x360a.org :: Halo 4 Achievement Guide & Roadmap

Introduction
Halo 4 is the eighth installment of the Halo franchise and is the first of the new "Reclaimer Trilogy" created by 343 Industries. It has been four years since John went into cryosleep (Halo 3). Awoken and ready to fight, John and Cortana must uncover the many secrets & technology the ancient forerunner planet "Requiem" holds.

The Campaign achievements are straight forward and as always, Mission Select is available. There are 7 Terminals you must find and access and skulls are available for use right from the start. A Xbox LIVE Gold Account is required for the Multiplayer and the new gametypes Spartan Ops and War Games. Each week a new Chapter/Episode for Spartan Ops will be available to download.


Installation
Halo 4 is shipped with 2 discs. The second disc must be installed (4GB) in order to play the Multiplayer.
Insert Disc 2, launch the game and follow the instructions. Upon completion, eject the disc and insert Disc 1. You no longer have need for Disc 2.

Campaign Co-op Playthrough on Heroic 12 for 190
This playthrough will be done Cooperatively with another player (Online or Local) on Heroic to specifically unlock Bromageddon and Bropocalypse. You may choose to play on Legendary to also unlock The Legend of 117 but you will naturally unlock this during your Solo Legendary Playthrough. See The Legend of 117 for tips if you choose Legendary for this playthrough.

Halo 4 allows up to 4 players playing Co-op at a time. Find partners/buddies in the Achievement Trading Thread.


Campaign Terminals, Skulls, & Mission Specifics 11 for 235
Upon completion of the Campaign you are able to replay every Mission on any Difficulty. Choose a Mission and set the difficulty to Easy unless specified otherwise.

• Terminals - There are a total of 7 Terminals you must find/access. Please see Terminus achievement description for Terminal locations. Find one for Contact the Domain, and find all for Terminus.

• Skulls - Skulls are available and unlocked right from the start. You do not have to seek them out in Halo 4. Silver Skulls are recommended to activate because you must complete a level on Heroic whilst 3 are activated for Skullduggery. This can be done Cooperatively.

• Mission Specifics - There are 8 Mission Specifics to unlock (ie Digging up the Past, Midnight Launch...) These can be missed during your first playthrough. After you've completed your initial playthrough, load up each Mission and achieve the required Mission Specific task then Save and quit.

Campaign Solo Playthrough on Legendary 2 for 160
This playthrough will be done Solo on Legendary. You cannot do any part of this playthrough with another player either Online or Locally. Sucessful completion of this difficult playthough unlocks Lone Wolf Legend and The Legend of 117.

See the Roadmap item Difficulties for extra info. See the Guide achievement description for Lone Wolf Legend for tips.


Infinity (Multiplayer) 15 for 160
The Infinity consists of Spartan Ops and War Games. You will have the option to customize your Spartan IV within the Infinity. Your Spartan IV Ranks up from the points you earn in both game modes.

• War Games - Competitive Halo Multiplayer gameplay.
• Spartan Ops - New Co-op Multiplayer Episodic game mode.

Infinity :: Spartan Ops 9 for 255
This is a 10 week long Episodic game mode that takes place chronologically 6 months after the events of Halo 4. Spartan Ops allows up to 4 player co-op & you have the option of matchmaking if you are solo. The first 5 Episodes have achievements.

Each week on Mondays at 6 am (Eastern US, GMT -5) there will be a FREE streaming Spartan Ops Episode available to watch, followed by 5 Chapters of gameplay. Please see the Infinity :: Spartan Ops Info and Discussion thread for more info as to when new Episodes are available and which achievements are currently obtainable.

Difficulties
The difficulties are Easy, Normal, Heroic, Legendary and the achievements are stackable, meaning unlocking The Legend of 117 unlocks Wake up John and I Need a Hero.

On Easy difficulty, it is possible to unlock the 'Completed Mission...' achievements (Dawn, Requiem, Forerunner, ...) but you will not unlock a 'Completed the Campaign...' achievement on Easy.

