Sanctify

Sanctify is a mission in Ace Combat: Joint Assault.

Plot
The International Union Peacekeeping Force plans to launch an assault on an abandoned Soviet Union missile silo occupied by the Valahia in Central Asia, which they have dubbed "Infern", a Romanian word for "hell". The group has made numerous demands to the main global powers, which they backed with threats of nuclear strikes on Europe and the United States.

Martinez Security and the IUPF have planned to assault Infern before the missile launch preparations are complete, dealing the killing blow to the weakened Valahia in doing so. Their plan involves the M42 Antares Squadron entering Infern airspace and establishing air superiority, thus allowing ground forces to move in and attack the facility.

At 15:00 PM, the Antares team arrives to the Valahian base, and are met by the Varcolac Squadron. Their leader, Milosz Sulejmani, gives them a message from the Valahian commander Nicolae Dumitrescu, telling them that they are in the final stages prior to launching a nuclear attack on America and Europe. Having spoke his message, he directs his attention to Antares One and challenges him to a fight to see if he has what it takes to "become a hero."

In the ensuing battle, Milosz is swiftly defeated and shot down by Antares, his wingmen shaken by the loss of their commander. The rest of the Varcolac Squadron soon follows suit and is destroyed, however all pilots manage to survive the fight.

At the end of the confrontation, Fredric Burford congratulates the Antares Squadron for their actions, only to be alerted by the squadron's flight operator that the Valahian missile launch will occur shortly. With little time remaining, Burford calls off the ground attack, and orders Antares Squadron to fly into the missile silo itself.

Flying inside the fortress itself, Antares destroys a steel door blocking the tunnel and enters the missile silo area. Destroying control switches around the structure interior, he reaches the core of Infern itself, while Dumitrsecu taunts him, describing how the Valahia is merely part of a larger plan, and disables a central control facility, causing the infrastructure of the base to collapse. The pilot barely escapes from Infern before the missile silo explodes, killing Nicolae and the commanders of the Valahia.

Antares reunites with Burford, monitoring the situation from an E-767, and several escort aircraft. Burford comments on the "Golden Axe Plan" mentioned earlier by Dumitrescu. Having realized the plan's true nature, he tell Antares that they must travel to the United States to stop the plot, which leads to their defection from Martinez Security.

Walkthrough
The player begins in the proximity of the Infern base. Shortly afterwards, the Varcolac Squadron will appear, and after a short dialogue will challenge Antares to a fight. Sulejmani's wingmen will remain untargetable for the moment, so concentrate solely on their leader.

Fighting Milosz will not be a difficult task; get on his tail and relentlessly attack until the "destroyed" notification appears. Another valid tactic consists of opening fire at the end of his "final declaration" speech, at which point his formation is flying in a straight line. Either way, after he is defeated, his wingmen will become targetable. Down them all to proceed to the next phase.

After the cutscene, Antares appears inside the entrance to the missile silo. There is just enough space for you to move around, so do not panic. Target the "Switch" ahead of you to open the door blocking your path. Upon reaching the large site after silo A, fly up and take out the switch near the ceiling, being careful not to fly too fast as you descend. Fly through the next tunnel and eliminate the third switch. Pass through the silo and go through the tunnel.

Upon reaching the core of the base, destroy the two "Facilities" targets. One will be in front of you, while the other will be near the roof, by the pillar. Destroy both targets and the mission will conclude in a cutscene.

Trivia

 * Shooting down a Varcolac member which trigger unique responses from their peers, depending on which pilot was defeated. For example, downing Tolya Kiriakov will cause Daniel Oruma to exclaim "Tolya, no! You gotta be kiddin' me!".
