Valkyria Chronicles 4 is a tactical role-playing game developed and published by Sega, with assistance from Media.Vision. It was released in Japan for the PlayStation 4 in March 2018, and worldwide, in addition for the Xbox One, Nintendo Switch, and Microsoft Windows, in September 2018.
Gameplay
Valkyria Chronicles 4 is a strategy game in the style of the first three games in the series. It introduces a new soldier class known as the Grenadier, who can fire mortar rounds at enemies. If allied soldiers are present to provide battlefield information, they can fire without being seen by hostile forces. When a soldier in your army is on the verge of death, there is a fixed chance that a new system called "Brave" will be activated. When used, players can choose to either restore one Command Point (CP) and increase the ability of a nearby ally, counter the enemy's attack (if downed on enemy's turn) or restore Action Points (AP) to the unit and enable the it to move and attack once in an invincible state (if downed on player's turn).
Plot
Claude Wallace and his childhood friends Kai Shulen and Raz join the Federation Army in order to fight the Empire in the Second Europan War, both to protect their home country of Gallia and avenge an Imperial attack on their hometown of Hafen. However, during training, Kai mysteriously disappears, leaving his sister Leena to take his place as "Kai". Claude, Raz, and Leena are able to pass training and join the elite Ranger Corps, with Claude being assigned command of Squad E.
Squad E is then informed that the Empire has the upper hand, capturing a large amount of Federation territory as well as initiating an invasion of Gallia. Federation leaders decide to put all of their resources into Operation Northern Cross, a massive offensive with the objective of pushing straight to the Imperial capital of Schwartzgrad. The operation is initially successful, with Squad E managing to push through Imperial territory. Along the way, they are joined by another childhood friend, Riley Miller. Riley is initially mistrustful of Claude due to him running away from a fire that killed Riley's family, but eventually accepts his command when he proves his worth as a leader. Squad E continues the offensive by breaking the Siegval Line, Schwartzgrad's final line of defense.
Along the way, they battle the elite Imperial tank unit Ausbruch, led by Klaus Walz, who considers Claude a worthy rival. However, despite the Federation's early success, winter comes earlier than expected, halting the unprepared Federation forces. Crippled by the snow and cold and weakened by stretched supply lines, the Federation forces are quickly routed by a massive Imperial counterattack. Squad E is forced to flee to the coast, where they are rescued by a trio of highly advanced Federation snow cruisers; massive warships that can travel over the ice of the Crystal Sea.
After coming aboard one of the cruisers, the Centurion, Claude is assigned by Captain Morgen to protect the warship as the fleet carries out Operation Cygnus, a contingency plan to attack Schwartzgrad from the sea in case Operation Northern Cross failed. Meanwhile, Walz is assigned to X-0, an elite Imperial science unit led by Lord Heinrich Belgar. Belgar tasks Walz with intercepting and capturing the Federation fleet, and teams him up with his chief strategic officer, Forseti and the Valkyria Crymaria. Forseti leads an attack on the fleet, prompting Squad E to respond, but Crymaria intervenes against Forseti's orders, and she loses control of her powers, destroying one of the cruisers and heavily damaging the Centurion before it escapes. Forseti is furious since their mission was to capture the cruisers intact, and he reveals to Walz that he has planted his sister as a spy aboard the Centurion in order to track its movements. Walz then witnesses how Crymaria is mistreated by her handlers and begins to show her compassion.
Meanwhile, the crew of the Centurion tries to repair the damage to their ship, but its main reactor has been knocked offline, forcing the ship to run at a fraction of its speed on the backup engine. At the same time, Riley finds a young amnesiac girl named Angie in the engine room, and the crew assumes her to be a stowaway. Squad E begins to take a liking to Angie as she befriends everybody. During a raid on an Imperial supply base, Angie sneaks ashore and meets Crymaria, who realizes Angie is a Valkyria as well. It is also revealed that Forseti is the real Kai, now working for the Empire and manipulating Leena into spying for him. Leena decides to cut ties with Forseti, declaring her brother dead. Claude then receives word that the third ship in the fleet is under attack. Despite knowing it is a trap, Squad E attempts to rescue the ship, but it self destructs, creating a massive explosion. Knowing that the Centurion can't escape the blast unless at full speed, Angie places herself inside the reactor, revealing herself to be the power source. Captain Morgen is wounded during the fighting and reveals the true scope of Operation Cygnus to Claude. The reactors that power the snow cruisers use energy given off by Valkyria placed inside them. In addition, the reactors also double as weapons dubbed the "A2 bomb", powerful enough to destroy an entire city. Operation Cygnus' true objective isn't to invade Schwartzgrad, but completely destroy it with the A2 bomb.
Claude is placed in command of the Centurion and he reluctantly proceeds with the mission. Walz and Crymaria attempt to stop him but are defeated. Crymaria loses control of her powers again after believing Walz was killed, but he appears and helps calm her down, promising her that they will live a happy life together after the war. The Centurion continues towards Schwartzgrad but is caught in a trap. Raz sacrifices himself to disable the trap and the ship continues on, plowing into the center of Schwartzgrad. Forseti boards the ship, intent on rescuing Angie since he had previously been part of the secret Federation program to acquire Valkyria for the reactor experiments, and his guilt motivated him to defect to the Empire. Leena shoots and kills Forseti before he can reach the reactor. Claude then prepares to detonate the A2 bomb, but the Empire offers a ceasefire to the Federation, ending the war with no clear victor. Belgar ignores the ceasefire and attacks the Centurion, obsessed with seizing its reactor and perfecting the technology. Squad E is able to defeat and kill Belgar, but the Centurion is severely damaged and begins to sink. Claude is able to narrowly rescue Angie and Riley from the sinking ship.
Afterwards, the Second European War comes to an end with neither the Federation nor Empire achieving a decisive victory, but everybody is glad to see peace return. Walz lives happily with Crymaria at his side. Squad E disbands and the survivors pursue their own interests while Claude, Riley, Leena, and Angie return to Hafen to live in peace.