Changing difficulty to from Heroic to Legendary on Mission 8 in hopes to unlock The Legend of 117 or Lonewolf Legend will NOT work (cheating). In order to unlock a 'Completed the Campaign...' achievement on a specific difficulty you must NOT change the difficulty settings at any point during that entire playthrough.

In order to unlock all the campaign's 'Difficulty' achievements you must complete 2 playthroughs. One Cooperatively on Heroic, and one Solo on Legendary.

A word about playing Co-op and Solo playthroughs at the same time.
"Both solo and co-op playthroughs have their own save data. As long as you reach a checkpoint in solo, making sure to save and quit after, it'll stamp that progress. Start a lobby with a friend, and you'll see 'Start Co-op Campaign'. Modify the options to your liking, start the game then back out. Return to the Campaign menu with no other players, and everything should be as it was on your solo playthrough."

I Need a Hero 40
Completed the Campaign on Heroic or harder.

Campaign related. Online not required. Must be obtained on Heroic+.
Complete the Campaign either Solo or Cooperatively.

To start a Coop Campaign you must invite a friend to join your CAMPAIGN LOBBY/or join their's. In the CAMPAIGN LOBBY press Roster to see a list of available friends to invite. Highlight the one you wish to invite and press then Invite to Party. Then START CAMPAIGN.

In addition to the Solo methods Slow or Fast (See Lone Wolf Legend for method descriptions) you can use a third method - always keep 1 Spartan Safe.

Safe

• Have a partner (or a 2nd controller) hang back while you Rush or clear out an enemy area.
• If and when you die, you will respawn in this Safe area until you defeat the enemies to get to a new Safe checkpoint.
• Have the partner (or a 2nd controller) commit suicide and be transported to your new Safe checkpoint.

The Legend of 117 70
Completed the Campaign on Legendary difficulty.

Campaign related. Online not required. Must be obtained on Legendary.
Complete the Campaign either Solo or Cooperatively.

See Lone Wolf Legend for tips on Legendary difficulty.


Lone Wolf Legend 90
Completed the Campaign solo on Legendary difficulty.

Campaign related. Online not required. Must be obtained on Legendary.
Must complete the Campaign Solo.

There are a couple ways to play this difficulty setting effectively. You can playthrough the levels Slow or Fast.

Slow - Pace yourself and kill every last enemy, get a checkpoint and continue playing this way checkpoint after checkpoint. Spending 45 - 60 minutes per level.

• Use a powerful weapon combo like PP/BR or BR/Sniper. Use the Plasma Pistol charged shot to deplete shields and then switch to your BR to headshot the unshielded enemies. Use the LightRifle/Suppressor combo or LightRifle/Scattershot combo.
• Use a ranged weapon and pick off enemies from afar.
• Shoot at enemies while remaining near cover.
• Revert to cover if shield is even remotely depleted - by the time you realize you've been shot at your shield will most likely be gone.
• Stickies are very powerful, use them often when they are available.
• Save Power weapons for the Hunters, or tough enemies near end of levels.

Fast - Rush the enemy, grab only the weapons/ammo for enemies you must fight. You are looking to get to checkpoints with as little resistance as possible, beating the level under 10 - 15 minutes.

• Use a powerful weapon combo like BR/Shotgun or Sword, BR/Sniper. Use the Shotgun or Sword to take down an enemy quickly while you are rushing past if you are met with too much resistance.
• Find alternate routes that will keep you primarily hidden from enemies.
• Use Ghosts, Banshees, Warthogs for speed and their ability to get you to areas you could not get to by foot.
• Use a ranged weapon and pick off enemies from afar that will kill you as you Rush (Knights, Turrets).
• Use cover when needed but also to remain hidden from enemies walking/running past
• Stickies are very powerful, use them often when they are available.
• Save Power weapons for the Hunters, or tough enemies near end of levels.

