Arena Breakout: Infinite has rolled its Season 7: Utopia zombie push into a full autumn celebration. On September 24, 2026, Morefun Studios announced the Biohazard & Bountiful Autumn Festival — a multi-track event that brings back Supplies Drops 2.0, drops a 780,000 Koen Lunar Soil Sample collectible into the Dark Zone, and hands out a free Hazmat Suit set through weekly challenges. Most of the event content unlocks on September 28, and the paid and challenge tracks run as late as October 28, 2026.
If you have been grinding the new zombie modes since Utopia went live on September 16, this is the event that pays you back for it. Below is the full breakdown — every reward track, the exact dates, how Supplies Drops 2.0 actually changed, and where that six-figure collectible spawns — verified against Morefun's official Steam announcement for app 2073620.
Quick answer: what is the Autumn Festival in Arena Breakout: Infinite?
The Biohazard & Bountiful Autumn Festival is a limited-time seasonal event running inside Season 7: Utopia, announced September 24, 2026. It layers onto the ongoing Biohazard (zombie) event series and adds twelve reward tracks: the returning Supplies Drops 2.0 co-op mode, a Bountiful Autumn Store, the Lunar Soil Sample collectible (worth 780,000 Koen), autumn challenges, a free Hazmat Suit set from the Extermination Mission track, a Merit-to-Koen conversion, Zombie No Man's Land passes, the returning Trash to Treasure smelting event, and paid Battle Pass and bundle upgrades. Check-in rewards start September 24; most other tracks open September 28.

Supplies Drops 2.0 — the co-op mode that returns
Supplies Drops first arrived in Season 6 as a casual co-op mode with unlimited respawns and system-issued loadouts, where you looted into a Personal Crate and a shared Squad Crate that split at raid end. Supplies Drops 2.0 keeps that shape but bolts on a full progression layer. Here is what changed, straight from the patch note.
Reward Crate Levels (five tiers)
You raise your Reward Crate by searching containers, eliminating players, and interacting with Terminals. There are 5 levels:
- Lv. 1: Starts with 4 rows.
- Lv. 2: +1 row to the Squad Reward Crate.
- Lv. 3: Unlocks the Smelter.
- Lv. 4: +1 row to the Squad Reward Crate.
- Lv. 5: +1 row to both the Squad Reward Crate and the Personal Reward Crate.
More crate rows means more loot survives to the settlement screen, so pushing to Lv. 5 as a squad is the single biggest lever on your take-home.
Terminals — the new objective
Two Terminal types now seed the map and feed Reward Crate XP:
- Standard Terminal: Each team can interact once for a small amount of Reward Crate XP. Multiple are available across the map.
- Confidential Terminal: After you interact, your team must stay and defend it while other teams contest. Securing it grants a large amount of Reward Crate XP. There is only one on the entire map.
That single Confidential Terminal is the fight of the raid — it is the fastest route to Lv. 5, and every other squad knows it.
The Smelter
Unlocked at Reward Crate Lv. 3, the Smelter lets you convert Purple-quality items and below into new items, with no usage limit. It is a built-in loot-recycler for the casual mode, so junk you would normally leave becomes fuel for a better pull.
Other Supplies Drops 2.0 adjustments
Morefun also tuned the pacing and reward feel:
- Higher-value entry passes and more content and loot per raid.
- Revive time increases as the raid progresses (early deaths are cheap, late deaths hurt).
- Kill and XP reward announcements added.
- Airdrop frequency increases in the mid-to-late stages.
- Team numbers and more phase-based voice announcements added.
- Special heavily armored AI units now spawn on the map.
If you are still figuring out the wider zombie ecosystem, our Season 7 Utopia zombie mode guide covers Infected Zone versus Zombie Endless, and the Season 7 overview explains the wider systems those armored AI units belong to.
The Lunar Soil Sample — a 780,000 Koen collectible
The headline loot chase is the Lunar Soil Sample, a 2×2 collectible worth 780,000 Koen that appears in the Dark Zone for a limited time during the event.
- Where it spawns: from safes on all maps. It is a chance drop, not a guaranteed pickup — the more high-value safes you crack, the more attempts you get.
- Size: 2×2 grid slots, so keep container space free if you are hunting it.
- Value: 780,000 Koen is a massive single-item payout — for context, that is well north of what most full raids net, which is why it is worth deliberately running safe-dense zones while the event is live.
Because Koen cannot be bought with real money in Arena Breakout: Infinite (Morefun removed that system at the 1.0 launch), a six-figure collectible like this is one of the fastest legitimate income spikes in the game. If you want the sustainable version, our how to make Koen fast guide covers barter flips and Market-slot optimization.
Where does the Lunar Soil Sample spawn? It can appear in safes on any map during the Autumn Festival. Airport has the highest overall drop rates and the densest safe layout, so it is a strong farm target — see our Airport map guide for safe locations and extraction routes.
The Hazmat Suit set — free armor-to-weapons from the Extermination Mission
The Extermination Mission track is where you earn the full Hazmat Suit set for free — Morefun states it covers "from armor to weapons."
Here is how the track works:
- Complete challenges during the event to earn Stars. Each task has three tiers, awarding 1 Star per tier, up to 3 Stars per task.
- Earn enough Stars each week to claim the corresponding rewards.
- Tasks refresh every Monday at 5:00 AM, with new task types randomly selected after each refresh.
- Weekly Star rewards reset every Monday at 5:00 AM. Unclaimed rewards are not reissued — claim before the weekly rollover or lose them.
- Weekly challenges pay out Hazmat Suit Supply Passes; draw from the Supply Pool with them to obtain the full set.
