Halo Infinite Achievement Guide (Campaign)

Welcome to the Achievement guide for Halo Infinite’s campaign! The list as a whole is pretty obtainable. The majority of this list is divided up into story Achievements, collectible related Achievements and your standard open world completion Achievements. The end of the list is made up of a few miscellaneous Achievements.

Depending on your skill for your LASO run, this is a very obtainable list from top to bottom.

It is going to take multiple play throughs in order to complete. You will need to find all of the Skulls before you can activate them for your LASO run. Everything except the difficulty specific Achievements can be done on any difficulty you want and turning Skulls on does not disable Achievements.

Missables

Unfortunately, there are some missable Achievements. There is no chapter or mission select at the time of launch. So if you miss something, you’re going to need to play through again or wait for the game to updated with a mission select feature. A feature that has been confirmed to be coming eventually.

Luckily, there’s not a whole that can be missed. There are some collectibles that can be missed. The collectibles in the very beginning of the game before you enter the open world can be missed. When you exit the structure, it will be locked behind you. Fortunately, your collectibles will carry over across multiple play throughs.

Glitched Achievements…Kinda

The Achievements in Halo Infinite can sometimes glitch on you. However, all hope is not lost! If you complete an Achievement and it doesn’t pop, don’t worry. It will eventually pop as you continue to play. I had this happen to me several times. They will all pop over time. This has even been confirmed by the dev team.

Multiplayer

As you most likely know, the multiplayer portion of Halo Infinite was released a few weeks early. If you’re looking for those Achievements, they can be found in a multiplayer only Achievement guide. The link is below.

Headmaster Headmaster

Complete all main missions on Legendary with all Skulls active.

Before you can attempt this, you will need to first collect all of the Skulls in a separate play through. Once you have them all, you will need to activate every single one of them and then complete the main campaign on Legendary.

For uninitiated, this is referred to as a LASO (Legendary All Skulls On) run.

Skulls found in Halo Infinite:

  • Bandana – Unlimited weapon ammo, grenades and no cooldown timer for your abilities.
  • Black Eye – Your Shield will only recharge when you melee an enemy.
  • Blind – No HUD.
  • Boom – Explosion radius is doubled.
  • Catch – Enemies will throw and drop more grenades when killed.
  • Cowbell – Acceleration speed from explosions is increased.
  • Famine – Weapons dropped by enemies will only have half as much ammo. This is will not be a problem as the Bandanna Skull gives you infinite ammo.
  • Fog –  Motion tracker is disabled.
  • Grunt Birthday Party –  Headshots on Grunts will throw out some confetti.
  • IWHBYD – You will hear rare dialog from enemies more commonly.
  • Mythic – Enemies will have more health.
  • Thunderstorm – Ranks up enemies.

The LASO run in Halo Infinite comes in a little easier than in previous Halo games as the Iron Skull is not in Halo Infinite. It will also benefit you that the Bandanna Skull is required which gives you infinite ammo.

Here are some general tips to make things as easy on yourself as possible.

  • If you do this over multiple sessions, do not select “Continue” from the main menu. Instead, you’re going to want to select “Load” and load your LASO playthrough that way. Selecting “Continue” can actually turn off the Skulls.
  • You will have no HUD, so you won’t know when you’ve gotten a checkpoint. The thing about checkpoints is that you can only get them when you have a full shield.
  • So, to ensure you will receive a checkpoint, you should take out all of the enemies except for one. Make sure to leave something weak for last like a Grunt. Melee the last Grunt to recharge your shield and receive a checkpoint. This is very important because it is possible to lose hours worth of play time if you die.
  • With no HUD, you won’t be able to see what grenade or ability you have equipped. Below are the button combinations for each one.
    • Abilities
      • Grappleshot – cn_right, cn_right
      • Threat Sensor – cn_right, cn_down
      • Drop Wall – cn_right, cn_left
      • Thrusters cn_right, cn_up
    • Grenades
      • Frag – cn_left, cn_left
      • Plasma – cn_left, cn_up
      • Spike – cn_left, cn_down
      • Dynamo – cn_left, cn_right
  • You can take a Scorpion gun with you through the entire game. This is a very powerful weapon that will make quick work of enemies even on Legendary.
    • The Scorpion gun can only be picked up when you’re in Outpost Tremonius at the beginning of the game. Pick this up before entering the Pelican. Once you leave, the weapon will be gone for good.
    • After clearing out the enemies here, look to the northeast to see an AA gun and a some wreckage. Grapple up there and you will find a dead UNSC marine and a data pad. Interact with the data pad and then get on top of the right AA canon. You’ll then be given a prompt to pick up the weapon. Pick it up and board the Pelican to progress the story.
    • It’s important to note that if you drop this weapon at any point during the game, it will completely disappear for good. You will not be able to pick it back up. Because of that, you need to be very careful when using your Grappleshot. You don’t want to accidentally shoot a weapon with the Grappleshot. This will automatically replace the one you have with the one you shot. Also, be careful when interacting with consoles. You may accidentally pick up a weapon if it is too close to a console.
    • If you do accidentally drop it, you can quit the game and then reload your most recent checkpoint.
    • There is also no splash damage from the Scorpion gun, so there’s no need to worry about that.
  • The Grappleshot + Plasma Sword is a very powerful combination to take advantage of. Shoot an enemy with the Grappleshot and then hit them with the sword. This will also count as a melee which will replenish your shield.
  • You can spam your gear as there is no cooldown time due to the Bandanna Skull.
  • Spamming the Threat Sensor will help you locate enemies.
  • Collect what Spartan Cores you can to upgrade your Grappleshot to the point where it can stun enemies. You should also upgrade your Energy Shield.
  • Keep your distance in firefights. There’s a lot of space on Zeta Halo, make sure to take advantage of it.

