Setting Ace Combat 6 is set in the series' fictional universe of
Strangereal, where Earth has entirely different nations, geography, and history. The game's story follows a war between the fictional countries of Emmeria and Estovakia on the northern continent of Anea in 2015. Sixteen years prior, a global
asteroid impact event devastated Estovakia, but its neighbor Emmeria was left unscathed and continued to thrive. A
civil war broke out in Estovakia, after which a
military junta known as "The Generals" soon seized control of Estovakia and began preparations to invade Emmeria. Players control Emmerian
fighter pilot "Talisman". Alongside Talisman's
wingman, Marcus Lampert, callsign "Shamrock", the pair make up the two-pilot squadron "Garuda Team". Other main characters seen in cutscenes include Lt. Col. Victor Voychek, an Estovakian ace pilot-turned-
intelligence officer; Melissa Herman, an Emmerian refugee searching for her missing daughter Matilda; Ludmila Tolstaya, an Estovakian civilian seeking to reunite with her fiancé Toscha, an Estovakian pilot; and "Serval", an Emmerian
tank unit consisting of Louis McKnight, Donnie Torch, and Kevin Hobsbawm, who plan a bank heist behind enemy lines.
Plot In 2015, the Emmerian capital of Gracemeria is attacked by Estovakia. Emmerian forces scramble to defend Gracemeria, including Talisman and Shamrock, who form Garuda Team due to neither pilot having a wingman. As the battle begins, Melissa witnesses Estovakian aircraft destroy the bridge that Matilda's school bus is supposed to be crossing. The battle is interrupted by a
cruise missile barrage from Estovakia's
airborne aircraft carrier P-1112 Aigaion and elite "Strigon Team" squadron led by Lt. Col. Voychek, forcing the Emmerians to withdraw. Melissa, fleeing alongside other Emmerian refugees, learns her husband, an Emmerian fighter pilot, was killed in action. Later, Melissa hears Matilda's voice in a radio broadcast from Estovakian-occupied Gracemeria and begins a journey back to the city to find her. Voychek, injured after being shot down by Garuda Team, is reassigned to interrogate Emmerian
POWs, but they only taunt him to "go dance with the angels", a phrase from Matilda's broadcasts used as a slogan of defiance by the Emmerians. Over the next three months, Emmerian forces retreat westward under Estovakian attack, before regrouping at Khesed Island to launch a counterattack. Garuda Team supports the counteroffensive, but their advance is once again stalled by cruise missiles launched by the Aigaion, which Garuda Team eventually destroys. Meanwhile, Melissa meets and befriends Ludmila, who joins her to find Toscha; Serval plans their heist and gives Melissa and Ludmila a ride to Gracemeria when they cross paths; and Voychek discovers a group of rebel children, including Matilda, hiding in Gracemeria's ancient
catacombs, but they are trapped in a collapse. As Emmerian forces approach Gracemeria, a ceasefire is suddenly called after Estovakia threatens to deploy chemical weapons on Gracemeria in a
scorched earth defense should Emmerian forces advance further, but Garuda Team destroys Estovakia's chemical weapon stockpiles. After intense
combined arms urban warfare, the Emmerians liberate Gracemeria, while Garuda Team defeats Strigon Team and their new leader Ilya Pasternak. Melissa and Ludmila reach Gracemeria alongside Serval, who inadvertently rescue Voychek and the children after mistaking the catacombs for a bank vault; Melissa reunites with Matilda, while Serval gives up on the robbery and recovers royal artifacts from the catacombs to inspire the populace. During a post-liberation patrol over Gracemeria, the city is suddenly attacked by long-range cruise missiles, which Garuda Team intercepts. With assistance from Melissa, Matilda, and Voychek, the Emmerian military traces the attack to the "Chandelier", an Estovakian
anti-asteroid railgun repurposed to destroy Gracemeria. Emmeria launches an operation to destroy the Chandelier, and Shamrock sacrifices his plane to expose the facility's weak point for Talisman to destroy. The Generals are overthrown, and the new Estovakian government negotiates peace with Emmeria, ending the war. Ludmila and Toscha marry in an
internment camp with Voychek attending, while Shamrock is revealed to have survived the final battle. As he visits the Herman household to meet Melissa and Matilda, Shamrock muses that peace between nations was what they had always been fighting for, and that it had finally come. ==Downloadable content==