You can use both these methods interchangeably, sometimes you will get to a point where you must clear the area of all enemies before moving on. Adopt a method you feel comfortable with.

Halo 4 - All Terminal Locations - Terminus Achievement Guide - YouTube

Timelinks
• 0:06 - Terminal 1 - Mission 2 'Requiem' - Rally Point Bravo
At the end of the level, after defeating 2 hunters, you will come to a long hall. At the end of the hall you will view this terminal in plain sight under a clear ramp that leads to the end.

• 0:35 - Terminal 2 - Mission 3 'Forerunner' - Rally Point Bravo
During the mission, near the beginning, you will defeat a small group of crawlers and a promethean knight outside in an open area, and your HUD will begin to become distorted. Masterchief and Cortana will begin speaking about the signal distortion, and masterchief will say "What's with this distortion?". Once this happens, the terminal should be on ground level, under the next objective.

• 1:05 - Terminal 3 - Mission 4 'Infinity' - Rally Point Bravo
After meeting up with your teammates, there will be a short cutscene and you will spawn inside a ship. Just turn around and the terminal will be directly behind you.

• 1:28 - Terminal 4 - Mission 5 'Reclaimer' - Rally Point Bravo
Midway through the level, after the first main cutscene, you will end up indoors. You will have to pick up Cortana and make your way through a hallway. Instead of boarding the elevator (primary on-screen objective) take a right and the terminal should be there.

• 1:55 - Terminal 5 - Mission 6 'Shutdown' - Rally Point Delta
When progressing through this mission, you will come to a section with a bunch of light bridges. At one point you will reach the end of the path and two hunters will appear. The terminal is directly before this checkpoint, but you can easily backtrack. When going from the entrance to the location of the hunters, take the last possible left and the terminal will be located behind the structure on this platform.

• 2:21 - Terminal 6 - Mission 7 'Composer' - Rally Point Bravo
Once you reach the outdoor part of this level, run across the terrain to the building that says "Atrium" on the side. At the base of that sign is the Terminal. The "Atrium" sign does repeat itself on the side of the building, but this is one the closest and in the most clear sight from where you begin this section.

• 2:59 - Terminal 7 - Mission 8 'Midnight' - Rally Point Bravo
Once you get to the part of the level where you are in foot, progress through the story by clearing the rooms of enemies and moving forward. Once you enter the 3rd or 4th room, you should see the terminal located behind two pillars. Walk around to the back side to access it.

Digging up the Past 20
Found and accessed Chief's record in mission 1.

Campaign Mission 1 'Dawn' specific. Online not required. Can be obtained on Easy+.
Use 'Mission Select' after initial Campaign playthrough if missed.

The Chief's record can be found down a ramp on your left after Cortana uploads herself into the chip that you insert into your helmet.
Press to access it.

Do NOT head into the next room to touch the control panel before finding the record. It glitches the achievement for some reason.

Glitchy: Can be glitchy!
The Fix: Restart the level. Next time don't touch the control panel and it should unlock.

Midnight Launch 20
Got significant air in the Warthog at midnight in mission 2.

Campaign Mission 2 'Requiem' specific. Online not required. Can be obtained on Easy+.
Use 'Mission Select' after initial Campaign playthrough if missed.

Be the driver in a Warthog and achieve significant air when your console time is at 12:00 am. Only the Driver will unlock the achievement. It's been reported that the achievement may take a couple seconds to unlock.

If 12:00 am has passed you can alter the console's time by either methods

• Online - "change your timezone to one that's about to strike midnight so you can stay on LIVE and put a timestamp on the achievement."
• Offline - "set your console's clock to 23:50 (to be safe), then load up Mission 2: Requiem.

"Rush through the start of the mission (no enemies), until you reach the Warthog. Press your 360 Guide Button and wait for the time to hit 12pm (midnight). Drive the Warthog down the dirt track for about 20 seconds until you reach a destroyed pipe. Blast your way through it and at the end you'll hit a jump. If done at the right time, the achievement will unlock during mid-air."

