Astral Chain
is a 2019 action-adventure game developed by PlatinumGames and published by Nintendo for the Nintendo Switch. It was directed by Takahisa Taura, who was previously lead game designer for Nier: Automata, under supervision by Devil May Cry and Bayonetta series creator Hideki Kamiya, and character designs from manga artist Masakazu Katsura.
Set in a dystopian future Earth, the game follows the events of a special police task force that protect remnants of humanity from interdimensional creatures and aberrations that invade the planet, with the story centering on the task force's two new twin recruits. Utilizing the titular Astral Chain, the twins restrain and tether the creatures, employing them in combat and investigation, referring to them as Legions. The setting of the game draws heavy inspiration from various cyberpunk manga and anime, while the gameplay combines hack and slash combat with role-playing elements and investigative open-world adventure game sections. The gameplay segments revolve heavily around the simultaneous controlling of two characters; the player character twin and their Legion.
Astral Chain was estimated to have had a five-year long development cycle and follows a slate of previous collaborations between PlatinumGames and Nintendo, with both companies having previously worked together on titles such as The Wonderful 101 and Bayonetta 2. The game was announced February 2019 as a part of that month's Nintendo Direct presentation. Astral Chain received highly positive reviews from critics who praised its dual-character gameplay, world building, presentation, customization, and soundtrack, though it received some criticism for its usage of a silent protagonist. As of December 2022, the game has sold over 1.3 million copies worldwide.
Gameplay
Astral Chain is an action-adventure game where the player assumes the role of a detective from the Neuron special task force, who are tasked with solving cases and investigating incidents that take place on the Ark, the game's environment. Exploring the world, questioning non-playable characters, and examining evidence yields clues and logic puzzles that become leads which further the investigation process. During the course of the game, the player will access the Astral Plane, an interdimensional area where they must traverse hazardous terrain, solve puzzles, and battle enemies, similar to that of traditional video game dungeons.The player is able to summon a tethered familiar known as a Legion, bound by a chain that is the game's namesake. Legions come in various different forms sporting different abilities that are used both for puzzle-solving and combat. These include: a sword-based Legion with swift blade attacks that can be used to sever circuitry and interrupt enemy attacks, an archer Legion that can target weak points and distant switches, a Legion with powerful punches that can move large objects, an axe-based Legion which generates a shield and can destroy breakable objects and enemy shields, and a K9 Legion that can track scents, unearth hidden objects, and also be ridden for added mobility and evasiveness. The player begins the game with the Sword Legion, capturing the other four over the course of the game. Legions can be swapped at any time during battle, and can also be upgraded via experience points and unlockable skills. On top of the player's own health, Legions have their own individual health meter that gradually depletes while they are summoned, and they are also susceptible to enemy attacks, which depletes higher amounts of their health. Their health regenerates automatically when they're not active. If the entirety of a Legion's health is depleted, the player becomes unable to utilize it until it has restored all of its health.
Combat takes place in real-time, both melee and ranged weapons are used to fight enemies, primarily malevolent creatures called chimeras. Similar to the combat dynamics of Capcom's Chaos Legion, the player can summon the Legion during combat in order to have them automatically fight with the player to create combo attacks. The Legion can be manually directed with the right analog stick, allowing the player to position the Legion for more specific maneuvers. Each Legion also has a unique action that allows the player to take direct control over a Legion's signature ability, such as manually aiming and firing projectiles with the Arrow Legion, or using the Arm Legion as protective armor that can hover over hazardous terrain and attack with a flurry of punches. Additional skills include being able to perform powerful health-restorative finishing moves, unchaining a Legion to summon multiple at once, using the Astral Chain that connects the player to the Legion to bind enemies or as an arresting wire on enemies that attempt charging into the player. The player is also able to utilize the chain in order to zip line out of danger through enemy crowds, as well as crossing gaps and bottomless pits between buildings and platforms.
Completing combos, interrupting enemy attacks, restraining enemies, dodging, and deploying a Legion at the correct moment will offer the player a chance to perform a sync attack, requiring the player to press the left trigger at the right instant, similar to a quick time event. Sync attacks can extend combos, trigger special attacks, bind enemies, and help the player recover from a fall. After performing a large number of sync attacks, the player may fuse with their Legion for a short while to recover health and deal large amounts of damage.
The game features four difficulty settings, allowing the player to switch difficulty between each chapter. The highest difficulty is only unlocked for a corresponding chapter once the player has beaten it once. When played on the two highest difficulties, the game ranks the player based on their individual case performance, giving the player an overall ranking at the end of each chapter. On the two lowest difficulties, the player will not be ranked.
Early in the game players unlock the IRIS tool, a heads up display from which they can inspect the environment and search for clues, as well as save their progress, manage the inventory, customize in-game menus, view the level map, and manage orders. Previously completed chapters can be accessed and replayed via the player's desk at the Neuron Headquarters at the beginning of each new chapter. The player can also return to this area to maintain and customize their Legions, customize their character, and interact with other Neuron officers. Consumable items can also be obtained from vendors that can later be used for crafting, health recovery, or combat.
