Floodgate (Level)

Floodgate is the fifth campaign mission of Halo 3.

Introduction
It takes place in Voi, Africa, Earth during the Second Battle of Earth and is also the first campaign mission where the Flood is encountered.

Upon disabling the Anti-Air Gun in The Storm, a Flood-controlled Covenant cruiser crashes in Voi. In order to eliminate the infestation, Master Chief and the Arbiter must overload the crashed cruiser's engines, wiping out the entire city and the Flood with it.

Upon completing it on the Normal, Heroic, or Legendary difficulties, the player will earn the "Cleansing" achievement and 30 Gamerpoints.

Voi, Africa, Earth Second Battle of Earth

01: It Followed Me Home
 Location : Cliffside Hill

Miranda Keyes (COM): The Flood. It's spreading all over the city.

Lord Hood (COM): How do we contain it?

Miranda Keyes (COM): Find the crashed Flood ship, overload its engine core. We either destroy this city, or risk losing the entire planet.

Lord Hood (COM): Do it.

Miranda Keyes (COM): Chief, make your way to the crash site.

Some time later, when entering the city

The Arbiter: (unintelligible)

Marine Commander (COM): All squads, report!

Marine Sergeant (COM): Multiple contacts, unknown hostiles.

Marine 1 (COM) : There! Over there! We're surrounded, Sergeant!

Flood screams echo in the air

Marine 2 (COM): Aaaaah!

You find a group of Marines in a loading ramp.

Marine Sergeant: Fall back, fall back!

Female Marine: Sergeant, come on!

 Location : Traxus Heavy Industries Factory Complex 09

''Infection Forms and Combat Forms (including the new Brute ones) descend on the Marines, infecting and killing or forcing you to kill them. The female Marine who had spoken earlier is the only survivor.''

Female Marine (upon spotting the Chief): About damn time!

The "Infected Marine" is infested by Flood Infection Forms. N-bCMhBINiA

''The Marine accompanies you into a building, where you run into a lone Marine fighting off a horde of infection forms. It is possible to save him, but more often than not, he will be mutated before your eyes.''

Infected Marine: Uhh! Get off me!

Marine 3: Crikey!

''If you do not save the Marine, the Infection Form dives into the Marine's chest, causing his back to swell and his skin to change color. He collapses to the floor then Whip Tentacles grow out of his right arm and then the sensors on the Infection Form pop out of his chest wound.''

Cortana: I can't tell you everything...it's not safe.

02: Shadow of Intent
SPARTAN-117 and the Arbiter enter the lake bed of Voi where the Scarab was previously fought, and three Elite-controlled CCS-class Battlecruisers fly in formation as the Assault Carrier Shadow of Intent slices overhead from Slipspace, scattering Orbital Insertion Pods.


 * Rtas 'Vadum: Humans, take heed. This is the carrier Shadow of Intent. Clear this sector while we deal with the Flood.

A Major Domo Elite, a few Minor Elites, and some Security Elites leap out of the landed Orbital Insertion Pods ahead of you, fighting against the Flood.


 * Major Domo Elite: High Charity has fallen and become a dreaded hive! A single Flood ship broke our lines and we pursued.


 * Arbiter: But how? We had a fleet of hundreds!


 * Major Domo Elite: Alas brother...the Flood has evolved!

Ending Cutscene
 Location : Crashed Flood-controlled CCS-class Battlecruiser

''Inside the central chamber of the Flood-infested crashed cruiser. SPARTAN-117 releases 'Cortana' from a small Covenant handheld memory unit.''


 * Cortana: Chief!


 * SPARTAN-117: Cortana?


 * Cortana: High Charity, the Prophets' holy city, it's on its way...

''Cortana's projection above the holographic unit flickers and then disappears. Suddenly, the humming of a Phantom's gravitic drives are heard, and a Phantom appears over the open chamber. SPARTAN-117 turns and readies his MA5C ICWS Assault Rifle at it while 343 Guilty Spark floats down from the Phantom, which continues to hover overhead.''