This is my Rifle, This is my Gun 20
Carried a UNSC weapon all the way through mission 3 on Heroic or harder.

Campaign Mission 3 'Forerunner' specific. Online not required. Must be obtained on Heroic+.
Use 'Mission Select' after initial Campaign playthrough if missed.

You start out with 2 UNSC weapons

• Assault Rifle
• Magnum Pistol (recommended)

Pick one of the two to carry with you as your secondary weapon until the Mission ends. It is ok if you run out of Ammo on the UNSC weapon. - It is NOT ok if you drop it - 'Revert to last Save' if you accidentally drop it.

Note: If playing on Heroic Cooperatively, you mustn't die. You will not respawn with a UNSC weapon. Unless your buddy is willing to 'Revert to Last Save' every time one of you die, your best bet is to play this one Solo, or play it Safe if you must play it Co-op.


Bros to the Close 20
Completed mission 4 without one preventable Marine death on Heroic or harder.

Campaign Mission 4 'Infinity' specific. Online not required. Must be obtained on Heroic+.
Use 'Mission Select' to after initial Campaign playthrough if missed.

Easiest if done Cooperatively. There are a total of 6 UNSC Marines that must survive.

2 Marines - join you after your encounter with Commander Laskey.
4 Marines - are fighting Crawlers, Watchers, Knights at the base of a hill.

You can start at 'Rally Point Bravo' if you've completed the level already.
Use ranged weapons when you can to keep a distance between the Marines and the Promethean Crawlers, Knights and Watchers. If your Marines charge forward, try to keep yourself in front of your Marines to keep the enemy fire focused on you. You will want to take out any Promethean Knights, Watcher and Turrets ASAP from afar, they do the most damage vs your Marines. You will find turrets scattered throughout the area thereafter that are helpful when waiting for Cortana to unlock the hatch. Once she unlocks it, retrieve her chip and the achievement will unlock.

Note: If a Marine dies, you are able to 'Revert to Last Save' as much as you please, the achievement will still unlock. If you happen to get a save checkpoint while one is dead, you must restart the level (back to 'Rally Point Bravo')

Mortardom 20
In Mission 5, steal a Wraith and use it to kill at least four enemy Wraiths on Heroic or harder.

Campaign Mission 5 'Reclaimer' specific. Online not required. Must be obtained on Heroic+.
Use 'Mission Select' after initial Campaign playthrough if missed.

The easiest way to steal a Wraith is to kill the gunner from a safe distance, and emp blast it with the charged Plasma Pistol shot (hold and release). While it is temporary disabled, you must go along side it press to steal it. Make sure you are Holding to 'Operate Plasma Cannon'. This will kick out the 'Wraith Operator' and you must shoot him. Then you can Hold along side it to 'Operate Wraith'.
Now use it to destroy 4 other Wraiths. The trick is to keep moving & dodging the enemy Wraith's plasma attack while staying a safe distance from them, especially their short/mid ranged gunner's attack. There are a total of 8 Wraiths in the level.

Give Him the Stick 20
In Mission 7, in solo Campaign, take out both Hunters using only the Sticky Detonator.

Campaign Mission 7 'Composer' specific. Online not required. Can be obtained on Easy+.
Use 'Mission Select' after initial Campaign playthrough if missed.

Kill both Hunters using only the Sticky Detonator while playing Solo.
A Sticky Detonator is acquired in a weapon cabinet in the far left corner in the lab where the two Hunters are wrecking havoc. A second Sticky Detonator is found within the small white room within this lab. It is a remotely detonated weapon. Press to fire a sticky onto a Hunter. The sticky will only explode when you press a second time. You have 5 rounds in the Sticky Detonator, so play this level on Easy because it will take two Sticks to kill each one. Pick up a second round of ammo if you are playing on a higher difficulty.

Chief, Smash! 20
In Mission 8, kill 3 Crawlers in one hit with the Gravity Hammer.

