HALO 3 LEGACY PLAYLIST

Dig that floaty feeling. The Delta Arena: Halo 3 Legacy Playlist brings Delta Arena settings to a selection of fan-favorite maps—including Halo 3’s Guardian, Narrows, Cold Storage, and Ghost Town, available for the first time in Halo Infinite matchmaking.

Here’s how we’ve mixed up the magic for this special occasion:

Jump into Halo Infinite multiplayer this month and return to form in these retrofied modes:

GRIFBALL RETURNS

Return to the original gravity-wrecking gridiron! In this amped-up version of Grifball, we’re combining wonky physics with creative combat for the most intense sportsball action yet. With full-contact equipment, third-person modes, and ten new arenas to smatter with your opponents’ bits, you’ve never seen Grifball like this.

NEW GRIFBALL MODES

Grifball rears its ugly head in both Classic and Thruster-equipped Octane modes—plus third-person (3P) variants for a wider look at the impending carnage. Lob, launch, and conquer in all four Grifball game modes starting today:

Are you ready to catch the disease?

CUSTOM TUNING

To capture the frenzy of traditional Grifball, we’ve reduced the swing cooldown period for the Gravity Hammer, juiced up the hammer physics, and swapped Energy Swords for the Duelist variant to make use of its long-range feints for dancing.

With these gameplay tweaks baked in, you can control the court with hammer jumps, launch players, pass the ball, have dance duels, and deny goals with timely deflections.

RULES FOR N00BS

In Grifball, 4v4 teams armed with Gravity Hammers and Energy Swords must fight for control of the sportsball and guard their Runner as they rush to score on the enemy goal. Once they’ve secured the ball, Runners unlock Overshields and improved forward movement speed, but their footwork is slightly less fancy when retreating.

When the hammer comes a-knocking, stiff-arm assailants with a well-timed punch, or hurl the ball free of the fracas just to keep it alive. (You probably won’t be so lucky.) Stay close to your defenders, watch for gaps, and get ready to be launched if things get tight!

Matches last for up to five three-minute rounds, with one minute of overtime to settle disputes. The first team to score three points wins the game, or else the leader takes all after five rounds have expired.

Time to dance, smash, and slash your way to glory! Head to our Grifball Playlist blog for arena details, pro tips, and a slice of Grifball history.

OPERATION PASS

Operation: Legacy’s free 20-tier Operation Pass resurrects the menacing mug of the EOD GEN1 helmet, faithfully restored to its Halo 3 design.

FREE OPERATION PASS

Designed to reorient concussive blasts around the wearer’s head (and thereby retain it), the EOD GEN1 betokens a simpler time in military engineering, when decapitation still ranked among the worst things that could happen to a soldier of the UNSC.

Complete the latest free 20-tier Operation Pass by July 8 to earn the EOD GEN1 armor set, a healthy heap of Spartan Points, and the Adrift in Space emblem—a nod to one stubborn jumper’s other favorite pastime.

PREMIUM OPERATION PASS

Upgrade to the Premium Operation Pass to unlock a durable reward track that never expires, earn bonus XP, and activate one additional challenge slot. Premium Pass holders will also receive the exclusive Reavian Tooth VK78 Commando weapon model and the Perilous Forest coating.

DOUBLE TROUBLE

CLASSIC SECURITY

Nothing says “security” like a bubbled dome and a set of beefcake shoulders. Originally produced at the Martian factory of Misriah Armories at the onset of the Human-Covenant War, the Security GEN1 model returns to offer a prodigious rebuke to a new generation of extraterrestrial intruders.
