Delta Force Meltdown Season Guide: Maps, Modes, Weapons & Rewards

What Is the Meltdown Season

The Meltdown Season is the latest major content update for Delta Force, developed by Team Jade and launched on June 30, 2026 across PC, mobile, and console platforms. Described officially as the biggest update in the game's history, the season introduces two new maps spanning the Operations and Warfare modes, a new Engineer-class operator with cryogenic abilities, two new weapons, a tiltrotor transport helicopter, a Black Site decontamination system, a fully reset season mission progression, and the Ahsarah Cards in-match collectible card game.

The update is a no-downtime patch, meaning players can download and install it without scheduled server maintenance. The PC download size is approximately 33.5 GB, with the Steam update package reaching roughly 57.3 GB.

New Operator: N-Two

N-Two, whose real name is Gabriel Mercier, is the newest Engineer-class operator joining the roster. His kit revolves around cryogenic warfare — freezing enemies, slowing movement, and manipulating the battlefield through temperature control.

N-Two brings three distinct abilities. The Frost Launcher temporarily equips a launcher capable of firing up to six frost grenades that explode on impact, dealing damage and applying freeze effects. Sustained fire increases the rate of fire. The Cryo-Flask throws a frozen canister that releases cryogenic gas on impact, creating a sub-zero zone where enemies continuously accumulate freeze effects and cough violently. The Cryo-Flask can also freeze shut doors to block pathways. The Homing Stun Grenade is an auto-tracking stun grenade that disrupts enemy vision and deals damage.

The freeze effect behaves differently depending on the mode. In Operations, the cryogenic effect gradually slows enemy movement speed until full freeze, and reduces enemy fracture resistance. In Warfare, the same movement slowdown applies, but the effect also reduces vehicle handling — making N-Two a threat to both infantry and mechanized units.

Adding a new operator to your roster often requires currency or season progression.

New Maps

AZ3 Nuclear Plant — Operations Mode

AZ3 Nuclear Plant is the new Operations map, set inside a nuclear facility on the brink of catastrophe. The map features a radiation system where entering leak zones and searching radiation containers accumulates radiation exposure, which directly affects combat performance. The deeper players push into the facility, the more dangerous the environment becomes.

The map introduces a dynamic outcome system where player actions collectively determine how the crisis unfolds — ranging from a controlled shutdown to a full evacuation, ensuring that no two runs feel identical. Both Easy and Normal difficulty Operations are available on this map. Normal Operations requires an entry fee of 112,500 Tekniq Alloys.

A new boss, Neural Device Agent H1000, lurks deep within the core facility. Equipped with Neural Devices and connected to Skynet, H1000 is fast, lethal, and unpredictable — turning every encounter into a survival challenge.

Coliseum — Warfare Mode

Coliseum is the new Warfare map, featuring large-scale battles and a dual-branch major event system. The event centers on the Haavk rocket and its fate:

Coliseum also introduces an environmental combustion system exclusive to PC, where all vegetation and specific objects can be ignited, dealing damage and spreading fire within a set radius. Additional maps will receive this system in future updates.

New Weapons

Both weapons integrate into the existing gear ticket system. The RM277 replaces the MCX LT in the Elite Gear Ticket (Balanced) loadout, while the SVCH replaces the KC-17 in the Spec Ops Gear Ticket (Survival) and Season Custom Gear Ticket (Option 1) loadouts.

Nine new ammunition types accompany these weapons, spanning four ammunition series. The Overpressure series includes 5.8x42mm DVC12+P (Penetration Level 5) and DBP10+P (Penetration Level 4), both season-limited, which slow enemies on hit and increase hit stagger while reducing recoil during reloads. The CT series includes 9x19mm CT and .45 ACP CT, both Penetration Level 0, which deal increased limb damage but cannot be stored in the safe box. The PLY series is designed specifically for the RM277, available in three penetration levels with 90-round stack capacity and improving recoil control on sustained fire. The PAB series includes 9x39mm PAB-7 and PAB-9, which apply a 3-second vulnerability effect on hit, increasing subsequent damage to that body part up to a 60% cap.

New Vehicle: CSV-35 Transport Helicopter

The CSV-35 is a tiltrotor aircraft that combines the vertical takeoff and landing capabilities of a helicopter with the flight speed of a fixed-wing aircraft. It enables rapid deployment of combat personnel to objective positions and can be modified with weapon systems for self-defense.

