Retake the ARCAM Lab

*Retake the ARCAM Lab* is the eleventh campaign mission of Spriggan: Lunar Verse. The ARCAM research institute is under attack by someone. It appears that they are attempting to be after its underground vault. Tatsuki must fend off the invasion and prevent the items within the underground vault from being stolen.

## Briefing

Graham states to Tatsuki that the former received word about the ARCAM institute currently being under attacked by someone. It appears their intention leans towards the contents within the underground vault. Graham appears to overestimate the efficiency of the building's security system, believing that even if a platoon were to invade the institute, the security wouldn't be breached. If the enemy were to be successful in taking what's in the vault, it would spell disaster for the ARCAM corporation. Before closing the briefing, he tells Tatsuki that they are not going to let that scenario happen.

## Mission Overview

Tatsuki is seen hanging from the helicopter's rope ladder arriving at the ARCAM's building. The pilot gives a statement that the situation isn't looking good. He forms a plan that he'll take Tatsuki to the top of the building where he can jump off to there. The pilot admits to him of his concern for the underground vault, before the latter jumps down to the rooftop. Tatsuki is immediately attacked by two modified lycanthropes containing wings on their backs upon arrival. Once they are dealt with, he heads to the helipad section where he encounters Trident troops attempting to hold him off to the underground vault. Tatsuki eventually finds a key, which is needed to unlock the door leading to inside the ARCAM building. Tatsuki uses the key on the door and proceeds to head inside the building.

Tatsuki discovers the building is in high alert with modified lycanthropes, fires, and Trident soldiers occupying the building's halls. Tatsuki explores the section where he is currently at and takes the elevator that brings him to the lower level. Upon exiting it, he is contacted by Graham, stating that he discovers the intruder's identity from the footage left in the security system. The intruder's name is revealed to be Leticia Dale, head of the Trident Weapons Development division. He believes that they are aiming for the underground vault, so he orders Tatsuki to pick up the pace. Tatsuki heads to there, defeating any enemies he comes across. As he approaches the elevator leading to the underground, he is alerted by the ARCAM researcher, who appears to be mortally wounded in the small room. The researcher informs him that they are already in the underground vault. He requests him to hurry up, before succumbing to his wounds. Tatsuki kills the gargoyle-like lycanthrope guarding the elevator and proceeds to it.

Tatsuki arrives to the underground section and quickly runs to the vault. There, he finds Rock Vampire, the same opponent that he fought back at the ruins, leaning against the vault door which is already opened. He admits that he is surprised to see Tatsuki arriving unexpectedly early. By then, Leticia reveals herself as she comes out from the vault's room with the OOParts in her hands. She notices Tatsuki, but immediately disregards him with the statement that she has no time to deal with him right now. He orders Rock to take care of him for her before leaving the underground. Tatsuki, presumably, is about to intercept her before being grabbed attention by Rock, telling him that it's him he is dealing with right now. He informs him of his mistake about letting his guard down in their previous engagement, but this time it'll be different. Shortly afterwords, he transforms into his werewolf form, and challenges Tatsuki into an one-on-one duel. He manages to defeat Rock, and receives a communication call from Graham about a terrifying news when he was searching for a recoverable data left in the security system: apparently, bombs have been planted in the lab by Trident special forces. He informs Tatsuki that he doesn't have much time to disarm them, so he has to hurry. The latter heeds his boss's warning, and runs to the elevator to the upper floor.

Tatsuki only has four minutes before the bombs explode, in which even a single bomb is enough to destroy the entire lab and possibly the entire ARCAM building. There are five bombs that are placed, some of which are more hard to see than others. In addition, disaster prevention shutters were activated, forcing Tatsuki to destroy them if he desires to bypass through them. After disarming the last bomb, Graham provides a confirmation that it appears all the bombs are disarmed, and a potential disaster for the destruction of the ARCAM building has been prevented.

## Debriefing

Graham discovers two things taken from the vault were the Crystal Soul Stone and the Crystal Purity Jade originally recovered from their respective ruins. These are the official names given by ARCAM. Given the fact that Leticia didn't steal the rest of the vault content, it was clear that those two OOPArts were her main objective. Afterwards, Graham provides additional information on Leticia's background: Dr. Dale formerly worked with the U.S. Army, where she collaborated with a man who would be her future fiancé. Both were studying the technology of ancient civilization. They eventually formed a theory that the moon is apparently a man-made structure built by them. At one point, Dr. Dale's fiancé died in an accident during an experiment, and she was then transferred to Trident, where she remains to this day. Graham admits that those two artifacts aren't analyzed by ARCAM as being of significant values, but still theorizes that if Dr. Dale manages to travel all the way to the vault herself, it can be assumed that something serious is going on.
