''Atriox dismissed Pavium and Voridus as both leaves. Atriox take a look at the ruins of High Charity once again before turning it off. Pavium looks at Voridus while walking down the hallway.''
 * Pavium: "Do not disobey your orders again."

Voridus chuckle and Pavium stopped him angrily.
 * Pavium: "Scout the shell, salvage the ships. That is it. Atriox was clear!"
 * Voridus: "I'll look around. And if we find prizes to bring it back, how could that go wrong?"

''Both Pavium and Voridus equip their weapons. Pavium warns Voridus about what happen if he mess up again.''
 * Pavium: "Voridus, listen, you fail him one more time trying to prove yourself and i will not be able to save you... and it will be both our skulls beneath his mace."

They bump armfist and Voridus heads out for salvage operation.
 * Voridus: "Relax, brother. You worry too much."

Pavium sighs as he watches Voridus leaves.

HIGH CHARITY CRASH SITE

WHAT COULD GO WRONG?

Mission Briefing
 * Voridus: "Pavium, we are ready to move to High Charity. My men are impatient for glory."
 * Pavium: "Put a leash on them, Voridus! The terrain here is unsuitable for our power extractors. I am still working on a solution! And your men would do well to remember that whatever we find here belongs to Atriox."
 * Voridus: "This war has tamed you, brother! Where is your Jiralhanae lust for adventure? That relic is ripe for plunder!"
 * Pavium: "This war has taught me, Voridus. Stay your hand. Once we reach High Charity we need to move quickly to avoid wrath of the Sentinels defending it."
 * Voridus: "Yes, yes. I am well aware of what we face here. Hurry your preparations, old one. I already have troops on the ground! Voridus, out."

Scouting Report

Field anti-air units to combat the heavy Sentinel threat.

Gameplay
 * Brute Squad Leader: "This way, whelps, there's weapons to be salvaged from High Charity and Voridus commands us to return to base for new orders."
 * Grunt 1: "Did you say High Charity? The Covenant capital-place? I heard it was haunted! Scary monsters everywhere!"
 * Grunt 2: "Whoa, man. Back off the gas."

Banshees are flying through them as they advance.
 * Brute Squad Leader: "Silence! Those Covenant lies do not concern me and that means they do not concern you!"

Ahead another squad of Banshees are engaging Aggressors Sentinel.
 * Pavium: "Voridus, there are many Sentinels amassing here near the salvage site. They may be guarding, rather than protecting something within High Charity."

Spirits went through pass them while Banshees defeats the Sentinels.
 * Voridus: "The old stories of the parasite? Nothing but Covenant propaganda, old friend."

Approaching some unsalvaged resources, the Banished takes it.
 * Voridus: "You handle the Sentinels near you and let me deal with the ones here. We'll have what we need in no time."

''Approaching the site from the cliff, the Banished's air force engages the Sentinels. One Aggressor Sentinel is seen chased by two Banshees and the Grunt welp in joy. The scene of High Charity in ruins can be seen.''
 * Grunt 1: "Whoa, thats a lotta of Sentinels!"

The Jiralhanae smack the Grunt down to silence him.
 * Voridus: "Pavium, our air forces are engaging Sentinels near High Charity."
 * Brute Squad Leader: "Gah! What fool turned off the lightbridge?"
 * Grunt 1: "Aw, too bad. Guess someone else will have to deal with those Sentinels."

Reaver assists Banshees that are engaging multiple Aggressor Sentinels.
 * Brute Squad Leader: "Cowards! I shall punt you into the void! Reavers, re-activate the lightbridge!"

''Reavers leap through the chasm and arrived at the other side, activating the lightbridge. Once activated, the Banished continue to advance but they are blocked by High Charity debris.''
 * Grunt 1: "Ooh, Covenant stuff. Retro!"
 * Voridus: "Troops, I'm sending a Locust to clear the path."

''A Spirit drop a Locust while a Lich and another Spirit went pass through them. Locust immediately goes to work to destroy the debris.''
 * Grunt 2: "We turn back?"
 * Brute Squad Leader: "You can return with salvaged goods, or on a platter as a meat for the real soldiers. Your choice."
 * Grunt 2: "Choice made! Let's blast it!"

