summary
Arena Breakout: Infinite introduces the Underworld Revenant and Nightmare’s Jaw collections. Level 30 players can claim free Supply Passes and use Koen for additional draws. Players looking to expand their in-game budget can buy Arena Breakout: Infinite Koens, then focus on their preferred rewards based on their budget.
1. Understand the Two Military Supply Collections
The Underworld Revenant × Nightmare’s Jaw event introduces two connected Military Supply pools. Although both collections share the same dark, supernatural aesthetic, their headline rewards are different.
· Underworld Revenant: Centers on the Nightmare character appearance.
· Nightmare’s Jaw: Centers on the new Nightmare’s Jaw melee weapon.
· Both pools contain matching firearm, equipment, and throwable cosmetics.
· The event begins on August 13, 2026.
The two collections are designed to work together visually, but you do not need to pursue both. Choosing one pool based on your preferred reward can help you avoid spending Koen unnecessarily.
2. Prioritize Underworld Revenant for the Nightmare Character
Underworld Revenant is the better choice if your primary goal is obtaining the Nightmare character appearance.
Nightmare uses an aggressive supernatural design featuring dark armor, glowing elements, skeletal details, and a masked appearance. Compared with Arena Breakout: Infinite's usual military presentation, the character looks more like a horror-themed boss than a conventional operator.
The collection also contains several matching weapon cosmetics:
· AEK Assault Rifle
· T03 Assault Rifle
· Desert Eagle Pistol
· Z3 Stun Grenade
This makes Underworld Revenant particularly attractive if you want to build a complete Nightmare-themed loadout.
3. Choose Nightmare’s Jaw for the Melee Reward
If melee cosmetics are more important to you, focus on the Nightmare’s Jaw Military Supply.
The headline reward is the Nightmare’s Jaw melee weapon, which uses the same dark fantasy aesthetic as the Nightmare character.
The pool also includes cosmetics for:
· U191 Marksman Rifle
· PP19-01 Submachine Gun
· M67 Frag Grenade
· Nightmare’s Jaw gear appearance
The weapon itself is cosmetic and does not provide an unfair combat advantage. Its value comes from its distinctive appearance and collector appeal.
4. Reach Level 30 Before Claiming the Free Passes
One of the most important steps is reaching Level 30.
Eligible Level 30 accounts receive:
· 10 Underworld Revenant Supply Passes
· 10 Nightmare’s Jaw Supply Passes
This gives you an initial opportunity to participate in both prize pools without spending Koen or Bonds.
However, remember that free passes do not guarantee the headline rewards. They provide free draws, not free ownership of Nightmare or Nightmare’s Jaw.
Therefore, claim the free passes first and evaluate your results before committing additional resources.
5. Use Koen Instead of Bonds When Appropriate
The most unusual feature of this event is the ability to purchase Supply Passes using ordinary Koen.
The exchange rate is:
· 1,500,000 Koen = 10 Supply Passes
· Maximum of 80 Koen-purchased passes per pool
· Maximum of 160 Koen-purchased passes across both pools
This means established players can use their accumulated in-game wealth to participate without immediately relying on premium Bonds.
The system is especially useful for players who have already built substantial Koen reserves through successful extraction, trading, and loot sales.
6. Calculate the Total Koen Cost Before Spending
Do not overlook the financial commitment.
Reaching the 80-pass limit for one pool requires eight purchases:
8 × 1,500,000 Koen = 12,000,000 Koen
Doing this for both pools requires:
12,000,000 + 12,000,000 = 24,000,000 Koen
Therefore, the full 160-pass Koen allocation costs 24 million Koen.
That is a major investment.
Before spending that amount, compare the cost with your current equipment reserves and future raid requirements. If 24 million Koen represents most of your savings, converting it into cosmetic draws may leave you unable to maintain high-quality raid kits.
7. Do Not Treat 160 Passes as a Guarantee
The maximum number of Koen-funded passes should not be confused with a guaranteed collection.
The Supply Passes provide additional opportunities to obtain rewards from the relevant pools, but the system remains a prize-pool mechanic.
If your goal is specifically Nightmare or Nightmare’s Jaw, inspect the current in-game draw rules, reward probabilities, progression requirements, and remaining costs before making a large investment.
A sensible approach is:
· Claim the free passes.
· Use them in your preferred pool.
· Check your resulting progression.
· Decide whether additional Koen spending is worthwhile.
· Only consider premium currency after evaluating the remaining cost.
This prevents an initially free promotion from turning into an uncontrolled expenditure.
8. Build a Complete Nightmare-Themed Loadout
If you obtain multiple Underworld Revenant rewards, consider combining them into a single visual loadout.
For example, the Nightmare appearance can be paired with the AEK or T03 weapon cosmetics, followed by the Desert Eagle and Z3 Stun Grenade.
For the Nightmare’s Jaw collection, you can instead combine the melee weapon with the U191 or PP19-01 and the M67 Frag Grenade.
Matching cosmetics are especially noticeable in Arena Breakout: Infinite because players frequently inspect weapons, switch equipment, and manage their inventory throughout a raid.
