Delta Force S10 "Nuclear Fission" Season Update — Complete Operator, Weapons, Maps & Systems Guide

Introduction

Delta Force: Hawk Ops Season 10 "Nuclear Fission" launches on June 30, 2026 — the most content-dense seasonal update to date. This season introduces two disaster-themed maps: the radiation-soaked AZ3 Nuclear Power Plant and the extreme-cold White Storm. It also brings a brand-new Engineer crowd-control operator "Liquid Nitrogen" (Gabriel), two heavy-caliber weapons (SVTH and RM277), the game's first Nepal-style premium melee weapon (Dirge), an exclusive H1000 boss encounter, the Demulan playable-boss system, and a suite of long-requested system-level improvements including warehouse secondary password and death replay.

Whether you're a solo extraction player, a coordinated squad leader, or a loadout crafter, this guide covers every confirmed piece of S10 intelligence to help you hit the ground running on launch day.

2. New Engineer Operator: Liquid Nitrogen — Gabriel

Operator codename "Liquid Nitrogen," real name Gabriel Murrill, former Havoc nuclear facility cooling system engineer. Dismissed after a major accident during his tenure, he was later reactivated by G.T.I. His class is Engineer / Hard Control and Lockdown, arriving June 30, 2026 alongside the S10 season.

Signature voice line: "I will never make the same mistake again."

i. Passive: Cryo Attachment (Core Mechanic)

All skills and basic attacks apply a stacking cold debuff on hit, causing continuous slow. At max stacks, the target is frozen solid — unable to move, shoot, or reload for approximately 3 to 5 seconds, with only a manual break-free available. This effect also works on vehicles, severely degrading enemy vehicle handling and countering drive-rush tactics. The passive additionally reduces enemy fracture resistance.

ii. Tactical Item: Dewar Canister (Area Lockdown)

Holds up to 2 charges. When thrown, it releases a wide-area cryogenic vapor cloud. Enemies entering the zone continuously stack cold debuff, cough violently (revealing their position), take continuous damage, and are slowed. The canister cannot be destroyed by gunfire, making it ideal for long-term area denial of corridors, stairwells, and extraction points. Test server cooldown is approximately 1 minute.

iii. Tactical Ability: Thermal Tracking Shock Grenade (Recon and Disruption)

A homing shock grenade that automatically tracks nearby enemies. On detonation, it causes ear-ringing and vision blur. It auto-marks all enemies with cold debuff, revealing their silhouettes through walls — serving double duty as recon and crowd control. The explosion deals true damage with considerable output.

iv. Ultimate: Rapid-Fire Cryo Grenade Launcher (AoE Freeze)

Equips a custom 6-round cryo grenade launcher capable of rapid consecutive fire. Grenades create frost ground patches on impact, causing persistent slow and damage. Holding the fire key accelerates the rate of fire. Test server damage is approximately 20 per round; combined with the passive, it can freeze enemies in an area.

v. AZ3 Nuclear Power Plant Strategy

Corridors are narrow and engagement distances are short, making area lockdown extremely valuable. Throw canisters at reactor and radiation room entrances to block enemy pushes. In the final circle, use double canisters plus ultimate to lock down escape routes. Use the tracking grenade to flush out enemies hiding in radiation zones.

3. H1000 Boss Guide (Cyborg Agent — The Destroyer)

Spawn Rules: Spawns reliably in Classified mode. The fight has three phases — defeat the weaker clones H47 and H800 first, then the main body H1000 appears. After a kill, the full set respawns after approximately 10 minutes.

Appearance and Weakness: Bald, suited, sunglasses; exposed brain-machine interface on the head; the bio-symbol on the chest is the weak point. The area has persistent radiation damage.

Core Abilities: Primary weapon is an armor-piercing Desert Eagle; fires anesthesia poison needles (failure to remove causes stun); thrusting flying kick for instant melee kill; stacks radiation on close contact for continuous damage.

Drop Rewards: Killing H1000 guarantees a red AZ3 Key, which opens high-tier safes in the core area for Level 5 gear and high-value loot. Completing the emergency reactor shutdown beforehand weakens its armor.

4. S10 Melee Weapon: Dirge Nepal Combat Knife

The centerpiece of S10 melee content is the all-new Nepal combat knife — "Dirge" — the game's first Nepal-style melee weapon. Features a post-modern hardcore design aesthetic, classified as a heavy blade type with extremely high visual distinction.