Once debris is destroyed, they continue ahead and found a squad is scanning the Covenant supply.
 * Brute: "Brothers! We've found these Covenant supply cases on our way to the base."
 * Brute Squad Leader: "Then don't waste timewith your scanning toys! Smash it open!"

They destroy the caches and obtained some supplies.
 * Brute Squad Leader: "See how easy that was? Now come with us!"

Continue ahead, they spot a Grunt Squad is under attack by Aggressor Sentinels.
 * Grunt 1: "Agh! Robot things!"
 * Brute Squad Leader: "Sentinels! Reavers, destroy them!"

''Once defeating them, they continue to advance and found some supplies near the portal that was not used again. Continuing ahead, more Aggressor Sentinels inbound.''
 * Brute Squad Leader: "More of those cursed machines!"

Some Aggressor Sentinels approach them from behind.
 * Brute Squad Leader: "They're behind us now! Stay alert!"

Defeating all of them, they continue to push forward and another squad is scanning the supplies before destroying it.
 * Brute: "This way, brothers! Our base is up ahead!"

Upon reaching the base, the Sentinels had already engage the base.
 * Voridus: "The Sentinels are attacking our base!"
 * Pavium: "Voridus! The Orbital Designator shows they're coming from a nearby launching bay."

A launching bay can be seen as Aggressor Sentinel and Protector Sentinel are coming out from it.
 * Voridus: "Fear not, Pavium. One of my new toys should handle them. Fire a Distruption Emitter at the launching bay. It's EMP field will stun those Sentinel!"

Calling a Disruption Emitter, the Sentinel are stunned once it lands.
 * Voridus: "Now, hit them while they are defenseless!"
 * Pavium: "Voridus, the EMP field from that emitter is fluctuating."
 * Voridus: "I made a few improvements and now it affects a much larger area."

Countdown start from 5 minutes to prepare the base.
 * Pavium: "Your 'improvements' have shortened the duration of the EMP itself. You will need to replace it soon!"

Once clear, the Banished clear the area from Sentinels and preparing the base.
 * Pavium: "Voridus, my Orbital Designator is yours upon request. It will help you spot those launching bays."
 * Voridus: "Get that base upgraded, we're going to need to build defenses!"

The turrets are not being upgraded yet while the Banished continues to assemble army and preparing the base.
 * Voridus: "We will need anti-air defenses to deal with the Sentinels! Upgrade the turrets!"

On the minimap shows where the Sentinels are headed to.
 * Voridus: "Be watchful of the launching bays! We cannot let the Sentinels overrun us! Make sure we have Reavers on the ground as well."

The timer reaches two minutes while the emitter goes weakened further.
 * Voridus: "We need another emitter, get one ready!"

''Checking around the base, they found another launching bay nearby but two Forerunner Turrets are defending it. The Banished land another Disruption Emitter to stun it.''
 * Voridus: "There's a launching bay close by! We must stun it!"

The timer to prepare the base reaches 0.
 * Pavium: "Voridus, you're going to be facing more Sentinels than we ever have before. Tell me you have a plan."
 * Voridus: "I'm putting it into action right now!"

A Scarab lands on the field.
 * Pavium: "Very subtle."
 * Brute: "Voridus, we have placed the markers to show the route for your Scarab!"

Scarab Health start to shown on the screen.

The Disruption Emitter is need to be replaced again.
 * Voridus: "We've used up one of our emitters, replace it!"

All turrets finally constructed and upgraded with Anti-air Turrets.
 * Voridus: "Good, we've built turrets. Those will help protect our base as we make our way to High Charity."

The Scarab start to destroy the barricade.
 * Voridus: "There's still so much wreckage lying around High Charity, it's going to take me a while to carve through it. Next time the Covenant lose a war, I hope they clean up after themselves!"
 * Pavium: "We should proceed with caution, Voridus. There are strange readings from inside the wreckage. You know the tales of the Gravemind and the corrupted it spread inside High Charity. If true, then it could be a greater threat than even the Covenant were."
 * Voridus: "More lies from the Prophets. Even if there was once such a threat, any "monsters" would be long dead by now."