Spartan Cores are found across the map. Spartan Core locations will be revealed on the map when you capture FOBs.

All you have to do here is go to each of the red icons and kill the marked target and other enemies. As you approach the area where a target is, they will automatically be marked. They will have a health bar above them. Once you kill them, the activity won’t be complete until you also kill the rest of the enemies that are found at the marked location.

Audio Logs are exactly what you think when you hear the term.

The Audio Logs are the only collectible that do not show up on your map. These are usually found at FOBs, Banished Outposts, main story missions and other marked locations. A majority of them will be found at these marked locations, but there are still some that are found in the open world of Zeta Halo.

Gun Runner Gun Runner

Take down all three Banished AA guns in under 20 minutes.

As you progress through the story, you will eventually be shot down. You will then have three objective markers that take you to the three AA guns that you need to destroy.

These are the AA guns that you will need to destroy in 20 minutes or less.

There is a little bit of leeway here as the timer wont start until you destroy the first AA gun. So, you basically have 20 minutes to destroy the other two. Get to each one as quickly as you can. Skip the enemies on the way to each one and destroy them as quick as you can.

Spam your Grappleshot to traverse and dodge enemies quickly. Two of the of the AA gun locations will require you to interact with a console in order to activate the gravity lift. You can press cn_down to scan for their location. It will show up highlighted as yellow. Put down a Drop Wall before interacting with the console. You don’t want to take too much damage and die. Outside of using the Drop Walls to turn on the gravity lifts, make sure to throw one down if you’ve taken too much damage on your way to the locations and need to take cover and replenish your shield.


Forza Veloce Forza Veloce

Complete all 14 main missions in under eight hours.

I know speed run Achievements can be stressful, but that won’t be the case here.

For this, you’re going to want to only focus on completing the story missions. Those will always be the yellow objective markers on your map. You’re going to want to skip the side objectives with the exception of some FOBs.

You can quickly capture an FOB if it’s on your path to whatever story objective you’re headed to. These are small, so they can be captured rather quickly. These act as fast travel points, so that will help you cut down on travel time. Just don’t go too far out of your way for them. Like previously mentioned, if there is one on the path that you’re traveling, quickly capture it.

You can also play on any difficulty. So, you can switch this to easy to make things much easier on you. You can also use Skulls. They will not void this Achievement.

Eight hours is a pretty generous time limit. It’s way more than enough especially if you’re playing on easy and/or using Skulls.


Passing the Gas Passing the Gas

Kill a Grunt that’s been thrown by a Brute.

Every so often in enemy encounters, there will be suicide Grunts that area holding two live plasma grenades. If you’re too close, they’ll run toward you and explode. So, when you see them. back up and get some distance from them. If there is a Brute in the enemy group, they’ll pick up the suicidal Grunt and throw it at you.

In order to earn this, you need to kill the Grunt that the Brute throws at you.

I was able to get this at the Bluebell Squad icon. A ship drops off a suicidal Grunt and Brute when defending the squad.


Nosebleed Nosebleed

Check out the best possible view.

In order to earn this, you’re going to reach the highest point on Zeta Halo. This is a mountain that can be accessed when your story objective is “Investigate the Banished Dig Site.” This mountain on the western side of the area.