- Leftover passes convert at 1 Pass = 5,000 Koen when the event expires, so unspent passes are not wasted — but drawing the set first is the better value.
The "claim before Monday 5:00 AM" rule is the trap here: this is a weekly-reset ladder, not a stockpile you can cash in on the last day.
Every Autumn Festival reward track
Beyond Supplies Drops 2.0, the Lunar Soil Sample, and the Hazmat Suit, the festival stacks nine more tracks. Here is the full slate with dates and what each pays.
| Track | Starts | What you get |
|---|---|---|
| Autumn Gift (check-in) | Sep 24 | Free weapon skins and other rewards for logging in and doing simple challenges |
| Bountiful Autumn Store | Sep 28 | Redeem points for weapon skins; free choice of one Tac-Master skin — T191 or M24 |
| Bountiful Autumn Challenge | Sep 28 | Complete autumn challenges for a Random Featured Weapon Bundle and more |
| Lunar Soil Sample | During event | 2×2 collectible worth 780,000 Koen from safes on all maps |
| Extermination Mission | Weekly (Mon 5 AM reset) | Hazmat Suit set via Supply Passes (armor to weapons) |
| Merit Challenge | Weekly | Highest weekly Merit in Biohazard Endless converts to 3× Koen, up to 3,000,000 Koen/week |
| Zombies No Man's Land | Weekly | Log-in passes + milestone passes at 4/8/16 daily tasks; passes also drop in Infected Area raids |
| Dark Zone Patrol | Sep 28 | Send companion Paul to patrol Kamona for valuables |
| Vinson's Challenge | Sep 28 – Oct 28 | Spend Koen on the event page to accept challenges for rewards (Koen spent is non-refundable) |
| Trash to Treasure | During event | Returning smelt event — convert loot into better items |
| Battle Pass upgrade | During event | Upgrade the S7 Battle Pass for 500 Bonds instantly, plus skins, an outfit, and Koen |
| Limited-Time Bundles | During event | $4.50 each for 450 Bonds + 7-Day Elite Card + exclusive gun skin (6 bundles total) |
Two tracks are worth flagging. Merit Challenge can pay up to 3,000,000 Koen a week for topping Biohazard Endless Merit — genuinely the largest Koen faucet in the event. And Vinson's Challenge costs Koen to enter and does not refund if you fail, so only accept a challenge you can actually clear.
There is also a Season 7 Discord event live now with a prize pool of up to 1,000 Bonds and a surprise grand prize — a free RTX 5060.
Is the Autumn Festival worth playing?
Yes — more than most seasonal events, because the payouts are unusually large and mostly free. The Lunar Soil Sample (780,000 Koen) and the Merit Challenge (up to 3,000,000 Koen/week) alone can reset a wiped-out stash, and the Hazmat Suit set is a full free kit. The only real spend is optional: the 500-Bond Battle Pass upgrade and the $4.50 bundles, both of which buy Bonds and cosmetics, never Koen or power.
Remember the core Arena Breakout: Infinite rule that separates it from pay-to-win extraction shooters: you cannot buy Koen with real money, so every Koen reward on this event has to be earned in a raid. That is exactly why an event with a 780K collectible and a 3M/week Merit faucet matters — it is free, legitimate income at a scale you cannot pay to skip.
FAQ
When does the Arena Breakout: Infinite Autumn Festival start and end? The Biohazard & Bountiful Autumn Festival was announced September 24, 2026. Autumn Gift check-in rewards start September 24; most tracks (the Bountiful Autumn Store, Challenge, Dark Zone Patrol, and Vinson's Challenge) open September 28. Vinson's Challenge runs through October 28, 2026. It takes place inside Season 7: Utopia, which launched September 16, 2026.
Where does the Lunar Soil Sample spawn in Arena Breakout: Infinite? The Lunar Soil Sample is a 2×2 collectible worth 780,000 Koen that appears in safes on all maps in the Dark Zone during the event. It is a chance drop, so cracking more high-value safes gives you more attempts. Airport is a strong farm target thanks to its dense safe layout and high drop rates.
How do you get the Hazmat Suit set for free? Complete Extermination Mission challenges to earn Stars (up to 3 per task), then hit the weekly Star thresholds to claim Hazmat Suit Supply Passes. Draw from the Supply Pool with those passes to obtain the full set, which runs from armor to weapons. Tasks and rewards reset every Monday at 5:00 AM, and unclaimed rewards are not reissued — claim before the weekly rollover.
What is new in Supplies Drops 2.0? Supplies Drops 2.0 adds a five-level Reward Crate progression (with extra Squad and Personal Crate rows), Standard and Confidential Terminals that grant Reward Crate XP, and a Smelter (unlocked at Reward Crate Lv. 3) that converts Purple-quality items and below into new items with no usage limit. It also increases loot and entry-pass value, scales revive time up as the raid progresses, raises mid-to-late airdrop frequency, and adds special heavily armored AI units.
How much Koen can you earn from the Autumn Festival? The biggest faucets are the Lunar Soil Sample (a single 780,000 Koen collectible) and the Merit Challenge, which converts your highest weekly Biohazard Endless Merit into 3× Koen, up to 3,000,000 Koen per week. Because Koen cannot be purchased with real money in Arena Breakout: Infinite, these in-raid rewards are among the fastest legitimate income spikes available.
Can you buy the Autumn Festival rewards with real money? No Koen or gameplay power is for sale. The only paid options are the Season 7 Battle Pass upgrade (500 Bonds instant plus cosmetics and Koen) and six Limited-Time Bundles at $4.50 each (450 Bonds, a 7-Day Elite Card, and a gun skin). Bonds buy cosmetics, passes, and convenience — never Koen.