The Sentinels start to engage the Scarab but the Banished quickly destroy them.

When the Scarab is under attack. or or or or or when Voridus is getting more irritated. or or
 * Voridus: "Protect your Scarab! Do your duty!"
 * Voridus: "I'm under attack! Act quickly!"
 * Voridus: "I'm under fire! Take care of it, NOW!"
 * Voridus: "Enough fun. Back to the mission!"
 * Voridus: "Do i have to tell you again? Protect your leader!"
 * Voridus: "I hate these things! Why must they plague me!"
 * Voridus: "Damn these infernal things."
 * Voridus: "Are you blind? The Scarab is under attack!"

The Banished defeat the Sentinels that attacking Scarab or that gets in their way. or or or or or
 * Voridus: "Fall before me! Hahah!"
 * Voridus: "See them burn! Hahah!"
 * Voridus: "HA! I hope you don't need that."
 * Voridus: "Hahahaha!"
 * Voridus: "Enjoy my plasma beam!"
 * Voridus: "Disapponting! I though the explosion would be bigger!"

The barricade's health reaches 50%
 * Voridus: "Halfway there! Keep firing!"

''The work continues while Banished continue to defend the Scarab. When the barricade reaches 25%.''
 * Voridus: "Almost there! Keep going!"

An emitter's duration has expired at one of the launch bays. or
 * Voridus: "One of our emitter has expired, prepare another!"
 * Voridus: "Prepare another emitter, we've used one up."

Another emitter dropped to stun the launching bay again while the wreckage has finally destroyed.
 * Voridus: "The wreckage has been removed! Move out on me!"

The Banished start advancing and encountered Forerunner Turrets on the way.
 * Voridus: "Pavium, we have encountered a new Forerunner defense system - Turrets!"
 * Pavium: "The area around High Charity is more fortified than anywhere else. It is clear we are treading where we should not."
 * Voridus: "The Banished go where they want and destroy any who oppose! Is Atriox's rise not proof of this?"
 * Pavium: "Atriox use cunning as well as strength. A wise warrior does not pick a fight with an unknown foe."

''They continue to advance and clearing any of Sentinels that gets in their way. Reaching another barricade, the Scarab start to work on it while the Banished defend it from Sentinels.''

When the barricade reaches 50%.
 * Voridus: "Structural integrity at fifty-percent!"

When the barricade reaches 25%.
 * Voridus: "The wreckage is nearly destroyed! Get ready to move!"

Second Barricade is destroyed and Banished continue advancing.
 * Voridus: "Wreckage destroyed! Move out!"

''Continue advancing, the Scarab destroyed the wreckage that allows the newly fresh Banished units to take the shortcut. Ahead, they found some UNSC's presence.''
 * Voridus: "The humans are here! They will not stop us from taking what we want! Wipe them out!"

Scarab and the Banished start to engage UNSC.
 * Voridus: "Pavium, the humans are here!"
 * Pavium: "What? If they crept beneath our scans their forces must be small. Simply reconnaisance mission."
 * Voridus: "Then i'll make sure they don't report anything back."

They found two UNSC 2-slot minibases and the Banished attacks the base.
 * Voridus: "Disable those turrets!"

UNSC start to call in supports by dropping ODSTs but the Banished quickly defeat them and destroying their bases.
 * Voridus: "The humans are sending in support! Make sure them regret it!"

A 3-slot minibase is avaiable for construction while the Scarab went to the third obstacle and start attacking it.
 * Voridus: "Clear those debris out and call in a new base! We'll need more troops to make sure this Scarab reaches High Charity!"
 * Pavium: "Voridus, from the size of that shell, it appears large portions of High Charity remain intact."
 * Voridus: "Which mean there are more weapons for us to plunder!"
 * Pavium: "Atriox warned us not to enter High Charity, Voridus. Focus on salvaging what remains around it."