In Warfare mode, the CSV-35 has been integrated into multiple maps with specific deployment adjustments. On Akh Canal in Attack/Defend and Victory Unite modes, the Sector B attacker assault vehicle is replaced by the CSV-35 during low-troop situations, and one Sector D defender assault vehicle is replaced by an LAV-AA. On Fault in Attack/Defend, the Sector B attacker assault helicopter is swapped for the CSV-35. On Ascension in Attack/Defend, a score-based CSV-35 is added for both sides in Sector D.

Black Site System: Decontamination Chamber

The Meltdown Season introduces a new Black Site facility called the Decontamination Chamber, which provides radiation resistance improvements and natural radiation decay. The system has three upgrade tiers tied to Operations level progression:

Season Mission System and S10 Progression

The S9 season has been fully reset — all progress is cleared, and the previous season's Ultimate Safe Box Season Pass and all safe box trial cards (used or unused) have expired.

S10 introduces a new mission progression with an Investigation Board that unveils intelligence about the AZ3 Nuclear Plant incident as players advance through the main storyline. The final mission features a choice-based branching system where the player's decision determines the fate of the AZ3 Nuclear Plant core facility. S10 season badges come in two different styles depending on this final choice, and each operator can earn only one badge — the badge style and name must be discovered in-game.

The S10 Ultimate Safe Box Deluxe Collection appearance is also new, featuring season-exclusive cosmetics.

Season resets mean everyone starts from zero — a perfect time to push for top rankings. If you are grinding through S10 missions and need to gear up quickly, Topuplist provides a reliable Delta Force top-up service with fast delivery and multiple payment options, helping you stay competitive from day one of the new season.

Ranked Mode

Both Operations and Warfare ranked modes entered an off-season break on June 30, with matchmaking and market functions temporarily suspended during the update window. Ranked play resumes with the new season, giving all players a fresh start on the leaderboards. The season reset ensures that previous ranking progress does not carry over, creating an even playing field for the S10 competitive cycle.

Twitch Drops

Delta Force supports Twitch Drops, allowing players to earn free in-game rewards by watching eligible streams. To participate, players must link their game account to their Twitch account through the official Drops page, then watch any livestream in the Delta Force Twitch category that has Drops activated.

Rewards are delivered to the in-game mailbox and expire 30 days after delivery. Each Twitch account can claim each specific Drop reward only once, and reconnecting to a different game character does not allow duplicate claims. Only one active channel's watch time counts at a time — watching multiple streams simultaneously does not accelerate progress.

Warfare Mode Updates

The Meltdown Season introduces several Warfare mode improvements. A new Secondary Objective system in Attack/Defend mode allows attackers to capture secondary objectives and hold them for 60 seconds to unlock a redeployment point at that location. Secondary objective control does not affect the overall sector capture progress. This system is currently active on Coliseum Sectors B and D, and Monument Sector D.

New fixed weapon emplacements have been added. The Vulcan Cannon replaces some existing 30mm anti-air guns, and the Auto Vulcan Cannon automatically targets enemy aircraft within range with increasing efficiency as targets approach closer.

Dynamic vehicle deployment positions are now active on Fault and Threshold in Attack/Defend and Victory Unite modes. Vehicle spawn locations are randomly selected within defined areas, with position and orientation adjusting if enemy units are detected nearby.

Additional map adjustments include a modified Sector B attacker redeployment zone on Threshold to prevent clipping into concrete barriers, a restricted Sector C rooftop airdrop on Threshold, optimized Sector B artillery visual effects on Trench Lines for improved frame rates on PC, and a new secondary objective on Monument Sector D to give attackers more routes and footholds.

Ahsarah Cards — In-Match Card Game

A new collectible card system called Ahsarah Cards has been added to Operations mode. Cards and Card Boxes can be found during matches, and collected cards can be stored in Card Boxes outside of matches. Players can assemble a complete, non-duplicate deck of Ahsarah Cards in a Card Box, bring it into a match, and play a card game with friends.

Ahsarah Cards are quality-graded by rank: Card Boxes and Big Jokers are red, Little Jokers are gold, Aces are purple, cards J through K are blue, and cards 2 through 10 are green. Ahsarah Card series cards cannot be listed on the auction house.

