Flying inside one of Megalith's tunnels

"Megalith -Agnus Dei-" (or "Megalith - Agnus Dei -") is a song from the Ace Combat 04: Shattered Skies Original Soundtrack, featured as the 13th track on Disc 2. It was composed and arranged by Keiki Kobayashi for the final mission of Ace Combat 04: Shattered Skies, "Megalith". The song is regarded as one of the most popular from Ace Combat and has featured outside of the games in various ways, including official live performances, other video games, and internet memes.



"Megalith -Agnus Dei-"'s lyrics have never been officially released. Auditory analysis indicates the lyrics were drawn from the Requiem Mass, a religious service for the souls of those who have died. The Latin text commonly sung during a Requiem Mass, including Agnus Dei itself, has been used many times in musical arrangements.

The phrase "Agnus Dei" is Latin for "Lamb of God", a title given to Jesus as attested in the Gospel of John (specifically John 1:29: "Behold the Lamb of God who takes away the sin of the world").[1]

The specific text used in "Megalith -Agnus Dei-" is as follows:

Agnus Dei, qui tollis peccata mundi, dona eis requiem.
Lux æterna luceat eis, Domine:
Cum Sanctis tuis in æternum:
quia pius es.

The above Latin text translates to the following English text:

Lamb of God, you who takes away the sins of the world, grant them rest.
May light eternal shine upon them, O Lord,
with Thy Saints for evermore:
for Thou art gracious.


"Rex Tremendae" plays in the cutscene immediately preceding the mission; its lyrics are the eighth stanza of "Dies irae", another Latin sequence used in Requiem Masses. "Heaven's Gate" plays in the Mission Update where Megalith's central heat vent opens up. The mission itself is referred to in-universe by the Independent State Allied Forces as Operation Judgement Day, referencing the belief in Judgment Day and the Second Coming of Jesus.

These connections to Christian mythology present the player character, Mobius 1, as an allegory for Jesus, the sacrificial Lamb of God sent to eliminate the sins of the world. Megalith, the weapon of mass destruction and the epitome of Erusea's "sins", represents the megalith upon which Mobius 1 is to be sacrificed. The game subverts the allegory when Mobius 1 survives the battle.