On Pavium's side, the salvage drills becomes unoperable.
 * Pavium: "Voridus, I have run into the problems with the salvage drills. The power that runs under the surface here is surprisingly unstable. I'm not sure if our extractors could handle it in it's unrefined form."
 * Voridus: "I'm sure you'll figure it out, brother. That's why i keep you around!"

When the third barricade reaches 50%
 * Voridus: "We're halfway through the wreckage. Keep going!"

When the third barricade reaches 25%
 * Voridus: "We're nearly blasts through. Be ready to go."

The Scarab destroys the third barricade.
 * Voridus: "Wreckage clear! Let's get going!"

Continue advancing, there is a launching bay ahead and some aggressor sentinels arrive to ambush the Banished.
 * Voridus: "We're being ambushed! Disrupt that launching bay!"

''The Banished continue to punch through them while continue to escort the Scarab. Ahead they found 2-slot minibase and call in base drop to make a quick reinforce as they approach High Charity.''
 * Voridus: "We're almost at High Charity. There may be more resistance, bolster our forces!"

''Continuing ahead, the Scarab stopped as the lightbridge is out. The Banished activate it and the Scarab continues to advance. The Banished found some Sentinel Defense Network with more sentinels defending it.''
 * Voridus: "Pavium, I've found some kind of Forerunner interface and there are more Sentinels nearby."
 * Pavium: "Be careful Voridus. There is still much we don't understand about the Forerunners and their machines. You may make things worse."
 * Voridus: "Don't fret, brother. I can handle it. I'm going to investigate. Scarab Commander, continue smashing through that wreckage."

The Scarab start working on destroying the wreckage while Voridus try to disable the Sentinel defense network.
 * Voridus: "Protect the Scarab while i try and deactivate the Sentinel defenses!"

Voridus start working on the devices.
 * Voridus: "Voridus finds you wanting!"

While defending the Scarab, Voridus discovered the defense network that has security levels.
 * Voridus: "Aha! It seems to have several security levels and the first one should be broken when i do...this!"

The first level defenses are deactivated but the Sentinel start to attack more fierce than before.
 * Voridus: "It worked! That's the first level deactivated."
 * Scarab Commander: "Voridus! The Sentinel attacks have increased in ferocity!"
 * Voridus: "Come to see who's undoing your work, eh? Destroy them! I'm not finished here yet! Use the Disruption Emitter! Nothing must stop our Scarab!"

After breaking through wreckage and clearing Sentinels, the Scarab advances again.
 * Scarab Commander: "They're down. Now, let's get moving, our orders await!"

Ahead, multiple Forerunner Turret is trying to stop the Scarab.
 * Voridus: "Is this the extend of their defenses! Pah!"

Voridus figure out how to disable another defenses however the Sentinel has increased their defenses.
 * Voridus: "Yes, I've got it! Keep that Scarab moving. I've breached the second security level. I just need some time to deactivate it."
 * Scarab Commander: "Voridus, The Sentinels' numbers have increased again!"
 * Voridus: "Then deal with them! Use everything you have!"

If player spots a minibase close to the launch bay.
 * Voridus: "There's a prime location for a base expansion near that launching bay."

If the disruption emitter is ready but player does not want to use it.
 * Voridus: "What are you waiting for? Use a Disruption Emitter to stun any Sentinels launching from it!"

The Scarab continue to advance while the Banished continue to defend the Scarab.
 * Voridus: "Take the base so we can divide the Sentinels' focus and stagger their attacks! My Scarab must make it to High Charity in one piece!"

Voridus continue to work on defense network while some Reavers protect Voridus from Sentinels that are trying to stop him.
 * Voridus: "Every time i think i've solved it...wait, this looks promising."

Voridus continue to try disable the defense network.
 * Voridus: "Mysteries are what kept the Covenant blinkered and weak, we will smash through them!"

Voridus almost done with his work while Scarab continue to push on.
 * Voridus: "Almost there. Yes, this should be it."

The Sentinels are sending even more Aggressor and Protector Sentinel towards the Scarab.
 * Scarab Commander: "The Sentinels are sending even more against us!"
 * Voridus: "They're getting desperate! I must be close to completely shutting them down!"