5. S10 New Weapons: SVTH and RM277

i. SVTH Designated Marksman Rifle (7.62x54R)

The SVTH is the direct superior replacement for the SVD, chambered in 7.62x54R. Its biggest highlight is a switchable full-auto firing mode that completely overturns the traditional semi-auto DMR playstyle. Core stats:

Exclusive Attachments:

Chrome Burst Bolt: Boosts first three rounds to ~700 RPM, enhancing opening burst capability

Windfall Dual Magazine: Twin 20-round magazines in tandem for greatly extended sustain; features a new reload animation

SVTH Carbon Fiber Long Barrel: Unlocks full-auto firing mode when equipped

Custom Stock: Optimizes recoil control

ii. RM277 Assault Rifle (6.8x51mm)

The RM277 is the third weapon in the game using 6.8x51mm ammunition, sharing ammo specs with the M7 — but with a completely different design philosophy. The M7 leans toward high-rate-of-fire close-to-mid-range assault, while the RM277 is a mid-to-long-range suppression "stat monster." Core stats:

Core Characteristics: Uniform chest/abdomen damage (no distance falloff), extremely low horizontal and vertical recoil, and recoil that decreases per consecutive shot (more pronounced with 6.8x51mm PLY-III lightweight high-penetration ammo).

Severance Suppressor: Core attachment — no reduction to range or muzzle velocity; combines silence with mild recoil suppression and no penalties

Dedicated Recoil Pad: Reduces recoil during long bursts

Notable Weaknesses: Fire rate of only 550 RPM means indoor point-blank TTK is far worse than M7/M4; hip-fire accuracy is poor; the full set of long-range exclusive attachments is expensive to acquire.

6. New Map: AZ3 Nuclear Power Plant (Operations)

AZ3 Nuclear Power Plant is a high-density industrial map structured across three layers — above ground, underground, and coastal — with 9 major zones. It has only two fixed extraction points (speedboat dock and highway), emphasizing high-intensity close-quarters urban combat. The map offers Normal and Classified difficulties, with Classified entry costing 112,500 Havoc Coins.

i. Dynamic Radiation System

Radiation zones randomly spawn across the map. Entering without a gas mask or anti-radiation medication continuously accumulates radiation. Radiation has three escalating tiers:

White (mild): Visual noise; recovers slowly on its own

Orange (moderate): Continuous HP loss; vision blur intensifies

Red (severe): Permanently reduces max HP; failure to decontaminate leads to immediate elimination

Standard painkillers cannot remove radiation effects.

Shutdown Failure: Reactor power goes to maximum, triggering map-wide nuclear meltdown

ii. Additional Map Notes

Map Safes: The map has 7 safes total. They must be decrypted at white consoles — same mechanic as the Longbow Valley prison break-in.

Spawn-Point Exclusive Loot: Outer spawn points can yield AZ3 Keys that directly unlock exclusive room cards. These rooms have a chance to drop AZ3-exclusive weapons.

7. Boss Playable System: Demulan

S10 adds a boss-playable mode where players can consume a small amount of Havoc Coins to transform into the boss Demulan. The character is set as the Havoc Group's Aerospace Director, replacing S9's Saeed as the new playable boss.

Three Exclusive Skills

Hacker Scan: X-ray vision of all enemy players' equipment quality and positions across the entire map

Pulse Bomb: Disables all electronic accessories of enemies in range while causing blindness

Blue Eagle Precision Airstrike: Calls in a helicopter for wide-area artillery coverage and area clearance

After transforming into a boss, you cannot pick up normal loot. At the end of the match, you can claim exclusive weapon charms and season-collection cosmetics. This mode does not affect the balance of standard extraction matches.

8. System-Level Optimizations

Warehouse Secondary Password — Adds a second-layer password to prevent accidental dismantling and theft of high-value equipment, fully resolving the "blade-account-destruction" problem.

Death Replay System — Replay your death from the killer's perspective to review positioning mistakes and identify suspicious behavior. Serves dual purposes: self-improvement and anti-cheat assistance.

Permanent Mobile Shooting Range — Enter the shooting range at any time outside of matches to test weapon mods and practice recoil control, no queue required.

Custom Room Mode — Supports 1v1 and multi-player team modes, compatible with all maps (including AZ3 Nuclear Power Plant). Items cannot be taken out of the match — purely for practice and competitive play.

Season Rank Reset — Full ladder reset with new S10-exclusive ranked rewards.

9. Anti-Cheat and Battle Pass

G.T.I. Security June Special Operation: Six measures to combat cheating, working in tandem with the Death Replay system to further purify the match environment.

S10 "Nuclear Fission" Battle Pass: The themed pass includes multiple legendary red skins and operator skins. Complete daily and weekly challenges during the season to unlock all rewards.

Conclusions

Season 10 "Nuclear Fission" is one of the most content-dense updates Delta Force: Hawk Ops has ever received. Liquid Nitrogen (Gabriel) fills a glaring need for a control-oriented Engineer with a versatile, high-skill-ceiling kit. The SVTH and RM277 weapons signal a deliberate power shift toward heavy calibers, rewarding precision and positioning over spray volume. The Dirge Nepal knife brings a premium close-quarters option with game-changing reach and damage. Whether you are here for the PvE boss hunts, the high-stakes extraction gameplay, or the large-scale Havoc Warfare, S10 has something substantial to offer.