 * 343 Guilty Spark: Reclaimer!

''A Flood Combat Form appears to the right, and 343 Guilty Spark turns and uses a powerful energy beam on it, destroying it in a single glancing hit. 343 Guilty Spark turns back to the Covenant device where Cortana supposedly is, and begins interfacing it with a beam projected from his central eye.''


 * 343 Guilty Spark: We must act quickly before your construct suffers any further damage!

SPARTAN-117 menacingly grabs 343 Guilty Spark and pulls him away from Cortana's storage unit.


 * SPARTAN-117: Wait. Leave. Her. Alone.

343 Guilty Spark continues to project his multicolored energy beam into Cortana's storage unit.


 * 343 Guilty Spark: If we do not take this device to a safe location, somewhere we can make repairs...


 * SPARTAN-117: On Halo, you tried to kill Cortana. You tried to kill me.


 * 343 Guilty Spark: Protocol dictated my response! She had the Activation Index and you were going to destroy my installation. You did destroy my installation. Now, I only have one function: to help you, Reclaimer, as I always should have done.

''SPARTAN-117 stares wordlessly at 343 Guilty Spark, then slightly motions with Cortana's storage device. 343 Guilty Spark takes Cortana's device away, shooting his beam into it, while the Phantom projects a Gravity Lift. 343 Guilty Spark enters it first and SPARTAN-117 reluctantly follows.''

 Location : Voi

''The scene cuts to an aerial one over the whole town of Voi at a high altitude. Clouds completely obscure the surface of Earth, but part of the crashed Flood-controlled battlecruiser is visible in the distance. 343 Guilty Spark flies away from the surface while two CCS-class Battlecruisers of the Sangheilian Fleet "glass" the town of Voi with plasma beams.''

 Location : Portal, Africa, Earth

''The scene cuts to an aerial one above the Forerunner Portal. Its 'wings' are open, and bue energy streams from their tips to the open Slipspace portal drifting ominously above the construct. The scene is quiet, and the moon is in the background. Fighting on Earth has ceased, and the Second Battle of Earth has ended with the departure of the Prophet of Truth's fleet through the Portal hours earlier. Four vessels of the Sangheilian Fleet are gathered above the Portal, and 343 Guilty Spark's Phantom arches to the largest of them: the assault carrier Shadow of Intent.''

 Location : Shadow of Intent, command deck

''Inside the bridge of the Elite-controlled command vessel, the Assault Carrier Shadow of Intent. Elites and humans are gathered around a long holographic table, with Ship Master Rtas 'Vadum floating on a gravity throne at one end with his Elite attendants, SPARTAN-117 and the Arbiter in the middle, and Fleet Admiral Hood and Commander Miranda Keyes at the far side of the table. All are silent except 343 Guilty Spark, who is bobbing at the center of the table and interfacing with Cortana's memory unit with his projector beam.''


 * Rtas 'Vadum: Will it live, Oracle? Can she be saved?


 * 343 Guilty Spark: Uncertain. This storage device has endured considerable trauma. Its matrices are highly unstable.

343 Guilty Spark glances at 'Vadum and Lord Hood


 * Lord Hood: Maybe one of our technicians-


 * Rtas 'Vadum: That will not be necessary.

Coincidentally, the storage device works again, and a holographic projection of Cortana springs up.


 * Cortana: Chief!


 * 343 Guilty Spark: Success!


 * Cortana: ...the Prophets' holy city, High Charity, is on its way to Earth, with an army of Flood. I can't tell you everything. The Gravemind...it knows I'm in the system.

Cortana's image flickers, and SPARTAN-117 turns to the Arbiter and the Elites.


 * SPARTAN-117: It's just a message.


 * Rtas 'Vadum: Let it play.

343 Guilty Spark jolts the device with another beam.


 * Cortana: But he doesn't know about the Portal, where it leads. On the other side, there's a solution; a way to stop the Flood, without firing the remaining Halo rings.

''Suddenly, Cortana's skin lights with lightning and she gasps in sudden pain and collapses onto the 'floor'."


