Halo Infinite is here, check out the beginner’s guide.jpg

Halo Infinite is here, and it’s time to step back into the role of Master Chief. This time, you’ll be exploring the mysterious Zeta Halo in the first open-world Halo game. You’ll still be shooting aliens and driving Warthogs, but you’ll also have a lot more freedom to explore and find some familiar open-world game tropes in the Halo style.

In this Halo Infinite beginner’s guide, we’ll give you our best advice, along with some tips and tricks to get you started on Infinite’s campaign whether you’re a returning veteran or a newcomer.


The first hours of Halo Infinite precede its open world. Take advantage of this time while the game is easiest to learn about new weapons and how to use them.

There are a lot of guns in Halo Infinite. You’ll start with the standard pistol and assault rifle, but there are dozens more. Each has its own quirks and strengths. You’re also going to run out of ammo constantly — it takes a lot of bullets to put down those alien enemies — so it makes sense to change up your loadout as a necessity (and lack of bullets) dictates.

Use Infinite’s introduction to swap between a lot of different weapons so you can start to understand them better. You’ll be thankful you did as the firefights get more and more intense.

There’s even an easy way to spot those guns …


Halo Infinite Scan

Pressing down on your controller’s D-pad triggers your AI scanner. This highlights things like weapons and crates around you (and even behind walls). Weapons appear blue and interaction objects — things like Spartan Cores, explosive coils, and control terminals — appear yellow. It also highlights any current mission objectives on your HUD.

Get in the habit of using your AI scan early.


In Halo Infinite, Master Chief gets a sci-fi version of Link’s hookshot from The Legend of Zelda. It’s easily our favorite addition to the Halo universe. Using it for navigation is obvious — you’ll use it to climb up and over things a lot. But there’s a lot more to do with it than just zipping around Zeta Halo.

Try these strategies out early and often to use your Grappleshot effectively:

  • Jackal Shields. Hit a Jackal’s shield with the Grappleshot, and it’ll knock it to the side, exposing the Jackal to headshots.
  • Close distance rapidly. Hitting an (unshielded) enemy with the Grappleshot zips you over to them and lets you deliver a melee blow at the end of the trip. It’s great for when you (finally) pop the shields of an Elite.
  • Hijack vehicles. Hitting a vehicle with your Grappleshot shoots you onto the vehicle and automatically start the hijacking process.


Halo Infinite also allows you to upgrade Master Chief’s gear to improve the Grappleshot, Shield Core, Threat Sensor, Drop Wall, and Thrusters, which you pick up over the first few story missions. You’ll upgrade them with all with Spartan Cores.

Without question, our favorite upgrade is the Grappleshot. You’ll increase its range and add stunning electrocution to it with just a couple of Spartan Cores worth of upgrades.

A close second is upgrading your Shield Core. Each upgrade increases the strength of your shields by 15% — and extra shields just mean you get to spend more time shooting the bad guys (and ideally less time dying).

Upgrades and Spartan Cores – Halo Infinite guide
In Polygon’s Halo Infinite upgrades guide, we’ll explain what each piece of gear and upgrades are, how you upgrade them, and which to upgrade first.


There’s so much going on around Zeta Halo. There’re things like outposts, collectibles, Spartan Cores (that you need to upgrade your Grappleshot), multiplayer cosmetics, and quick combat encounters.

These various side missions and activities available between campaign missions fill out the world (ring) of Halo Infinite and give you more to experience than just the main story. More importantly, they reward you for the effort.

Some of these activities earn you Valor that upgrades Forward Operating Bases. Speaking of which …


Forward Operating Bases (FOBs) are resupply platforms scattered across Halo Infinite’s Zeta Halo. At a FOB, you can call in a vehicle, pick up ammo and weapons, as well as recruit Marine reinforcements. As you earn Valor, the vehicles, weapons, and Marines available at your controlled FOBs improves.

When you first discover a FOB, you’ll need to clear out the Banished that have taken it over. Once you control it, it reveals points of interest in the area and acts as a fast travel location.

Make (re)claiming FOBs your priority. That way, you’ll be better equipped (and loaded up with ammo) for every challenge you take on, and you can fast travel around the ring without a lot of work.
