Halo Infinite Achievements Guide - Neoseeker

Halo Infinite's campaign has a total of 69 Achievements up for grabs. These are awarded for experiencing the entirety of the single player campaign, unlocking suit abilities, nabbing a whole lot of collectibles and undertaking a few challenging combat encounters in unique ways. Below you'll find a categorized list of the Achievements in the campaign and guides for how you can unlock each one.

Story Achievements

There are 21 Achievements in Halo Infinite that are tied into simply playing through the main game and progressing through the story to its end. The 21 Achievements below are unmissable and are listed in the order that they appear in our walkthrough. They include:

Difficulty Achievements

There are 4 additional difficult-based Achievements in Halo Infinite that will unlock once you complete the game on the specified difficulty (along with a Legendary challenge with a twist). These Achievements stack, so completing the game on a harder difficulty will unlock the Achievements for the lesser difficulties as well.

Missable Story Achievements

As the Halo Infinite campaign at this time does not allow you to replay levels (that feature is coming soon), there are, in addition to the story Achievements listed above 4 missable, story-related Achievements. If you miss these on your first run through, you'll have to start the game again from the beginning in order to re-attempt them (or just wait for the level reply to arrive). These include the following:

Achievement/TrophyHow to Unlock

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

To do this, you'll first need to capture a Forward Operating Base (FOB). This will allow you both to summon vehicles and have marines appear. Grab a vehicle at a FOB and the marines should hop in. Drive on over to a story mission with the marines on board to unlock the Achievement.

This can be done on any of the main missions that are accessible from the world map.

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

This can be attempted during the mission Pelican Down. Simply make your way through the area and take out all three of the AA Guns within 20 minutes of crash landing to earn yourself the Achievement.

HI Bring Shiela Home Safely.jpg Bring Sheila Home Safely

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

This can be attempted during the mission The Road. At the start of the level you'll find among other vehicles, a Scorpion tank. Our goal is to take the Scorpion all the way from the starting area to the House of Reckoning at the end of the level without it being destroyed. If you choose to use it from the start, you will want to play with it conservatively and ditch it when it starts catching on fire. We can always return and grab it when we have cleared through to the final area. Once it has made it to the bridge leading to the House of Reckoning, the Achievement will unlock.

To earn this Achievement you need to start the game and work your way all the way through to the ending credits in under 8 hours. best saved for a second playthrough!

Armor Ability Achievements

Halo Infinite includes 9 Achievements for upgrading and making use of Master Chief's armor abilities. The five main abilities required are all unlocked through story progression. Once they are unlocked, we'll just need to find Spartan Cores in the field and use them to upgrade these abilities to max level, as well as use each 50 times to unlock the relevant Achievements. These include:

Collectible Achievements

These 16 Achievements are tied into finding and picking up various forms of collectibles hidden throughout the Halo Infinite main campaign and attached open world. Check out either the chapter walkthroughs or the chapter collectible pages for locations. These include Skulls, various types of Audio Logs, Mjolnir Armor Lockers, Spartan Cores, Forerunner Artifacts, and Propaganda Towers. These Achievements/Trophies include:

Open World Activity Achievements

There are 9 Achievements tied into the open world activities available in Halo Infinite, likely popped into the game to encourage those Achievement/Trophy hunters out there to experience everything the game has to offer. Each of these are fairly self-explanatory and can be obtained by following the relevant sections in the above guide. Here are a list of the achievements/trophies that fall into this category and what needs to be done to unlock each of them:

Miscellaneous Achievements/Trophies

The following 6 Achievements/Trophies were a little hard to narrow down into one of the other categories so they find themselves in the miscellaneous box. These require you to reach the highest point on the map, do some interesting things in vehicles and play with grenades and other projectiles in certain ways. Without further ado, here are the related Achievements:
