The Bio-Mask is one of the main tools used by the Predators. These masks contain a variety of functions which the Predators may require during a hunt. As well as protecting the Predator's head, the mask has a sound amplifier, multiple vision modes, a zoom function, some diagnostic capabilities and a recording system. The mask may also have a red targeting laser, used by a Predator for accurate plasma caster shots. It also might be used as a breathing tool, as seen in Predator 2 when the City predator lost his mask, he had to use a device similar to an inhaler to breathe.
The masks were shown to have access to several different visual frequencies, is most commonly seen being infrared, effective to visualize the humans, but useless in a xenomorph hunt. Also available is a spectrum and a specifically tuned mode, EM field detector, used to visualize Xenomorphs. Additional vision modes are available to determine the health status of the targets. In Alien vs Predator : Requiem one yautja gathers the substance he was containing a Facehugger in and installed a new vision mode on his Bio-mask which allowed him to see the substance highlighted. He did this by inserting the substance via a needle into his Wrist Gauntlet, suggesting a connection between the two.
Housed within the helmet is a targeting and tracking system for shoulder based plasma casters. A shoulder mounted plasma caster uses this laser target designator, which comprises three corners of an open triangle, to aim at the designated prey. Incorporated to finalize the shot is a lock-on system. As the quarry is decided upon, the designator will zoom a triangle in on the prey which will flash and turn solid red, then fires. This also has a zoom capability, so the Predators can see and aim over great distances. This tracking system also allows the Predators to plot trajectories of thrown objects. The targeting system can also be used to heat up metals like wrist blades.
Another feature of the Predator's mask is its voice translator/recorder. This device can both record and play strips of audio, which a Predator may use to express meaning or catch prey off guard, or to simply listen to the voices of their prey, as if to study their language. The mask also seems to affect hearing as well; in Predator, when the Predator took its mask off, it heard things at a much higher pitch than before and slightly more distorted. As seen in Aliens vs. Predator: Requiem, the helmet also has a video playback mode that displays what the wearer has witnessed or been involved in.
In the Aliens versus Predator video games, the Predator has four vision modes, regular vision, thermal, electric, and Predator vision.
However, in AVP3, there are only three Predator vision modes: Normal, Thermal/Heat, and Alien. Normal mode is self-explanatory. Thermal vision is used to detect humans and Synthetics. Alien vision is to detect Xenomorphs. Humans, Synthetics, and Predators are nearly invisible in Alien mode, whereas Xenos are nearly invisible in Heat mode.
In Predator: Concrete Jungle, the Predator's mask offered four types of vision and varying diagnostic functions for each: Normal Vision, which was the same as a human and had no diagnostic; Thermal Vision, which highlighted heat signatures and could analyze health and armour weaknesses in prey. Although in this game it could also highlight Xenomorphs even though in the movies and games they are not seen in Thermal; Tech vision, which contrasted energy sources and analyzed a prey's weapon systems; and Neuro Vision, which exposed the prey's current emotional status and, on scan, would show the target's affiliation and rank.
Predator is a 1987 American science fiction action film directed by John McTiernan, starring Arnold Schwarzenegger, Carl Weathers, Jesse Ventura, and Kevin Peter Hall. It was distributed by 20th Century Fox. The story follows an elite special forces team, led by 'Dutch', on a mission to rescue hostages from guerrilla territory in Central America. Unbeknownst to the group, they are being hunted by a technologically advanced form of extraterrestrial life, the Predator. Predator was scripted by Jim and John Thomas in 1985, under the working title of Hunter. Filming began in April 1986 and creature effects were devised by Stan Winston.
An alien spacecraft enters the Earth's atmosphere and jettisons a pod, which descends onto the planet. Some time later, Major Alan "Dutch" Schaefer arrives in Central America with his elite team for an operation to rescue a presidential cabinet minister and his aide who had been abducted by guerrilla forces. The team consists of Mac Eliot, Blain Cooper, Billy Sole, Jorge "Poncho" Ramirez, and Rick Hawkins. Dutch's old military friend George Dillon, now working for the CIA, accompanies them as a liaison. The team is inserted into the jungle by helicopter and begins its hunt.
They soon find the wreckage of a downed helicopter and later, the remains of Army Special Forces, whose presence in the country mystifies Dutch, while shocking them that the bodies are found to be hanged with their skin removed. They track the guerillas to a heavily defended rebel encampment which they destroy, except for a woman named Anna whom they take prisoner. Dutch is enraged when Dillon confesses the rescue mission had been a ploy to get his group to attack the camp and that the men they found earlier had disappeared in a failed rescue of two CIA agents. As the team make their way to the extraction point, they are observed from afar by an unknown creature using thermal imaging.
Anna briefly escapes, but when Hawkins catches her, he is seized and dragged off. The nearly invisible creature spares the unarmed Anna. Moments later, while the team is looking for Hawkins' killer, Blain is killed. Mac physically sees the creature and opens fire on it, but it disappears into the jungle. Anna offers the team insight on the creature which is something of a local legend. The team sets a trap, but it avoids capture, severely wounding Poncho in the process. Mac and Dillon are killed in the ensuing chase, and Billy is slain making a stand. The Predator catches up to Dutch and engages in a short shootout during which Poncho is killed. Realizing the creature only attacks those possessing weapons, a wounded Dutch sends Anna unarmed to the extraction point. Jumping off a waterfall, he narrowly escapes the creature by inadvertently masking his body's heat signature with mud and witnesses the Predator's true form when its active camouflage fails in the water. Dutch applies more mud, improvises various weaponry and traps, then baits the Predator into coming out by starting a large fire.
Hearing Dutch's war-cry, the Predator arrives to investigate and eventually traps him. Discarding its electronic weaponry, the alien challenges Dutch to hand-to-hand combat. Battered and barely able to move, Dutch manages to drop the counterweight from one of his traps, which falls and crushes the creature. As Dutch asks the mortally wounded alien what it is, the creature mimics his question in garbled English and then activates a self-destruct mechanism on its wrist device while laughing, gradually increasing its laugh into a human-like pitch. Dutch barely escapes the massive explosion and is rescued by helicopter along with Anna.