9. Complete the Character Challenge Missions
Do not rely exclusively on Military Supply draws.
The event also introduces Character Challenge Missions, providing additional ways to earn themed rewards.
Reported rewards include:
· Underworld Revenant Tag
· Castle Spray
· Summer Golden Gift Box
These missions are important for collectors because they provide progression outside the primary prize pools.
If you already obtain Nightmare, completing the associated challenges can help expand the overall cosmetic collection without depending entirely on additional draws.
10. Take Advantage of the Melee-Focused TV Station Event
The August update also introduces a melee-focused event on TV Station.
This is particularly relevant if you obtain Nightmare’s Jaw.
TV Station contains many enclosed spaces and short sightlines, making close-range encounters common. A melee-focused event removes much of the normal firearm advantage and emphasizes movement, timing, positioning, and melee engagement.
Although Nightmare’s Jaw does not provide a statistical advantage, the event creates an ideal environment for displaying and using the cosmetic.
Focus on movement and positioning rather than assuming the cosmetic itself will improve your combat performance.
11. Balance Cosmetic Spending Against Raid Expenses
Koen remains one of your most important practical resources.
Before purchasing Supply Passes, maintain enough currency for:
· Weapons
· Ammunition
· Armor
· Medical supplies
· Attachments
· Replacement equipment
· Key raid items
A cosmetic draw should come from surplus wealth rather than money required for ordinary progression.
A useful rule is to treat Koen spent on Supply Passes as discretionary spending. If losing 12 million or 24 million Koen would significantly affect your next several raids, save the money instead.
12. Remember That Cosmetics Do Not Increase Combat Power
Nightmare may look intimidating, but the character appearance does not make your operator stronger.
Likewise, Nightmare’s Jaw does not transform melee combat into a guaranteed win.
Your actual performance still depends on:
· Ammunition penetration
· Weapon selection
· Armor protection
· Attachments
· Positioning
· Audio awareness
· Squad coordination
· Extraction decisions
The cosmetic layer changes your visual identity, not the fundamental combat mechanics.
13. Use Successful Extractions to Fund the Event
For players who want to participate without spending premium currency, the most practical strategy is to make Koen through consistent extraction.
Focus on raids where your expected profit justifies the risk. Avoid unnecessary fights when carrying valuable loot, and extract once your inventory reaches a satisfactory value.
You can then gradually convert surplus Koen into Supply Passes.
This approach is safer than immediately spending your entire reserve. It also preserves the central Arena Breakout gameplay loop: raid, loot, extract, sell, reinvest, and repeat.
14. Take Advantage of the Wider Season 6 Events
Underworld Revenant and Nightmare’s Jaw are only part of the August 13 update.
Season 6: White Nights also features other activities, including the returning Warlord Tournament and Kamona Summer Festival content.
The Summer Festival provides an especially important reason to remain active because it is connected to the Koen-for-Supply-Pass exchange.
Meanwhile, Summer Showdown introduces the interactive Bubble Gun and associated Bubble Refills, creating a completely different cosmetic progression path.
Prioritize the activities that match your goals rather than attempting to complete every event simultaneously.
15. Expect a Strong Visual Contrast Across the Season
The Nightmare collection represents the darker side of Season 6.
Its infernal imagery contrasts sharply with the lighter summer-themed activities running at the same time.
That contrast is intentional. Arena Breakout: Infinite is increasingly expanding beyond strictly realistic military cosmetics, allowing players to use more exaggerated visual themes while keeping the underlying extraction mechanics intact.
If you prefer highly distinctive cosmetics, Nightmare is one of the stronger options available during this event period.
16. Follow This Efficient Event Strategy
For most players, the following sequence is the most efficient approach:
· Reach Level 30 to unlock the free Supply Passes.
· Claim all 20 free passes across both pools.
· Decide whether Nightmare or Nightmare’s Jaw is your priority.
· Use free passes before spending Koen.
· Keep enough Koen for normal raid operations.
· Purchase additional passes only from surplus funds.
· Complete Character Challenge Missions for secondary rewards.
· Participate in the melee TV Station event if you want to showcase Nightmare’s Jaw.
· Check the current draw progression before using premium currency.
· Stop spending once the remaining expected value no longer justifies the cost.
This approach maximizes participation while limiting unnecessary economic risk.
Conclusion
The Underworld Revenant × Nightmare’s Jaw event gives Arena Breakout: Infinite players two major cosmetic targets: the Nightmare character and the Nightmare’s Jaw melee weapon. Level 30 players receive ten free passes for each pool, while the Kamona Summer Festival provides up to 160 additional Koen-funded Supply Passes across both collections. Players who need more in-game currency can consider cheap Arena Breakout: Infinite Koens to support their Supply Pass purchases.
The key is to treat the event as a cosmetic investment rather than a combat upgrade. Claim the free passes first, prioritize one collection, calculate the 24-million-Koen maximum cost carefully, and spend only from genuine surplus. Successful extraction can then become the foundation for your cosmetic progression without compromising your ability to survive future raids.