Plot
Setting and characters
Astral Chain is set in the year 2078, where humanity is on the brink of extinction. The remnants of the human populace have retreated to a megacity, a massive artificial island called the Ark. The world is under attack by lifeforms called chimeras, which are normally invisible, and reside in the Astral Plane, an alternate dimension composed of crystallized data that is uninhabitable to humans. The chimeras cause destruction, drag civilians into the Astral Plane via wormholes called gates, and spread "red matter" that "redshifts" living things, corrupting humans into aberrations. To combat the chimeras and the Astral Plane, the Neuron task force, a division of the Ark's police, is employed. They utilize Legions—subservient chimeras that have been tethered to an officer via a psychic chain—in order to assist with combat and investigation.The player assumes the role of one of two twin police officers, who join Neuron early into the game as new recruits. The player-selected character, the "Legionis", has a custom first name and identity, whereas their opposite-gender twin is given the name Akira Howard. The two were born to a redshifting woman in the midst of the Pandemic, an outbreak of corruption in Zone 09 of the Ark. After their birth and their mother's death, they were adopted by Maximilian Howard, the captain of Neuron. Other characters include Neuron commander and scientific genius Yoseph Calvert, chief medical officer and scientist Brenda Moreno, veteran officers Alicia Lopez and Jin Wong, who assist the player in the field, Neuron dispatcher and former TV newscaster Olive Espinosa, and Neuron office manager Marie Wentz. The Neuron officers are also assisted by a hacker named Harold "Hal" Clark, who pilots a modified field drone.
Story
The Legionis and Akira are dispatched to respond to an aberration attack, but are quickly outmatched by chimeras. The twins are saved by Neuron officers Max, Alicia, and Jin, who wield Legions capable of fighting them. Yoseph assigns Legions to the Legionis and Akira, enabling them to repel the chimeras. Afterwards, the twins are formally inducted into Neuron. Their first investigation mission goes awry when the Legionis ends up being pulled into the Astral Plane, causing the rest of the squad to pursue them in through the gate to save them. As prolonged time in the Astral Plane redshifts humans, the Neuron officers grow weak and lose control over their Legions, causing them to break free and go berserk. In the end, only the Legionis is successful in subduing their Legion, gaining a new level of control over it. Max battles the remaining frenzied Legions and sacrifices himself to allow the rest of the squad to escape. Meanwhile, the Legion production facility at the Aegis Research Institute, a facility responsible for treating redshift and researching the Astral Plane, is attacked and put out of commission. This leaves the Legionis as the only officer with access to a Legion.The Legionis is sent on further missions to respond to chimera attacks, eventually recapturing the lost Legions in the process. During this time, the twins come into contact with Dr. Jena Anderson, a former pupil of Yoseph's who is instigating chimera attacks and bears a grudge against the UNION, the Ark's ruling government. Akira is critically wounded, saving the Legionis from an attack meant for them, and Jena evades capture. After visiting a comatose but recovering Akira at the ARI, the Legionis finds out from Jena that the circumstances of their birth during the Pandemic nearly twenty years before are the reason why they have such control over their Legion. She then leads them to investigate Zone 09, a zone that most are forbidden from entering or exiting, quarantined after the Pandemic. The Legionis goes undercover and explores Zone 09 with Hal, discovering that UNION developed a drug called Blue Evolve that could allow humans to fight chimeras, which carried the side effect of turning the users into aberrations, causing the Pandemic. After battling one of Jena's chimeric homunculi, they are saved by a recovered Akira, clad in black armor and fighting with a new Legion, their control over it now on par with the Legionis' abilities. Due to entering Zone 09 without permission, the Legionis is jailed for insubordination, and Hal goes into hiding to avoid arrest.
After another wave of chimera attacks occur, Neuron is forced to provisionally release the Legionis to combat them. Jena stages a large scale invasion of the Ark, announcing her intention to save humanity by merging Earth with the Astral Plane, which serves as a collective memory bank of humanity. The skirmish leaves Neuron's headquarters defenseless, allowing Jena to infiltrate it and take Yoseph hostage. The twins arrive to rescue Yoseph, causing Jena to power herself up with Blue Evolve before battling the Legionis. During the battle, the Legionis is fatally wounded and dies. This causes their Legion to merge with them to resurrect them, but the resultant fusion goes berserk, attacking Akira. Jena distracts the transformed Legionis and sacrifices herself in the process, warning them that this is the true form of their Legion's power. Yoseph then calls in the Ravens—a newly created task force of Legion users—and orders them to kill the Legionis, causing them to fall off an overpass.
The Legionis wakes up back in human form, having been rescued by Hal and Olive, and brought into a hiding place in Zone 09. Hal explains that Yoseph has largely replaced Neuron with the Ravens and is actively hunting the Legionis, accusing them of treason. While carrying out a covert rescue operation to rescue Brenda, also a fugitive, from the Ravens, the crew is confronted by Akira, who tries to convince the Legionis to return to Neuron. However, they are ambushed by the Ravens, who reveal themselves to be clones of Akira, who they quickly kill at Yoseph's command. As with the Legionis, Akira is saved from death by their Legion, and their own fusion goes on a rampage. To stop Akira, the Legionis willingly merges with their own Legion and—now in control of their fusion—manages to beat them back into human form.
Wanting to find out and stop Yoseph's plans, the twins stage an assault on the ARI. Suffering a mental breakdown after finding multitudes of more clones there, Akira leaves the Legionis behind. When they catch up, they fight to a stalemate, after which Yoseph appears. He uses the clones as a catalyst to create the ultimate Legion, Noah, and merges himself with it, intending to absorb all remaining life on Earth in order to become a god. Akira, protecting the Legionis, is absorbed into Noah alongside the clones. The Legionis battles Noah, weakening him enough to allow Akira to seize control of Noah's body, which allows the Legionis to destroy Noah at the cost of Akira's life.
Following Noah's destruction, chimera attacks begin to decrease drastically, allowing humans to consider leaving the Ark and reclaiming the rest of Earth. Alicia and Jin put Neuron back together, with Olive as interim commander, and the task force continues to handle the few chimera attacks that still occur on the Ark. A remaining Akira clone is given the original Akira's memories by Brenda using traces found in their Legion, effectively resurrecting them, and the Legionis resolves to keep fighting by their side.