There is actually a side mission on this mountain called “Foxhound Squad.” The Achievement point is just a little bit higher than Foxhound. Keep climbing until this pops.


Those Wonderful Toys Those Wonderful Toys

Successfully use the Grappleshot 50 times.

You will begin the game with the Grappleshot in your inventory. All you have to do is press cn_RB in order to use it. As long as the wire doesn’t break when shot, it’ll count as a use.

There will be a short cooldown time after using it, but this can be earned very quickly in the first mission if you’d like to get it out of the way early.

When you have other gear later in the game, you will need to press cn_right and then cn_right again to equip it if you have something else equipped.


Aegis Fate Aegis Fate

Deploy the Drop Wall 50 times.

You will be given the Drop Wall as part of the story during Connections when inside of the Conservatory.

Press cn_right and then cn_left to select the Drop Wall. Press cn_RB to use it. This deploy a small shield in front of you to give you some cover.


All-Seeing I All-Seeing I

Use the Threat Sensor 50 times.

You will be given the Threat Sensor as part of the story during Lockdown when inside of the Tower.

Press cn_right and then cn_down to select it. Press cn_RB to use it. This will reveal any enemies if they are inside of the Threat Sensor radius.


Run Rabbit, Run Run Rabbit, Run

Use the Thruster 50 times.

You will be given the Thruster ability as part of the story during Connections when inside of the Conservatory.

Press cn_right and then cn_up to select it. Press cn_RB to use it. You’ll be able to boost in whatever direction you’re going when using it.


Whip-Riding the Ghost Whip-Riding the Ghost

Use the Grappleshot to board an enemy Ghost.

As you explore the open world of Zeta Halo, you’ll eventually come across enemy Ghosts. For this, just aim at the Ghost and shoot it with the Grappleshot. You’ll be pulled to it and will hijack it.

After hijacking the Ghost, make sure to go run over an enemy with it and you’ll also earn the “Takes One to Make One” Achievement.


Wait, I Can Throw Those? Wait, I Can Throw Those?

Throw 50 fusion coils.

Fusion coils can be found immediately as you take control of Master Chief. There are multiple kinds of them to find and throw. These can be used to kill enemies. All you have to do is pick them up by holding and then throw them with cn_RT.

They look like what is pictured below, but they can come in many different colors. These are commonly found across Zeta Halo.


Bring Shiela Home Safely Bring Shiela Home Safely

Get the Scorpion all the way to the “House” without it blowing up.

This is earned during the story mission “The Road.” There’s a Scorpion near the beginning of this level. For this, you will need to keep that tank alive until the end of the mission. You can drive the tank through the entire mission, but you’ll be facing a lot of enemies and it may not make it the whole way.

You can actually leave the Scorpion behind and clear out the path on foot or with other vehicles. There are other vehicles near the Scorpion that you can use to clear out the path. There’s even a Wraith parked nearby. Just don’t go all the way to the end. You will eventually get to a second gate. Go through the gate and extend the bridge. Now, you can go back to the Scorpion and drive it safely to the end of the mission with the cleared out path. Just remember to not cross that bridge without the tank.


Takes One to Make One Takes One to Make One

Splatter an enemy with a Ghost.

Ghost’s can be found throughout Zeta Halo. All you have to do is drive one and run over an enemy. These are usually found around bases, but you will encounter them somewhat often while making your way across Zeta Halo.


Wars with Friends Wars with Friends

Bring some rescued UNSC Marines along for the ride into a main mission.

First, you will need to rescue some UNSC Marines. This can be done by capturing FOBs and by liberating captured squads throughout Zeta Halo.

Once you have some rescued Marines, go to an FOB and call in a vehicle. Get in the vehicle and honk the horn to get nearby NPCs to get in your vehicle. When they’re all in, drive to story objective and play it.

This may be slightly glitched in a good way as this popped for me by accident. I had one Marine NPC in a Razorback and this popped as I drove near the Tower en route to another objective. The Tower was a story location that I had already completed. So, this may count by simply visiting a story location after it’s completed with at least one Marine.


Wanna Have a Catch? Wanna Have a Catch?

Stick 50 enemies with grenades.

All you have to do here is throw grenades at enemies and have the grenades hit and stick to the enemies.

There are two grenade types that can stick to enemies. The plasma grenades and the Brute grenades will stick to enemies.

You’ll clearly know when you’ve stuck an enemy as you can see the grenade and the enemy will noticeably react to it.


A True Test of Legends A True Test of Legends

Complete all main campaign missions on Legendary difficulty.

See the “Headmaster” Achievement for more details.
