Missions ( Crisis Core ) / Great Cavern of Wonders The general " story " of the missions in this set is that Shinra has uncovered a new set of caverns near the northern cave . Investigation is wrought with difficulty due to both Genesis and Wutai remnants attempting to loot the caverns , as well as the presence of the local monster population , which is strangely overpowered . Machines , infantrymen , and others are used to protect the civilian employees , but a mysterious force seems to turn both defeated machines and humans against their former side . Ultimately , only Zack is remaining ( with all other Shinra , Genesis , and Wutai troops either retreated or lost ) and continues further into the caves . This culminates in the last mission , where the source of the mysterious force is shown to be the game ' s superboss . Invitation to the Underground . Underground Caves . " We unearthed a second subterranean den near the northern cave . We cannot determine whether it was naturally formed , or made by human hands . Shinra sent a science team , which never came back . This is where you come in . " Deeper into the Caves . " The caves are larger inside than previously thought . Headquarters has decided on a thorough investigation , but this is going to be a long - term mission . Proceed slowly and with caution . " Marks of an Intruder . " Evidence of human life has been found deep inside the caves . We are obviously not the first ones in . Investigate the surrounding area ; if you encounter any hostiles , you are free to eliminate them . " Genesis ' s Interception . " We are still unsure of Genesis ' goals , but the fact that he has deployed troops to these caves indicates that something inside interests him . Eliminate Genesis ' forces while exploring the caves . " Behind the Scenes . " A SOLDIER operative in our investigative unit has been taken out by Genesis troops . Hurry to where the SOLDIER operative was deployed , and eliminate the enemy . " Genesis ' s Threat . " Genesis troops have proven to be stronger than initially imagined . They must be neutralized for our investigation to move forward . Eradicate the enemy in the surrounding area . " Stirrings . The Third Power . " We have received reports that there is a third party , other than Genesis troops , in the caves . Head immediately to the area , confirm their identity , and if hostile , eliminate them . " Weapons Out of Control . " Gun Bull Heads have been sent on to fights against both Genesis and Wutai forces , but something has made the machines unable to distinguish between friend and foe . We have no choice but to enter the deployment area and destroy our own machines . " Continuing into the Caves . " This is another request for an investigation into the caves . All reports suggest Genesis ' forces are still active . You must proceed with the investigation while eliminating the enemy . " A New Path Discovered . " We have reports of a new route found inside the caves . We assume neither Genesis nor Wutai forces are aware of this path as yet . Commence your investigation immediately . " To the Lower Levels . " We learned much from the previous mission , including how to descend to lower levels . We have decided for you to continue your investigation . Begin your mission immediately . " Signs of Materia . " A strong materia reaction has been detected inside the caves ; some sort of materia may be buried in the soil . Please head to the site and collect the materia . " In Search of What ? To the End . " The full scope of the caves still eludes us . The subterranean depths keep growing larger , and we have no choice but to explore them bottom to top . Go to your assigned area and begin the investigation . " Genesis ' s Challenge . " Activity by Genesis troops has been confirmed deep in the caves yet again . They seem to be conducting a search inside the caves armed with new weapons . Head to where they were last seen and eliminate them . " Genesis ' s New Weapon . " The new weapons in Genesis ' arsenal seem to possess overwhelming power . These must be destroyed to halt enemy ' s offensive . Move to their position with all haste . " Genesis ' s Super Weapon . " Genesis troops have readied stronger weapons , and only a SOLDIER 1st Class can survive their attack . Infiltrate the caves and destroy the prototypes before they get the chance to go online . " Wutai ' s Best . " Wutai troops thought destroyed have been sighted in the caves . Their best troopers have quietly moved to lower levels of the caves . Their goals are unknown , but we must halt whatever plans they have . Vanquish the Wutai elites . " No More Wutai . " The Wutai in the caves have been eliminated . Let us take this opportunity to further explore the deeper