The final game in the (first) Halo trilogy, released on September 25, 2007. Picking up directly from Halo 2, Master Chief returns to fight for Earth and discover the secrets of the Forerunners who built the Halos. This game earned $170 million in its first day, breaking all previous records (including Halo 2's.)
The campaign was no longer split into two perspectives like in Halo 2, instead having a single campaign revolving around the Master Chief and the Arbiter working side by side, with the latter only playable in co-op mode (which for the first time in the series could support four players, with players three and four taking on the role of two new Elites created specifically for co-op). The story wrapped up the original trilogy and shows the conclusion of the Human-Covenant war.
The gameplay was kept largely intact and identical to the previous games, only refining the changes made in Halo 2. The only real new features are the weapon types (a complete subset of Brute weapons and two additional grenade types to the standard frag and plasma, spike and incendiary), deployable equipment that change the battle dynamics (impenetrable "bubble shield," trip mine, radar jammer, etc.), and Forge Mode (a map editor which allows the player to create customized multiplayer maps and gametypes).
Though Interquel Halo 3: ODST (which, despite the title, takes place concurrently with Halo 2) and Prequel Halo: Reach were the next two Halo shooters to be released, Halo 4 is the next chronological game in the series, showing the aftermath of the war, the continued development of the UNSC and its Spartan program, and further revelations about the Forerunners.
On October 16 2013 until October 31, Halo 3 was offered as a free-to-own download for Xbox Live Gold customers. 10 years after release, the original version was announced to be backwards compatible for Xbox One.
Halo 3 provides examples of:
- Arc Words: "Were it so easy", which the Arbiter says at both the beginning and end of the game.
- A God Am I:
"My feet tread the path... I shall become a God!"
- Truth has fallen into this hard.
- The Gravemind apparently had delusions of godhood as well. Though in its case, they might not actually be delusions at all.
- After the End: This game kicks off just as the Covenant have killed most of humanity, with the Flood getting ready to do the same.
- Alien Sky: Once you get to the Ark, the sky features an entire galaxy (ours, in fact). Go ahead. Take a moment to stare at it.
- Apocalyptic Log: The terminals on "The Ark", "The Covenant", and "Halo" levels provide a detailed account of the final stages of Flood-Forerunner war. The fall of the Forerunner empire is hastened by the defection of the military AI Mendicant Bias to the Flood. Mendicant, having grown rampant over time, comes to the view that the Forerunners have imposed an artificial constraint on biological evolution via their belief in the "Mantle" and as such must be eliminated. The Forerunners commission a second AI, Offensive Bias, and charge it with stopping Mendicant and the Flood at any cost. The Flood launch a final and utterly massive assault against the Ark (defended by Offensive Bias and the remnants of Forerunner navy) in an attempt to prevent the activation of the Halo arrays. They are unsuccessful, and are defeated at the cost of all the unindexed sentient life in the galaxy, including most of the remaining Forerunners. Offensive Bias manages to salvage Mendicant's personality from the debris of the battle and imprisons it in the Ark's computer systems.
- The Atoner: A hundred millennia after its defeat at the hands of Offensive Bias, Mendicant Bias (via the terminals on the Ark) contacts the Master Chief and expresses a desire to atone for its role in the genocide of the Forerunners.
- Back-to-Back Badasses: Master Chief and Arbiter pull this near the end of the game.
- Badass Boast:
Elite: Brute ships, staggered line! Ship Master! They outnumber us three-to-one!Rtas 'Vadum: Then it is an even fight.
- By Shipmaster Rtas 'Vadum:
Gravemind: Did you think me defeated?!
- By the Gravemind:
- Bash Brothers: The Chief and Arbiter are paired off with one another in much of single-player and for the entirety of co-op.
- Big Bad Ensemble: For at least two thirds of the game, the Prophet of Truth. After his death, the Gravemind assumes the role for the rest of the game.
- Big Damn Heroes: Twice. First the Elite fleet comes to Earth's aid during the Flood invasion, and later Johnson comes to the aid of Chief in the finale against Guilty Spark.
