is a 1995 role-playing video game developed and published by Square for the Super Nintendo Entertainment System. It is the first installment of the Chrono series. The game's plot follows a group of adventurers who travel through time to prevent a global catastrophe.

The game's development team included three designers that Square dubbed the "Dream Team": Hironobu Sakaguchi, creator of Square's Final Fantasy series; Yuji Horii, creator of Enix's Dragon Quest series; and Akira Toriyama, character designer of Dragon Quest and author of the Dragon Ball manga series. In addition, Takashi Tokita co-directed the game and co-wrote the scenario, Kazuhiko Aoki produced the game, while Masato Kato wrote most of the story.

Chrono Trigger was a critical and commercial success upon release, receiving multiple accolades from gaming publications, and is considered one of fourth-generation console gaming's most significant titles and one of the greatest video games ever made. Nintendo Power magazine described aspects of the game as revolutionary, including its multiple endings, plot-related side-quests focusing on character development, unique battle system, and detailed graphics. The game's soundtrack, scored by Yasunori Mitsuda with assistance from veteran Final Fantasy composer Nobuo Uematsu, has been hailed as one of the best video game soundtracks of all time. Chrono Trigger was the second best-selling game of 1995 in Japan, and the various incarnations of the game have shipped more than 5 million copies worldwide.

The game has been re-released on several other platforms with varying differences. A port by Tose for the PlayStation was released only in Japan in 1999, which was later repackaged with a Final Fantasy IV port as Final Fantasy Chronicles (2001) exclusively in North America. A slightly enhanced Chrono Trigger, again ported by Tose, was released for the Nintendo DS in Japan and North America in 2008, and PAL regions in 2009. The game has also been ported to i-mode, the Virtual Console, the PlayStation Network, iOS, and Android. In 2018, a higher resolution version was released for Windows via Steam.

Gameplay Chrono Trigger features standard turn-based role-playing video game gameplay. The player controls the protagonist and his companions in the game's two-dimensional world, consisting of various forests, cities, and dungeons. Navigation occurs via an overworld map, depicting the landscape from a scaled-down overhead view. Areas such as forests, cities, and similar places are depicted as more realistic scaled-down maps, in which players can converse with locals to procure items and services, solve puzzles and challenges, or encounter enemies. Chrono Trigger gameplay deviates from that of traditional Japanese RPGs in that, rather than appearing in random encounters, many enemies are openly visible on field maps or lie in wait to ambush the party. Contact with enemies on a field map initiates a battle that occurs directly on the map rather than on a separate battle screen.

Players and enemies may use physical or magical attacks to wound targets during battle, and players may use items to heal or protect themselves. Each character and enemy has a certain number of hit points; successful attacks reduce that character's hit points, which can be restored with potions and spells. When a playable character loses all hit points, they faint; if all the player's characters fall in battle, the game ends and must be restored from a previously saved chapter, except in specific storyline-related battles that allow or force the player to lose. Between battles, a player can equip their characters with weapons, armor, helmets, and accessories that provide special effects (such as increased attack power or defense against magic), and various consumable items can be used both in and out of battles. Items and equipment can be purchased in shops or found on field maps, often in treasure chests. By exploring new areas and fighting enemies, players progress through Chrono Trigger story.

Chrono Trigger uses an "Active Time Battle" system—a recurring element of Square's Final Fantasy game series designed by Hiroyuki Ito for Final Fantasy IV—named "Active Time Battle 2.0". Each character can take action in battle once a personal timer dependent on the character's speed statistic counts to zero. Magic and special physical techniques are handled through a system called "Techs". Techs deplete a character's magic points (a numerical meter similar to hit points), and often have special areas of effect; some spells damage huddled monsters, while others can harm enemies spread in a line. Enemies often change positions during battle, creating opportunities for tactical Tech use. A unique feature of Chrono Trigger Tech system is that numerous cooperative techniques exist. Each character receives eight personal Techs which can be used in conjunction with others' to create Double and Triple Techs for greater effect. For instance, Crono's sword-spinning Cyclone Tech can be combined with Lucca's Flame Toss to create Fire Whirl. When characters with compatible Techs have enough magic points available to perform their techniques, the game automatically displays the combo as an option.