Campaign Mission 8 'Midnight' specific. Online not required. Can be obtained on Easy+.
Use 'Mission Select' after initial Campaign playthrough if missed.

The Hammer is acquired in an armoury room shortly after Rally Point Bravo. Crawlers are the dog looking beasts with orange flame heads. Wait until many traverse the bridge to try to attack you at once, and kill 3 with one swing of the Gravity Hammer. If you wait/survive long enough there will be swarms of them to smash.

Glitchy: Can be glitchy.
The Fix: Just keep at it until it unlocks.

Infinity Multiplayer :: Spartan Ops related. Online Required. Must be obtained on Heroic+.

There are 2 generators you must protect. If you are playing Co-op with 4 players you will spawn with 2 Warthogs at the start of the level. If you are playing Co-op with 2 players, you will spawn with Mantis at the start of the level. Using the Mantis to protect the generators is reported to be the easier method.

Get in the vehicle of your choice and use it to kill the enemies up until you reach the generators. Position your vehicles between or around each generator to protect the one that will be attacked (the side the covenant is dropped off on, that generator is usually attacked). There are also stationary turrets located above each generator if you need extra firepower.

A warthog tactic that works (3+) - Position the Gauss Warthog between the generators.
Have the second Warthog be Spartan driven with 2 marines (one with rockets). Use this Warthog to ambush the Covenant after each time they are dropped off. Your marine with rockets will usually take care of the Phantom's plasma gun, and large groups of Grunts.
Drive back and forth under the bridge and attack the Covenant from behind as they push toward each generator.

Repeat if unsuccessful.

You might want to look at the profile again.

This is great. While I personally am in no rush for the achievements, it's great to see someone who actually posts around the forums regularly, contribute this and not one of the random members who only post videos and ONLY do it so their videos can be used in a guide.

This will come in handy in the next few weeks.

Thanks to all who is apart of it.

God damn, that gets annoying.

Have you had the game since Friday OP, or are you just really quick?

[Teh Phantomz]

Guide is coming along nicely, well done

[JEEP43524]

WoW this is look cool !!!

[XCVii 007]

This'll be a very helpful guide, from what I can already tell.

Hey, I think I have a better video for the achievement: Digging Up the Past. I think you should put this one in its place.

He prob had the guide made before the game even came out. I know I've had mine in a word doc 99% complete since last week since all the achievements are self-explanatory except for the chapter-specific ones and a couple Spartan Ops ones. I just was waiting till midnight MY time to put mine back up since it got taken down and add in all the youtube vids and the last couple descriptions, but seeing as this one is just fine there's no reason to have two on x360a. I'll stick with my walkthrough on TA. Good work OP.

nice guide, it also should be noted that you can't change your pose/stance until you rank up to SR13

[lifeexpectancy]

FYI for midnight launch you can change your clock and still do it ONLINE for the datestamp. Just change your timezone to one that's about to strike midnight so you can stay on live and put a timestamp on the achievement.

Very good guide though in depth and simple.

Edited it. Nope, no skulls to find in the campaign only terminals.
Note that you can't watch the clips in game, you must 'download' them in game to unlock them for viewing in Waypoint. I believe they ran out of disk space.

Cheers!

Nice looking guide, sure it'll come in handy at some point in the not too distant future. I kinda wanna do it legendary solo without any aid for my 1st playthrough, just to say I did it (not sure how hard it'll be yet).

They mentioned a few weeks ago about the terminals being accessed via waypoint only, due to time constraints in including them on disc. Kinda pissed me off a little because 343i did such a good job with anniversary's terminals (would have been nice in months or even years to come to give the game a playthrough to view the terminals & cutscenes.

I'd have liked to have seen Skull collecting included as well, just makes it fun to see how long it goes before someone finds them all, or find the trick to make them appear like H3's rings.

Anyhow thanks fella for the hard work, damn wish my game had come on damned time.

[Burnout x360a]

Excellent guide, nice and simple. Thanks.