- Bittersweet Ending: Truth is killed, the Covenant falls, the Flood are destroyed at the Ark, and the war is over, but Master Chief and Cortana are lost in space in the back half of the Forward Unto Dawn with no way to get home, and the Chief is forced to go into cryogenic stasis to stay alive. Also, Johnson, Miranda Keyes, and many more are dead.
- Book Ends:
- "Were it so easy." The first time, before the first level begins, it's said by the Arbiter as a response to Sergeant Johnson telling him and the Master Chief not to kill each other. The second time, at the end of the game, it's said by the Arbiter again, as a response to Lord Hood's statement: "It's hard to believe [the Master Chief] is dead."
- Halo: Combat Evolved opened with Master Chief being thawed from cryo-sleep. Halo 3 ends with him going back into cryo-sleep.
- Combat Evolved had Cortana say "keep your head down! There are two of us in here now, remember?". In Halo 3, once you re-unite, she says to "Remember to keep your head down..."
- Both the first and third games end with Chief riding a Warthog to escape an exploding Halo. The same Halo in fact.
- Boss Battle: Scarabs, of the Colossus Climb variety. They're bosses in this game (and ODST) only, since they were more of a scripted event in 2 (and an indestructible hazard in Halo: Reach). There's also 343 Guilty Spark, though the fight against him is intentionally anti-climactic.
- Call-Back: Escaping an exploding station in a Warthog, just like in Combat Evolved.
- Catastrophic Countdown: After starting up the Halo ring, it needs several minutes to charge and literally shakes itself apart. The last section of the game is a mad dash to find a way off. While there's no explicit timer the structural plates fall off at a constant rate.
- Colossus Climb: This is generally how Scarab fights play out.
- Continuity Nod:
- Nearly everything Cortana says in her cryptic remarks during the game are near exact quotes of lines in Halo: The Fall of Reach, which was the jumping point for the entire Expanded Universe.
- When Truth activates the Halo rings, the fourth of the seven rings (representing the Halos) does not light up. Installation 04 was the one blown up in the first game.
- Much of the final level, "Halo", resembles the level "Assault on the Control Room" from the first game, since the level takes place near the control room on a replica of the first Halo.
- Co-Op Multiplayer: Not only was Halo 3 one of the first console games to include online co-op, but it also had a campaign mode where players could earn points from killing enemies and compete against each other to earn the most. Basically, Competitive Cooperative Multiplayer.
- Unlike most Halo games, all four co-op characters are different. 1st player is the Chief, 2nd player is the Arbiter (in single-player, he's a friendly NPC who is present in most levels), and the 3rd and 4th players are two unique Elites with absolutely no plot relevance or even lines (that said, they actually do have canon personalities, though not anything elaborated on in-game; one is a hardened veteran, and the other is a young rookie with a lot of respect for humans). Halo: Hunters in the Dark confirms that the last two did canonically fight alongside the Chief and Arbiter, though not for the entirety of the game.
- Charged Attack:
- The Spartan Laser takes about 3 seconds to fire, but destroys everything that it touches and has sniper-grade range. Careful though, it'll go through your units, too (although a tank and scenery can stop it).
- The Plasma Pistol, which can now stun vehicles.
- Cyber Cyclops: Brute Stalkers, the Replacement Mooks for the Stealth Elites from the first two games, have this look going on with their helmets. Though you probably wouldn't notice, due to the fact that (a) they're invisible most of the time you fight them, and (b) they only appear in two places throughout the entire campaign. Bonus points though for the eye itself being red.
- Damn You, Muscle Memory!: Many people in this game's beta ended blowing themselves up with a mine after attempting to reload their weapons, after being used for so long with pressing X. In more hilarious cases, they deployed mines below Warthogs.
- Dead Character Walking: If you're very careful, follow a set of specific actions, have a lot of patience, and a good dose of luck, it's possible to save Sergeant Johnson.
- Difficult, but Awesome: The Spike grenades appear to be weaker versions of the plasma grenades, until you learn that their explosive pattern is conical from the place of impact. They're meant to be stuck on walls and around corners you can fill a hallway with deadly spikes that can kill from upwards of 40 feet away.