Chrono Trigger features several other distinct gameplay traits, including time travel. Players have access to seven eras of the game world's history, and past actions affect future events. Throughout history, players find new allies, complete side quests, and search for keynote villains. Time travel is accomplished via portals and pillars of light called "time gates", as well as a time machine named Epoch. The game contains twelve unique endings (thirteen in DS, iOS, Android and Steam versions); the ending the player receives depends on when and how they reach and complete the game's final battle. The DS version of Chrono Trigger features a new ending that can be accessed from the End of Time upon completion of the final extra dungeon and optional final boss. Chrono Trigger also introduces a New Game Plus option; after completing the game, the player may begin a new game with the same character levels, techniques, and equipment, excluding money, with which they ended the previous playthrough. However, certain items central to the storyline are removed and must be found again, such as the sword Masamune. Square has employed the New Game Plus concept in later games including Chrono Cross and Final Fantasy XV among others.

Story Setting Chrono Trigger takes place in an Earth-like world, with eras such as the prehistoric age, in which primitive humans and dinosaurs share the earth; the Middle Ages, replete with knights, monsters, and magic; and the post-apocalyptic future, where destitute humans and sentient robots struggle to survive. The characters frequently travel through time to obtain allies, gather equipment, and learn information to help them in their quest. The party also gains access to the End of Time (represented as year ∞), which serves as a hub to travel back to other time periods. The party eventually acquires a time-machine vehicle known as the Wings of Time, nicknamed the Epoch (this default name can be changed by the player when the vehicle is acquired). The vehicle is capable of time travel between any time period without first having to travel to the End of Time.

Characters

Chrono Trigger six playable characters (plus one optional character) come from different eras of history. Chrono Trigger begins in 1000 AD with Crono, Marle, and Lucca. Crono is the silent protagonist, characterized as a fearless young man who wields a katana in battle. Marle, revealed to be Princess Nadia, lives in Guardia Castle; though sheltered, she is at heart a princess who seeks independence from her royal identity. Lucca is a childhood friend of Crono's and a mechanical genius; her home is filled with laboratory equipment and machinery. From the era of 2300 AD comes Robo, or Prometheus (designation R-66Y), a robot with a near-human personality created to assist humans. Lying dormant in the future, Robo is found and repaired by Lucca, and joins the group out of gratitude. The fiercely confident Ayla dwells in 65,000,000 BC. Unmatched in raw strength, Ayla is the chief of Ioka Village and leads her people in war against a species of humanoid reptiles known as Reptites.

The last two playable characters are Frog and Magus. Frog originated in 600 AD. He is a former squire once known as Glenn, who was turned into an anthropomorphic frog by Magus, who also killed his friend Cyrus. Chivalrous but mired in regret, Frog dedicates his life to protecting Leene, the queen of Guardia, and avenging Cyrus. Meanwhile, Guardia in 600 AD is in a state of conflict against the Mystics (known as Fiends in the US/DS port), a race of demons and intelligent animals who wage war against humanity under the leadership of Magus, a powerful sorcerer. Magus's seclusion conceals a long-lost past; he was formerly known as Janus, the young prince of the Kingdom of Zeal, which was destroyed by Lavos in 12,000 BC. The incident sent him forward through time, and as he ages, he plots revenge against Lavos and broods over the fate of his sister, Schala. Lavos, the game's main antagonist who awakens and ravages the world in 1999 AD, is an extraterrestrial, parasitic creature that harvests DNA and the Earth's energy for its own growth.

Plot In 1000 AD, Crono and Marle watch Lucca and her father demonstrate her new teleporter at the Millennial Fair in the Kingdom of Guardia. When Marle volunteers to be teleported, her pendant interferes with the device and creates a time portal into which she is drawn. After Crono and Lucca separately recreate the portal and find themselves in 600 AD, they locate Marle, only to see her vanish before their eyes. Lucca realizes that this time period's kingdom has mistaken Marle (who is actually Princess Nadia of Guardia) for Queen Leene, an ancestor of hers who had been kidnapped, thus putting off the recovery effort for her ancestor and creating a grandfather paradox. Crono and Lucca, with the help of Frog, restore history to normal by rescuing Leene. After the three part ways with Frog and return to the present, Crono is framed for kidnapping Marle and sentenced to death by the current chancellor of Guardia. Lucca and Marle help Crono escape prison, haphazardly using another time portal to evade their pursuers. This portal lands them in 2300 AD, where they learn that an advanced civilization has been wiped out by a giant creature known as Lavos that appeared in 1999 AD, and find the last remnants of humanity living in underground domes subsisting off of machine energy in place of food. The three vow to find a way to prevent the future destruction of their world. After meeting and repairing Robo, Crono and his friends find Gaspar, an old sage residing in an atemporal space known as the End of Time, who offers them the ability to travel through time by way of several pillars of light. (The party is able to challenge Lavos at any point after this scene, with completion of the game prior to its final chapter unlocking one of twelve different endings.)