 * Cortana: Ahh! Ahh-ahh-hurry, Chief! The Ark...there isn't much time.

Cortana's recording ends and pauses.


 * 343 Guilty Spark: I'm sorry...


 * Rtas 'Vadum: No matter, Oracle. We've heard enough. Our fight is through the Portal, with the Brutes and the bastard Truth!

Special Operations Elites around the room raise their forearms and roar in agreement.


 * Lord Hood (exhausted): Fine. We'll remain here...hold out as long as we can.


 * Rtas 'Vadum (arrogantly): Did you not here? Your world is doomed. A Flood army, a Gravemind, has united against us! And you can not even survive a small contamination.


 * Lord Hood: And you, Ship Master, just glassed half a continent! Maybe the Flood is not all I should be worried about.


 * Rtas 'Vadum: ...one single Flood spore can destroy an entire species. Would it not have been for the Arbiter's consoul, I would have glassed your entire planet!

Lord Hood angrily motions at 'Vadum, but Miranda Keyes places a hand on his shoulder.


 * Miranda Keyes: Sir, with respect, Cortana has a solution.


 * Lord Hood: Cortana? Did you see her condition? How damaged she is? She could be corrupted for all we know. Her "solution" could be a Flood trap.


 * Miranda Keyes: We should go through the Portal, find out for sure.


 * Lord Hood: What we 'should' do is, Commander, understand that this is humanity's final stand, here, at Earth. If we go, we risk everything; every last man, woman, and child. If we stay, we might just stand a chance.


 * Arbiter: No! If your construct is correct, then the Flood has already won.

''While Hood, Keyes, and the Arbiter argue, SPARTAN-117 bends down and observes Cortana's pained collapsed paused figure. SPARTAN-117 stands and straightens himself.''


 * SPARTAN-117: Sir, I'll find Cortana's solution. Bring it back.


 * Lord Hood: Earth...is all that we have left. Do you trust Cortana that much?


 * SPARTAN-117: Sir. Yes sir.


 * Lord Hood: Chief, this is either the best decision you've made or the worst. Hell, if it is, I doubt I'll live long enough to find out.

Lord Hood turns, looks wordlessly at Miranda Keyes, and then exits the bridge.

 Location : Shadow of Intent, hangar bay

''Inside the Shadow of Intent's hangar bay, both the Elites and the UNSC are readying for battle; the battle through the Portal. While a Phantom drifts into the hangar on the far side, two M12 Warthog LRVs race to the loading elevator, drawing near a group of Marines clustered around some UNSC crates. At uneasy rest opposing the Marines are a Major Domo Elite and a few Minor Elites. The Major Elite's Particle Beam Rifle is resting on the floor. Sergeant Major Johnson, with his arm full with 'stolen' Covenant Carbines brushes past the wordless Elites, scooping to pick up the Major Elite's rifle. The Elites rise in anger around Sergeant Johnson.''

''Nearby, a pair of Orbital Drop Shock Troopers are joking with each other as the Arbiter passes by, with an acquired M41 Rocket Launcher on his shoulder. The ODSTs and a pair of nearby Marines observe the Arbiter in half-awe, half-jealousy over the loss of their Rocket Launcher, when 343 Guilty Spark drifts through the Marines in tow behind the Arbiter, leaving a Marine speechless. Sergeant Major Johnson re-joins the Marines, beginning to hand out Carbines, the scene cuts to the fore of the hangar, where a Pelican Dropship lays before the hangar's energy field.''



''SPARTAN-117 and Miranda Keyes stand at attention before Lord Hood, who looks at them grimly from the rear of the Pelican as the troop bay door shuts and the Pelican takes off. Keyes glances at SPARTAN-117 wordlessly, and the two leave, going off to their own businesses.''

 Location : Portal, Africa, Earth

Hood's Pelican arcs away from the gathered Sangheilian Fleet as the Shadow of Intent powers its engines and thrusts into the Portal, followed by five CCS-class Battlecruisers, and later four more battlecruisers and a pair of UNSC Frigates (not seen).