- Does This Remind You of Anything?: When the Chief finally rescues Cortana, the Gravemind's Mind Rape has left her lying on the "floor" of the holo-projector looking ashamed and broken. Just like a real rape victim.
- Enemy Mine: The humans and Elites (and temporarily the Flood) against the Covenant.
- Darker and Edgier: The first two games largely avoided the implications of just how many had died/were dying in the Covenant War, but this game has Earth After the End and takes an Anyone Can Die approach to the main characters.
- Dual Boss: The two Scarabs in "The Covenant".
- Duel to the Death: Brute society relishes in the chances to defend their honor in duels to the death. In the level "The Ark", a Brute Chieftain challenges the Master Chief to have one with him, with even the formality of having all his Mooks standing in a semi-circle to watch you two fight. Guess who wins.
- Enemy Chatter: Both the Brutes and Grunts will talk your ears off in oft-hilarious ways.Grunt: You big bully!
- Fire-Forged Friends: The Chief and the Arbiter throughout the game.
- There are multiple hints towards the rebuilt Alpha Halo, including Guilty Spark's curious "Oh my!" when first accessing the Ark's computer systems and the control room showing Ring 4 as incomplete (but not utterly destroyed, as it was after Halo: CE).
- Guilty Spark zapping one of the marines on the level "The Ark" could foreshadow him killing Johnson.
- Guns Are Worthless: On Easy at least, hitting enemies with your gun often seems to do more damage than shooting them.
- Ham-to-Ham Combat: A three-way between Truth, Gravemind, and the Arbiter.
- I Like Those Odds: See Badass Boast above.
- Infernal Retaliation: When a Brute Chieftain's charging at you, roaring, and brandishing a gravity hammer, you might think of hitting them with a firebomb, as it does a lot of damage. Unfortunately, Chieftains have equipment that renders them temporarily invincible, so when they activate it, they're now charging at you, roaring, brandishing a gravity hammer, on fire, and invulnerable.
- In the Back: How the Prophet of Truth kills Miranda Keyes, by shooting several Spiker rounds into her. And how the Arbiter kills Truth, by impaling him with an energy sword.
- It Has Been an Honor:Cortana: If we don't make it...Master Chief: We'll make it.Cortana: It's been an honor serving with you, John.
- Which itself is a Call-Back to the first game, when returning to the Pillar of Autumn in a captured, damaged Banshee.
- It is also worth pointing out that this is the first time in the games proper that anyone uses the Chief's given name.
- Large Ham: Even more rampant than in Halo 2, with Sgt. Johnson, the Shipmaster, Gravemind and a hammy Prophet of Truth. The latter two even engage in Ham-to-Ham Combat during the first climax.
- Last Stand: The level "The Covenant" is the Covenant's Last Stand against humanity and the Elites. As such, both sides throw everything they have at each other, and it is the longest level of the original trilogy.
- Level in Reverse: "Floodgate" and "The Storm" are reverses of each other.
- Ms. Fanservice : Cortana, as usual.
- Dual-wielding was disabled for the Needler, and its magazine size was decreased. The needles were also changed to do all of their damage right when they hit a player (rather than doing most of it when they shattered), travel faster, and require one less hit for a supercombine.
- Dual-wielding itself was also nerfed; weapons will individually deal less damage when they're being duel-wielded. This is especially apparent with the Magnum; dual-wielded Magnums take almost twice as many shots to kill as one on its own.
- Mythology Gag:
"Your destruction is the will of the gods! And I? I am their instrument!"
- Truth's speech in the second level ends with a quote from the first game's E3 2000 trailer, albeit altered to relate to Truth instead of the entire Covenant.
- Some of Cortana's "crazy" messages are quotes from The Cortana Letters (itself a kind of Production Foreshadowing predating the official announcement of the original Halo: Combat Evolved'). Additionally, many of these messages on the level "Cortana" reference the events of Halo: The Fall of Reach'' (see the nightmare fuel page for details).
- Never Found the Body: Master Chief. The rest of the UNSC assumes he's dead.
- Outrun the Fireball: Blowing up Halo. Escaping Halo. Again.