Operator Balance Changes

Several operators received balance adjustments in the Meltdown Season. Morse received sonar device preview lines and teammate-shared minimap markings as buffs, but his Throwable Jammer was significantly nerfed with increased pull-pin sound range, added warning visibility for enemies, increased explosion delay, and reduced stun effect on camera rotation. Gizmo's Crawler Nest had its T.I.M. detection range and lock-on movement speed reduced in Operations. Shepherd gained a visible paralyzed-enemy count in Operations but lost full-map device marking visibility in Warfare. Sineva received faster weapon switching when disengaging the EOD Set. Tempest's Drill Charge damage was reduced from 60 to 40 in Warfare. Toxik's Dragonfly Swarm System HP drain was substantially increased in Operations, with escalating damage over time. Vlinder's Remote Rescue score was increased from 25 to 50 in Warfare.

Weapon Balance Changes

In Operations mode, the M7 Battle Rifle had its base limb damage multiplier reduced from 0.4x to 0.35x and damage reduced from 38 to 37, with the M7 Tidal Extended Barrel Combo damage reduced from 40 to 39. The AS Val had its damage reduced from 29 to 28 and armor penetration reduced from 48 to 44. The AK-12 had its base limb damage multiplier increased from 0.4x to 0.45x.

In Warfare mode, the SG552 assault rifle had its range falloff extended, with the first falloff distance increasing from 40m to 50m and the second from 50m to 60m. The MP7 submachine gun had its range falloff reduced, with the first falloff distance decreasing from 20m to 16m and the second from 30m to 25m.

New Collectibles and System Features

The season adds a range of new collectibles across multiple quality tiers. Red-tier items include the Reactor Cooling Core, Enriched Uranium Sample, and Ahsarah Card Box with Big Joker. Gold-tier items include the Micro Fuel Rod, Portable Isotope Identifier, Military Pass, and Haavk Intelligence Gear. Purple, blue, and green tiers include the Infusion Warmer, Portable Dye Bottle, Insignia Patch, and the full range of Ahsarah Cards.

A new Deluxe Charm Cabinet system allows players to display any Deluxe Charms they own, with a season-specific cabinet effect activating when all legendary deluxe charms for the season (including hidden ones) are collected. The Deluxe Market has been updated with a new Legendary Deluxe appearance recommendation tab featuring appearance template recommendations and sales rankings. Collected melee weapons can now be added to a favorites list from the Collection page, and a random collected appearance is equipped when entering a match.

Two new achievements have been added. G.T.I. Superman requires eliminating 7 enemy operators in a single Normal AZ3 Nuclear Plant match while at maximum radiation exposure. Carjacked requires successfully hijacking one enemy ground Chariot-type vehicle in ranked or Victory Unite mode, excluding assault vehicles, ATVs, and light tactical vehicles.

New Costumes and Store Updates

The Moran King of Flowers costume is available through a Costume Gacha system using Worn-Out Scripts, purchasable from the Ticket Shop. The costume includes full voice acting, a Burst Skill cutscene animation, and special SD animations. The JUNKYARD PASS event pass offers the E.H. Junkyard Vanguard costume as its premium track reward. The July Mission Pass features the Naga Ring Ensemble costume. Two costume reruns — Sugar Wild Backyard and Leona Zoo Keeper — return to the cash shop for a limited time.

The T&E Lab supply station has been updated with AZ3 Nuclear Plant Lv.4 Access Card Selection Packs and Rare Access Card Selection Packs available as one-time discounted purchases. The .50 BMG ammunition crafting cost has been reduced in Black Site.

With new costumes, gear tickets, and supply packs all dropping at once, the Meltdown Season can put serious pressure on your in-game currency. For players looking to stay ahead of the curve, Topuplist offers a trusted Delta Force top-up platform — instant delivery, region-appropriate pricing, and support for multiple payment methods make it easy to keep your loadout competitive throughout the season.

Rainbow Six Siege Collaboration

The Meltdown Season includes a collaboration with Rainbow Six Siege, bringing themed operators and weapon skins to Delta Force. Additional collaboration content is expected to be revealed as the season progresses.

Removed Content

The Treasure Trove mode has been removed for this season. Undiscovered buried treasures from previous runs have been recorded and will be redistributed in future events. The Ahsarah Legend: Traces of the Master parkour mode has also been removed.
