"The rampaging flying fortress is a sign of invasion. Entrusted with the Singing Fairy’s power, the Armed Blue spreads his wings once more, to prevent the peace they've gained from becoming a trifle..."
Infiltrator is Gunvolt's intro mission in Azure Striker Gunvolt 2, taking place within the stage Seraph Interior. Strongly suspecting that Eden is responsible for the ship going out of control, Xiao sends Gunvolt aboard to investigate.
Banking 1000 or more kudos in the stage as Gunvolt will unlock Joule Audiolocket 1, which when equipped causes Indigo Destiny to always play when reaching 1000 kudos.
Non-canonically, Copen can also go through this stage in his version of Secret Mission 1 and Score Attack Mode after the story is complete.
The first room contains three Sumeragi grunts that just stand there scared. Sparing them will grant a 111 secret kudos bonus and some praise from Joule, although this is less than the triple bonus that can be gained by defeating them.
This stage also teaches gimmicks involving Flashfield, such as zapping electric panels to lift giant doors.
This is the only stage where Sumeragi enemies run the show. Every stage after this is completely Eden's show (exceptforTeseo's).
The area after the first Hexapyle will forcibly activate Anthem. You'll need it to blast your way through the mobs AND outrun whatever Teseo does to the airship.

Trivia
The sound effect that plays at the control room is identical to the one used aboard the Grand Nuage airship in Mega Man ZX, another game primarily developed by Inti Creates.
It is possible to survive Teseo's digitizing wall of light. To do this, GV/Copen must have very high HP from leveling up, use knockback preventing equipment (preferably with damage reduction), and charge through the wall as quickly as possible. They will come out behind it alive, but heavily damaged. This is possible because the wall is not actually a one-hit-kill, but rather inflicts very high damage per hit and ignores the invincibility frames triggered by being injured. This combination stunlocks and kills the player almost immediately as lethal damage racks up in less than a second, creating the illusion of instant death.
