Gameplay
There are three campaigns in the game, one for each race/faction (the Predators, the Aliens and the Colonial Marines), that, while separate in terms of individual plot and gameplay, form one overarching storyline.
Following the storyline of the campaign modes comes the multiplayer aspect of the game. In this Multiplayer section of the game, players face off in various different gametypes in various different ways.
Predators
As in the films, the Predator prefers to stalk its prey from the safety of treetops and the gameplay reflects this, the player leaping from branch to branch automatically with the help of a "focus jumping" game mechanic. The Predator has different vision modes, the most recognizable from the films being a thermal imaging scanner, but the player also has different vision modes for spotting Aliens (only accessible from a special mask the player picks up in-game) and viewing the world normally. For example, the Heat Vision mode allows the player to see marines very clearly, while it renders Aliens nearly invisible; the Alien vision works in reverse, making aliens appear clearly and marines nearly invisible. Regular vision allows one to see the environment and other predators better than the former two visions, making battles between two or all three species a tactical juggle to prioritize enemies based on their threat to the player.
The Predator’s gameplay is more based on stealth and tactics than the average first-person shooter. The player has to be aware of Aliens, which have the ability to see through a Predator's cloaking device, that may climb up a tree and attack from below as well as taking care not to reveal themselves to marines too early as the marines’ weaponry and numbers are more than a match for the Predator. For long-range weaponry, the Predator can use a shoulder-mounted plasma cannon in addition to a glaive-like disc and a combi stick (or throwing spear). For close-range combat, the Predator has four retractable wristblades on its arms.
The wristblades allow for the Predator to perform a "trophy kill, a nod to the movies in which the Predators take trophies, usually skulls, from their defeated enemies to show their prowess in the hunt. OXM labeled the trophy kill mechanic as "spectacularly violent" and it has been partially censored to avoid an Adults Only rating in the United States as it was "several measures more graphic" than any other recent games. There are several animations, one of which is, a "terrified" marine dragged into the center of the screen by his or her throat, which the Predator then snaps effortlessly with the accompanying sound of "someone biting into raw celery". The neck broken, the Predator decapitates the marine, a "sizeable portion" of the spinal cord following. Even after this, the marine is still alive for a short period of time, "gasping his last, with nothing but bloodied, glistening vertebra beneath his chin.
Jason Kingsley, the CEO of Rebellion, defended the brutality of the trophy-kill system, stating "This is obviously a game based on adult-rated movies, and we want to make sure it’s very clearly an adult-rated game. It's an issue for me; some computer games are for kids – we're not making a computer game here for anyone other than adults. That's very clear and within that context, I think the violence is part of the character and the world – so we're talking about a fantasy world here and fantasy creatures and we're talking about trying to build up a mythos. I remember the first time I saw it, one of the particular Predator kills, everyone went 'Oooh'. But it's what the Predator does in the movies.
The Predator campaign explains how their species considers the war tactics of the human Marines juvenile. A quote from the intro states: "We are old, my brother. Our race is few and scattered. Our ancestry lost to myth. The humans are still children, creatures of desire and hubris, with no comprehension of the long hunt. Still, they make good sport. They have discovered a trophy long locked away. They must not be allowed to find the crucible that spawned our most respected prey. If they succeed, all life will succumb to the crawling dark...".
Aliens
Aliens fight in close-quarters with their claws and tails, getting as close as possible to their prey as quickly as possible. Aliens have the ability to climb walls and jump from distances without effort, and can blend in with shadows, using darkness to their advantage. Within limited ranges, aliens can seek out prey through walls. These senses also allow Aliens to clearly observe cloaked Predators. In the single player campaign, players will have the opportunity to harvest 'hosts'. By pinning the host, nearby facehuggers are able to locate and latch on to them, thereby propagating the Hive. Throughout the game, the player also has the opportunity to perform 'Stealth Kills'.
Colonial Marines
The Colonial Marine campaign is far closer to that of a standard first-person shooter. Marines carry a wide arsenal including pulse rifles, flamethrowers, and auto-tracking Smartguns. To help navigate the surroundings, marines are equipped with shoulder-mounted lamps, surveying flares to briefly illuminate darkened areas, and motion trackers, capable of providing info on hostile positioning as they move.
Plot
Marine
As a Marine, the game starts out above the planet, with the Marines squads on two separate ships, one of which is identified as the USS Marlow. The Marines have been given orders for a combat drop. When the Predators' ship comes out of cloak and destroys the Marlow, Major Van Zandt directs the surviving shuttle to land. The player Marine, dubbed "Rookie", is knocked out during the drop, and regains consciousness in the heart of the chaos itself. At Corporal Tequila's direction, Rookie is sent to several parts of the wrecked human colony with the purpose of getting systems back online to locate all the surviving Marines, especially Major Van Zandt. However, the Major is discovered cocooned, forcing Rookie to shoot him.
Moving further into the newly established hive within the refinery, Rookie encounters the Alien Queen and sets her on fire, ultimately killing her in an explosion with help from Tequila. Going through the swamp, Rookie is contacted by Tequila, on-board a drop ship to pick him up, but the ship comes under fire from an Predator and crashes before the rescue can be made. The now-stranded Rookie receives the assistance of the colony's administrator, Katya, from the Weyland-Yutani group, that was originally sent to investigate the pyramid. Following Katya's instruction, Rookie is able to locate other survivors throughout the ruins and fight and kill a Predator before finally rescuing Tequila. Tequila asks the Rookie to shoot her but Katya informs him that if Rookie could get Tequila to the research lab, Katya could perform surgery on Tequila to extract the alien inside her. Weyland finds out about this during the procedure and cuts the power to prevent Katya from trying to remove the alien from Tequila. Rookie is forced to put her into a stasis capsule to prevent the alien from "bursting" and killing her.
