What’s New in Marathon Season 2: Nightfall?

Season 2 is a direct response to Season 1’s biggest pain points. Systems that felt grindy and restrictive are being simplified, and a full seasonal reset paired with a free open play week makes this the best entry point the game has had. Here’s the short version:

• Night Marsh — a darkness-focused version of Dire Marsh where flashlights, flares, and visibility are active mechanics.
• Sentinel — a new defensive runner shell built to hold positions and counter grenade-heavy combat.
• Two new weapons — the KKV-9SD suppressed SMG and the D54 Battle Pistol.
• The Cradle — a unified account-wide progression system replacing the old faction-based upgrade paths.
• Faster faction progression — relaxed contracts, a ranked overhaul, a permanent duos queue, and major quality of life improvements.
• Free open play week — June 2nd to June 9th. Full game access across all platforms, progress carries over.

Night Marsh is a nighttime version of Dire Marsh, and it isn’t just a visual reskin. Darkness is an active mechanical layer here — every player spawns with a flashlight by default, and that single change fundamentally alters how you think about the map. Visibility becomes something you actively manage rather than take for granted.

The Flashlight Trade-Off:

Turn the flashlight on and you can clear rooms properly and avoid threats — but you’re also broadcasting your position in a way that doesn’t exist on any other map. Every piece of Night Marsh’s new gear is built around this push and pull between seeing and being seen.

• Vector Rounds — illuminate impact points where they land.
• Flares — light up areas of the environment on demand.
• Dark Site Scopes — provide short bursts of visibility without giving you away.

Complex Control is a previously locked area within Dire Marsh that has been unlocked for Season 2 — signalling a shift where formerly inaccessible parts of maps will gradually open up over future updates, keeping older locations feeling fresh.

Night Marsh adds a new structural layer to how runs play out through the UESC Cert system. Instead of simply moving through the map and deciding when to extract based on timing or loot, you now collect UESC Certs from enemies and spend them as an access currency throughout the run.

What UESC Certs Let You Do:

• Activate exfil points — spend certs to trigger a faster, more controlled extraction when you’re ready to leave.
• Hack Network Towers — unlock weapon and supply stockpiles that aren’t accessible otherwise.
• Open locked sections of Complex Control — access areas of the map most players won’t see every run.

The core decision: spend certs early for a quicker, safer extraction — or push deeper, build more certs, and take higher-risk routes for better rewards and rare map access.

Sentinel is the first new runner shell added to Marathon since launch, and it’s clearly a response to how Season 1 combat evolved. High-stakes areas like Cryo Archive often devolved into grenade spam followed by bubble defenses. Sentinel counters that loop — it’s for players who want to anchor a position and actually hold it under pressure rather than constantly rotating or disengaging.

Sentinel Kit Breakdown:

• Prime Ability — Defender System: deploys a system that automatically destroys incoming grenades and missiles while granting nearby teammates a weapon handling boost.
• Tactical — Snare Mine: plants a trap that slows any enemy who pushes into it, punishing aggressive rushes.
• Trait — Castle Doctrine: grants increased resistances after taking splash damage, and boosts close-range weapon handling speeds when you’re surrounded.
• Short-Range Tracking: helps you detect nearby enemy movement, giving you early warning before an engagement starts.

The Cradle is the most structurally significant change in Season 2. It replaces the old faction-based progression — which felt segmented and confusing in Season 1 — with a single unified account-wide system shared across all runner shells.

How It Works

At the Convert Matter screen, take weapons, gear, and items you don’t need and convert them into Energy, which feeds directly into leveling up your Cradle. As the Cradle levels, you allocate that Energy across six stat categories for your runner shell — and you can reallocate it at any time without penalty, so there’s no permanent commitment to a single build path.

Season 2 adds two new weapons, both designed to fill specific gaps in the sandbox rather than simply adding more firepower. Neither is a straight upgrade to anything already in the game.

KKV-9SD — Suppressed Close-Range SMG

A pistol-framed SMG with a built-in suppressor and an extremely high rate of fire — 1,200 RPM. It’s built for fast close-quarters engagements, and the suppressor gives you lethality without the audio signature most close-range weapons carry. Its Folding Stock mechanic lets you fold it for hipfire focus or close it for improved ADS, adapting to the range mid-fight.

D54 Battle Pistol — Flexible Sidearm Backup

The D54 sits between a sidearm and a primary backup. It supports both full auto and burst fire, comes with an integrated red-dot optic, and is designed for close-range defense and 1v1 duels rather than serving as a main entry weapon — coverage without committing your whole loadout to close range.

Season 2’s faction and contract changes are about removing friction rather than reinventing the system. The goal is for progression to happen naturally as you play, instead of forcing you to stop and grind specific activities.

Faction Progression Improvements

You earn more reputation across the board — standard contracts reward more, and reputation can now come from additional sources like valuables and defeating UESC enemies. Faction level requirements and material costs have been toned down, with the goal that most regular players can reach VIP rank within a season without it feeling like a second job.

Contract Changes

Many of Season 1’s most restrictive contract requirements are being relaxed — fewer “do everything in a single run” demands, and Cryo Archive contracts no longer constantly force you into vault key situations. Most importantly, progression now carries across multiple runs, so contracts feel less punishing if you don’t fully commit every time you load in.

These aren’t headline features, but they’re the changes you’ll feel immediately the moment you’re back in the game.

• Vault expanded to 512 grid spaces — hold gear for multiple builds without constantly discarding.
• Batch item selection — inventory cleanup between runs is far faster.
• Loot filtering — quickly see what fits your loadout, especially useful for weapon mods.
• Streamlined lobby and loadout menus — less menu-hopping before a match, with menu access while queued.
• Backend improvements — anti-cheat upgrade, CPU performance gains, PC frame generation, and network fixes to reduce disconnects (especially outside the US).

Ranked returns in Season 2 with a simplified structure that should feel more accessible and consistent than the Season 1 version.

Key Ranked Changes

• Single unified ranked queue — the previous low and high stakes queues merge into one mode with a minimum loadout value requirement, keeping matchmaking consistent.
• Sponsored kits based on rank — reduces gear fear so you can play ranked without risking your best loadout every match.
• Lobby-aware scoring — losses against higher-ranked lobbies hurt less, and wins against them reward more.
• Ranked-specific objectives — earn progression through activities like exfilling with tag chips, beyond just survival.

Following the success of experimental duo playlist testing, Season 2 adds a permanent dedicated duos queue. Not everyone has a full squad, and the duos format makes the game far more accessible for players who want a partner without needing three — it also makes clutching more viable if a teammate goes down.

To keep matchmaking healthy, the duos queue uses a daily rotating map playlist — cycling through Perimeter, Dire Marsh, Night Marsh, and Outpost — rather than being available on every map at once. This stops the playerbase from spreading too thin while still giving reliable access to the mode.

Marathon Season 2: Nightfall is a serious, direct response to what Season 1 got wrong. Night Marsh adds a genuinely new mechanical layer to the map pool, Sentinel fills a real gap in team compositions, and the Cradle removes most of the friction from progression without killing the long-term chase. The vault increase, contract relaxation, and ranked overhaul address the most consistently complained-about issues from launch — and a full free open play week with carry-over progress is about as good an on-ramp as Bungie could offer. If you’ve been on the fence about Marathon, Season 2 is the version worth trying.
