua punch attack the HEV suit voice will say:
    • Minor lacerations detected
  • When the player also has receives damage from a barnacle crush bite attack, tentacle beak attack or gonarch front legs attack, the HEV suit voice will also say:
    • Major lacerations detected
  • When the player health reaches 25 or below:
    • Vital signs critical
    • Seek medical attention
  • When the player health reaches 9 or below:
    • Emergency! User death imminent
    • Seek medical attention
  • When the player's gun runs out of ammo:
    • Ammunition depleted
  • When the player obtains a Long-Jump Module, the HEV suit voice will say:
    • Power-assisted movement activated
  • When the player is exposed to radiation, the HEV suit will say:
    • Warning! Hazardous radiation levels detected!
  • If the player is damaged by heat, the HEV suit will say:
    • Warning! Extreme heat damage detected!
  • If the player is damaged by electrical short, the HEV suit will say:
    • Warning! Electrical damage detected!
  • If the player is exposed to chemical waste, the HEV suit will briefly say:
    • Warning! Hazardous chemical detected!
  • If the player is exposed to paralyze, the HEV suit will say:
    • Warning! Blood-toxin levels detected!
  • If the player is exposed to nerve gas, the HEV suit will also say:
    • Warning! Biohazard detected!
  • When the player gets deep by underwater, and then exposed to oxygen levels or health reaches 75 or below, the HEV suit will also briefly say:
    • Vital signs are dropping
  • If the player is damaged by the Gargantua stomp attack, or the Houndeye sonic attack, the HEV suit will say:
    • Internal bleeding detected!
  • If the player is shot by any enemies with guns (i.e., HECU, Black Ops Assassins, Combine Metro Police and Combine soldiers), the HEV suit will say:
    • Blood loss detected!
  • If the player is poisoned by a Poison Headcrab.
    • Warning! Blood-toxin levels detected!
    • Antidote administered!

Behind the scenes Edit

  • Many sounds were recorded for the HEV suit but were never used, mostly of a medical nature; for instance, "local tourniquet applied". These sounds are included in the files but were presumably cut due to the lack of an actual purpose within the game, since the HEV suit is mostly aesthetic. Some unused files seemed to have been for either weapon pickup or weapon selection, as there are files such as "get_shotgun.wav."
  • Originally, in Half-Life, the suit power indicator was a battery-like symbol instead of the current number next to a human figure and a vertical bar. The battery sprite remained in Half-Life: Day One.

Trivia Edit

  • In the original Half-Life, the HEV Suit's armor not only absorbed 66% of all damage received, it also reduced the total amount of damage any given attack would inflict on the player (i.e. enemy melee attacks would do a total of 6 damage instead of 10 if the suit had power). This changes in Half-Life 2, where the player receives the same amount of damage whether or not the HEV suit has any armor energy. To compensate, the HEV suit armor is more effective in Half-Life 2, absorbing 80% of all damage received instead of 66%.
  • In the texture of the HEV Suit's back in Half-Life, the word Valve can be faintly seen. This applies only to player models that use HEV Suits, not to the HEV Suit's worldmodel.