The Scarab approaches the High Charity.
 * Scarab Commander: "We are approaching High Charity now, Voridus."
 * Voridus: "At last, Pavium! I hope your pack is ready to transport the riches we find nearby!"
 * Pavium: "Stay alert, you fool. There is a massive Sentinel wave flying in your direction!"

Reaching the destination, two Retriever Sentinel approaches Scarab and start attacking while the final puzzle appeared.
 * Scarab Commander: "Voridus! The Ark has sent Retriever to stop us!"
 * Voridus: "I tire of their interference! I'll use this thing to deactivate the Sentinel defenses once and for all!"

The Scarab start firing to Retriever but the Scarab is outgunned against it.
 * Scarab Commander: "Voridus! We're not doing any damage against those Retrievers. How we will stop them?"

If player takes too long to solve he final puzzle. or or
 * Scarab Commander: "We need those defenses shut down, Voridus. These Retrievers are unstoppable!"
 * Scarab Commander: "Voridus, we can't defeat these Retrievers! We need you to shut down the defenses!"
 * Scarab Commander: "Voridus, the Retriever still attack us! You must deactivate the defenses soon!"

Once the final puzzle is solved, the Sentinel was destroyed and the launch bay disabled for good.

Cutscene

The Scarab approaches High Charity.
 * Voridus: "So you've said many times. I can handle myself, brother. Voridus, out."

The Scarab arrives at the site and firing the main cannon, opening a hole for the Banished to salvage what was inside of it.
 * Voridus: "It's time we got inside to take what is ours!"

Two Banshees arrives at the scene.
 * Voridus: "Go brothers! It's time for us to get our reward!"

Cinematic Cutscene

''A Containment shield around High Charity can be seen from distances on the Ark. Zooming in, the scene moved to a Scarab overwatching Voridus' pack as they gather at the entrance of High Charity while a hole has been made around containment shield by a Scarab earlier. Voridus send a Squad of Jiralhanae to scout inside High Charity in order to search for anything that can be worth taking.''

''Entering High Charity, the Brutes searches anything that can be worth salvaging and something is moving unnoticedly under the darkness. A Jiralhanae heard something and stopped then suddenly a Pod Infector runs to them but killed by Jiralhanae's spiker.''

''Checking the corpses, they laughs but they heard another sound again causing them to go alert once more. The light on the hallway start emitting and the Jiralhanae realize that they are surrounded. One of them was surprised, looking at approaching creature that makes them silent while unnoticedly, dropping the weapons. Sounds can be heard inside High Charity and hearing a scream for help, Voridus turns around wondering what happened inside.''

''A Jiralhanae walks staggerly to outside where Voridus and his pack is. A Jiralhanae is about to approach it but Voridus stop him from getting close. Turns out, a Jiralhanae that went inside earlier has been infected into a Flood Combat Form. Voridus wear his mask and telling his pack to prepare themselves.''
 * Voridus: "Prepare yourselves."

''Preparing themself, the ground shakens as hordes of Pod Infector comes out from High Charity, followed by the screech of the infected Jiralhanae. The Jiralhanae start to fight the Flood but suddenly, an Abomination is rolling past through them and extend it's tentacles, catching a Brute's arm as it struggles. Another Abomination trips it by pulling his legs and Pod Infector start latching to it, beginning to infect.''

''Voridus keep defending himself against Pod Infector and punch an Abomination, stomping it. He then fire one of his weapon to abomination that catches a Warlord, rescuing him and the Warlord immediately charged up the Gravity Hammer and smashed it to the ground while behing, Flood Spawners are coming out from Hih Charity. However an Abomination swiftly catches it's head and pulling him backwards, attempting to take him down.''

''Another Abomination rolls in and went to behind Voridus as it tangle his arm and other Abomination tangle his other arm. With a Warlord finally was taken down and another is struggling to break off from Pod Infector, Voridus switch the blade to the back and backstab the Abomination, throwing the other one to the ground and stomps it. He then quickly slash another Abomination while other Abominations rolls around to find more victims and his units are all struggling as the Flood Spawners and Pod Infector are spreading out from High Charity.''