levels . Monsters have been confirmed as present , so you must continue fighting as you move downward . " Realm of Demons . Genesis ' s Ambition . " Genesis troops are advancing again . Their new frontline weapons are dealing massive damage , but yielding the caves to them is not an option . Vanquish this worthy enemy now ! " Genesis ' s Passion . " New Genesis copies , using tactics we ' ve never encountered before , are readying an army and marching into the caves with unstoppable momentum . Pursue them and stop their advance to prevent them from achieving their sinister goals . " A Fresh Start . " Genesis troops are no more . Wutai forces have vanished . There is nothing left to do but keep moving deeper into the depths of the caves . " Machines Gone Haywire . " Shinra ' s weapons are acting up ; something in the caves is making them go berserk . Destroy our machines to keep them from hurting our own people . " Only for SOLDIER . " Our own machines have gone berserk , and the losses we experienced are unacceptable . We are pulling our troops out of the caves , but SOLDIER must keep moving forward . Take out any monsters in your way ! " Only for 1st Class . " The monsters we ' ve encountered are so ridiculously powerful that SOLDIER operatives are struggling to stay in the fight . 2nd and 3rd Class operatives cannot go any further . We ' re counting on you . " Unknown Energy . Hojo ' s Monsters . " It seems monsters have been released from Hojo ' s lab into the caves . They are unlikely to distinguish friend from foe . Though we may be breaching the chain of command , you are permitted to fight back if they attack you . " Further Below . " We are thoroughly impressed that you have eliminated Hojo ' s monsters - no offense to him . With your abilities , we are confident that you can handle any foe that comes in your way . Keep up the pace and move forward . " Unusually Strong Monsters . " If our data is correct , these monsters are unusually strong ; the caves must be the cause . We are analyzing the monster data from the areas we have already covered , but it ' s not enough . Please go deeper and collect more data for us . " Abnormal Power . " We are fairly certain that the monsters inside the caves are being strengthened by an unknown energy . The energy seems to grow as we advance further down . Descend to the next level and help us find the cause . " Note : The Net Shop Shade is the only way to obtain the Genji Helm which gives a constant No AP or MP Cost and Libra in battle . Once shop is unlocked , players can buy the Genji Helm for 1 million gil . A Lonely Journey . " You are the only one left exploring these caves ; any other SOLDIER 1st Class operatives have long since retired . The monsters are becoming increasingly vicious . Proceed with caution . " Even Deeper . " We have confirmed the existence of Guard Hounds from the area you covered in the last mission . They may have gone berserk by themselves , but it is more likely that there was an external stimulus . Please gather more information as we continue to analyze our data . " Doors to the Unknown . Toughest Monsters . " An analysis of the data tells us that the monsters in these caves are exponentially stronger than they are above the ground . Even those that are relatively docile above ground become belligerent in these caves . We trust you , but do not let your guard down . " The Lowest Tier . " You have almost reached the lowest level of the caves . We will give you all the support we can . You may look forward to this mission ' s compensation . Good luck . " Weapons Gone Haywire . " It is now clear that the mysterious energy can influence not only monsters , but machines as well . The mechanical weapons go on unprogrammed rampages powered by a seemingly endless supply of energy . You ' re the only one who can solve this mystery . " Biomechanical Threats . " Though mechanical , the Master Blades you encountered in your last mission had taken on biological behavior from the unknown energy . The energy seems to have properties beyond our imagination . It ' s almost within your reach ! " Life Form of Energy . " Analysis of the mysterious energy has led us to believe that not only does it make machines behave like living organism , but any other life form killed by it could take on an entirely different behavior . Evidence suggest that a few of our men have disappeared in the lower levels . Don ' t let anything take you by surprise ! Keep your courage up and move forward ! " The Reigning Deity . " After the mysterious energy ' s influence , we are sure that its source is just beyond here . There ' s no telling what you may find , but we ' ve come too far to turn back now . We look forward to reading your report , Zack ! "