- Parrying Bullets: From this game onward, it is possible to deflect rockets, either with precise (read: lucky) explosions from grenades or other rockets, or with precise swings from the gravity hammer.
- Pre-Mortem One-Liner: During Truth's death:The Prophet of Truth: I AM TRUTH! The voice of the COVENANT!Arbiter: And so, you must be silenced.
- Red Eyes, Take Warning: 343 Guilty Spark, oh so much.
- Reverse Escort Mission: In the final assault on Truth's sanctum, Master Chief is being escorted by waves of Flood. Unfortunately for you, they will attack you after Truth dies. In addition, they are numerous.
- Rocketless Reentry: Chief has to make an impromptu evacuation from Truth's ship. He leaps out and falls from low orbit, using a door as a drag shield, and lands stunned for some hours, but still alive. Johnson finds him and lampshades Chief's tendency to keep doing this.Johnson: Crazy fool, why do you always jump? One of these days you're gonna land on something as stubborn as you are!
- Scenery Porn: Have a look around some of the outdoor levels, if you aren't too busy staying alive.
- Sequel Escalation: In the previous game, the only time you fight against a Scarab walker is in the "Outskirts" level, and the Scarab itself was basically a piece of 100% scripted walking scenery that was indestructible during gameplay, with the Chief blowing it up in a cutscene. Come 3, you fight against Scarabs far more frequently, and they've been modified to be actual enemies with actual AI that you'll need to take out during actual gameplay (options include using a Scorpion tank or being a one-man boarding party); at one point, you even fight two at once.
- Several to Marathon:
- One of the bonus armor types was developed at a place called Lister, Aigburth on the colony of Ganymede (the very same one that's a moon of Jupiter).
- Also, the Hayabusa armor, which was added as a tribute to Team Ninja putting a Spartan in Dead or Alive 4's roster.
- Shut Up, Hannibal!:Prophet of Truth: I am Truth! The voice....of the Covenant!Arbiter: And so, you must be silenced.
- This Cannot Be!: Guilty Spark upon learning you still intend to fire Halo even after learning that doing so will destroy it:343 Guilty Spark: UNACCEPTABLE! UNACCEPTABLE! ABSOLUTELY UNACCEPTABLE! Protocol dictates action! I see now that helping you was wrong! You are a child of my makers, inheritors of all they left behind. You are Forerunner, but this ring... is mine!
- Tyrannicide: Truth is summarily executed by the Arbiter towards the climax in order to cement the Covenant's defeat.
- The Unfought: Truth and Gravemind.
- Upgrade vs. Prototype Fight: The Terminals reveal that the Forerunners built an AI called Mendicant Bias to defeat the Flood, but he went rogue. To counter him, another AI was built called Offensive Bias, as his successor. Offensive wins, but only because he was stalling for the Forerunners to fire the Halos that thus destroyed every organic being in the galaxy, robbing Mendicant's fleet of its crew.
- Villainous Breakdown: Truth, Gravemind, and Guilty Spark all end up with this. Spark's crackdown is the scariest one.
- The War Sequence: The battle outside the array in the level "The Covenant". It is the final major land battle in the Human-Covenant war, and the Covenant throw everything they have left at you, with the crew of Forward Unto Dawn doing likewise. Appropriately, it has more total forces and more variety of vehicles than virtually any previous battle in the series. The music "One Final Effort" plays, the battle begins, and then the Covenant send two Scarabs against you.
- Why Don't Ya Just Shoot Him?: When Miranda storms the Ark's control room, Truth's Brute bodyguards are seemingly too dumbfounded to just shoot her. Averted by Truth himself, who simply kills her with a Spiker.
- Your Princess Is in Another Castle: At the end of the game, you drive a Warthog across an exploding landscape covered in enemies. Then your HUD shows 500 metres to go to a waypoint. Nearly made it! Then you make it to the waypoint, and another countdown starts...note
- Zerg Rush: According to the terminals, the Flood and Mendicant Bias assaulted the Ark and its Forerunner defenders with nearly five million assimilated spacecraft (comprised mostly of unarmed civilian vessels used as cannon fodder) in order to stop the Halo arrays from being fired.
