Part 01: The Library

343 GUILTY SPARK:

We must collect the Index before we can activate the installation.

(Over the course of the level, 343 Guilty Spark mutters all sorts of random phrases. Here are most, if not all of them)

1. Huaaaaa, huaaaauuuuhummmmm.
2. Ahhhh...I, am a genius. Heeheeheehee!
3. Ah.
4. Oh. Hello.
5. Hadaadeeeeiiiii, hadadummm.
6. Hmmmhummmm, hahummmhmmm. Hmmmhu-umhaummmm.
7. Hahahahaha!
8. Laaaa, dadadadadaaaauuuuhhh.
9. Oh, that's a good idea!

(When you reach one of the rotating doors)

343 GUILTY SPARK:

We are near the Index chamber. Follow me.

(When you emerge into the large central chamber)

343 GUILTY SPARK:

The energy field above us contains the Index. We must get up there.

(When you come to a huge door, which is locked)

343 GUILTY SPARK:

The security doors have sealed automatically. I will go access the override to open them.

(When 343 GS returns)

343 GUILTY SPARK:

Please, follow closely. This portal is the first of ten.

(As you move into the next hallway)

343 GUILTY SPARK:

Puzzling. You brought such ineffective weapons to combat the Flood, despite the containment protocols.

(Moving down another hallway)

343 GUILTY SPARK:

The Flood must not escape the installation. They would consume all.

(Another hallway)

343 GUILTY SPARK:

You can see how the body's been transformed by the genetic restructuring of the Flood infection. The small creatures carry spores that cause a host to mutate. The mutated host then produces spores that can pass the Flood to others. It is insidious and elegant. As long as any hosts remain, the Flood is virulent.

(Going down yet another hallway)

343 GUILTY SPARK:

We must continue. This way please.

(Further down the same hallway, just before you're jumped for the first time from all sides)

343 GUILTY SPARK:

This installation's research facilities are most impressive! Perhaps we'll have time to see them later.

(As 343 GS sends a squad of Sentinels to assist you)

343 GUILTY SPARK:

These Sentinels will supplement your combat system. But, I suggest you upgrade to at least a Class Twelve combat skin. Your current model only scans as a Class Two, which is ill suited for this kind of work.

(As you near the first platform lift)

343 GUILTY SPARK:

Pardon me. A plasma conduit breach in section 5-5-2-4 has disrupted power flow to a gravitic maintenance assembly. Repairs require my attention. I will return soon.

(As you ride the first lift)

Part 02: Wait, It Gets Worse!

(A little bit down the first hall of the second floor)

343 GUILTY SPARK:

Flood activity has caused a failure in a drone control subsystem. I must reset the backup unit. Continue on. I will rejoin you when I have completed my task.

(Another hallway)

343 GUILTY SPARK:

The Sentinels can use their weapons to manage the Flood only for a short time. Speed is of the essence.

(Another locked door)

343 GUILTY SPARK:

Please wait here.

(Hallway)

343 GUILTY SPARK:

Your environment suit should serve you well when the Flood begins to alter the atmosphere. You are a good planner.

(Hallway)

343 GUILTY SPARK:

The installation was well conceived. It is surely the only way to end the Flood threat.

(As you ride the second platform lift)

Part 03: But I Don't Want To Ride The Elevator!

(Hallway)

343 GUILTY SPARK:

I would conjecture that the other species currently on the installation is responsible for releasing the Flood. They seem most persistant in their attempts to access restricted areas.

(In a large, open, cavernous hallway)

343 GUILTY SPARK:

Why naturally the Flood is simply too dangerous to release, and mass sterilization protocols may again need to be enacted. Of course, samples were kept here after the last catastrophic outbreak...for study. It seems... that decision may have been an error.

(Another hallway)

343 GUILTY SPARK:

The installation was specifically built to study and contain the Flood. Their survival as a race was dependent upon it. I am grateful to see that some of them survived to reproduce.

(Coming to ANOTHER locked door)

343 GUILTY SPARK:

I will deactivate the security lock. Wait here.

(ANOTHER hallway)

343 GUILTY SPARK:

Please stay close. Time is short.

(Another platform lift)

Part 04: Fourth Floor: Tools, Guns, Keys To Super Weapons

(What is this? A hallway?!?!)

343 GUILTY SPARK:

The Flood are already hard at work repairing your vessel. Its parasitic nature belies the Flood's intelligence.

(Final cinematic, when you cross a small bridge onto a bizzare, cluttered platform which quickly begins to descend)

343 GUILTY SPARK:

The energy barrier surrounding the Index will deactivate when we reach the ground floor.

(When the platform comes to a stop)

343 GUILTY SPARK:

You may now retrieve the Index.

(The Chief walks slowly over to the Index, which is held in a sheath of some sort. Sections of the sheath move in and out for a few moments, before the Index itself pops slightly out of the top of the sheath. The Chief removes it and stares at it for a moment, before 343 Guilty Spark zaps it from the Chief's hands and into some sort of transdimensional pocket)

343 GUILTY SPARK:

Protocol requires that I take possession of the Index for transport. Your oganic form renders you vulnerable to infection. The Index must not fall into the hands of the Flood, before we reach the Control Room and activate the installation.

(343 GS and the Master Chief teleport away from the platform)

343 GUILTY SPARK:

The Flood is spreading! We must hurry!