With their dropship and the Marlow destroyed, Rookie is informed by Katya, after finding out that she was an android, that Weyland has a datapad that can contact his personal dropship and get them off the planet. Rookie goes below the facility to confront Weyland, in order to acquire his datapad, and uses it to recall Weyland's dropship, getting himself, Tequila, and Katya off the planet and in the process revealing the Weyland who was on the planet was an android the entire time. Rookie, Tequila, and Katya are then seen in cryo-sleep on-board the dropship, which is traveling to Weyland's personal cruiser, which is in orbit around the planet, while the pilot uploads the datapad's contents to the cruiser's computer. An older-looking Weyland is then delighted to learn that Tequila's chestburster is secure, and to receive the vital contents of the datapad: the coordinates to the Xenomorph homeworld.
Alien
As an Alien, the game begins in a laboratory, where two humans are being kept imprisoned. As one of them wakes up, a chestburster emerges from the other, killing him. Soon after, a chestbuster breaks through his body, killing him as well. As scientists enter the room to collect the specimens, they find that "Specimen 6" is missing. A Chestburster then emerges from the second victim's mouth, rather than the containment tube, and as a result the room is gassed by head scientist Doctor Groves, killing the two scientists. However, Weyland prevents the death of the creature, impressed with the chestburster's cunning, and tells Groves to assign the creature to a special program.
Days later, once "Specimen 6" is fully grown. During an observation of its abilities, it is told by its Queen, which is also imprisoned, to escape, but it is gassed and recaptured. As Weyland opens the door to ancient ruins built by the Predators' ancestors, the structure emits an electro-magnetic pulse that disables the local human colony's systems, also disabiling Specimen 6's restraints, allowing it to escape. Specimen 6 releases the other captive Aliens and the Queen. Once free, the Aliens retreat to the colony and the nearby refinery, where they begin to multiply through Facehuggers. The Queen establishes a hive in the refinery and the Aliens become dormant, until the arrival of the Colonial Marines.
After the Marines arrive, Specimen 6 begins to kill Marines and disable the colony's systems. While on its mission, it eventually finds itself at the ruins Weyland opened, where it and other Aliens encounter a duo of Predators, which they immediately battle and kill. An Elite Predator appears and battles Specimen 6, who weakens it to the point that a Facehugger is able to attach itself to it. As Specimen 6 returns to the Hive through the jungle, it stops and is mentally stunned as it sees the refinery is on fire, and senses that the Queen is trapped in the fire, set by the Marine "Rookie" (as seen in the Marine Campaign), and died in an explosion. As it goes into shock, Weyland and a few combat androids discover Specimen 6, and at Weyland's request, they capture it. They take the captured Specimen 6 off-world to an orbiting ship, where Six kills the crew. It is shown that Specimen 6 escaped and began to build a hive in the ventilation system. It is then shown that Specimen 6 has metamorphosed into a new Queen, dubbed "Queen 6".
Predator
As a Predator, the game starts in the jungles, where a youngblood is proving himself strong and fit enough for the rank of Elite. Once the trials are complete, the Elite, named "Dark", is dispatched with a group of other Predators to a planet to investigate a distress call, sent by a youngblood hunting party on another planet (BG 386). On arriving at BG 386, the Predators destroy the orbiting Marine ship, the USS Marlow, and launch the Elites to the planet's surface.
On the planet, Dark finds one of the dead Youngbloods, and sets its wrist bracer to self destruct in order to keep the humans from discovering their technology. Dark is then told to make trophies of the Marines ,on account of their intrusion on the planet ,and therefore, sacred hunting grounds for Xenomorphs, or Aliens. He goes on to infiltrate the Colonial Marines' forward base in the colony, disabling the systems and releasing the Xenomorphs into the open. Dark infiltrates the Refinery, and finds the Alien Queen already killed by Rookie, the Marine from the Marine campaign. He enters the ruins after escaping the refinery and finds the mask of an ancient and legendary Predator. Replacing his own with this mask, Dark gains the ability to see and target Aliens in the dark as well as holes and crevices from where they can hide. The mask plays back holographic scenes from many years back celebrating the Predators' first victory over the Aliens. It is at this point the player is instructed to find a certain artifact of high importance to the Predators - an ancient wrist bracer.
Venturing through the ruins, Dark finds stranded Colonial Marines and more Aliens. Reaching an ancient combat arena, the Elite battles a Praetorian. When the Praetorian is defeated, Dark acquires an ancient combi-stick, a spear-like weapon that can be thrown while maintaining the thrower's cloaking.
The Elite then infiltrates the research lab Weyland-Yutani built above the Predators pyramid and searches for the wrist bracer stolen by the colonists for research. Dark has his first encounter with corporate combat androids. Weyland attempts to capture the Elite for live experimentation, but fails. The Elite successfully acquires the wrist bracer, and after battling through the Xenomorph labs and the Queen's former chamber and makes it to the pyramid killing the Predalien. He is then informed the wrist bracer is to be used to wipe out the entire temple and the colony around it, as the temple's sanctity had been violated by the humans, and to purge the stain on the Predators' history. After escaping the temple Dark returns to the Predator ship and his ancient mask gives him data revealing the Alien's homeworld.
