🎯 The core idea
Season 10 (Meltdown) is Delta Force's biggest update of the year: a new Engineer operator, new weapons and attachments, a radioactive Operations map, a new Warfare map, a new transport helicopter, three new game modes, and a Rainbow Six Siege crossover. This breakdown is sourced from a preview built on China's pre-launch test server, published six days before the global June 30, 2026 release — several exact numbers changed between this recording and launch, and that's called out wherever it matters.
- free costs nothing
- cheap small cost
- setup needs preparation
- grind pays off slowly
- skip the thing to stop doing
New operator: N2 (Gabriel Mercier), an ice-based Engineer
N2's whole kit revolves around cryogenic crowd control: Frostbite (a passive that builds hypothermia and eventually freezes a target), a Homing Stun Grenade, Cryo-Flask, and his Frost Launcher ultimate. Two details worth knowing that this test-server footage caught: freezing an enemy with Cryo-Flask or the ultimate reveals them through walls for a short time, and N2 is completely immune to his own freezing effects, so you can walk through your own ice zone without penalty. In Warfare, his passive instead reduces enemy vehicle handling rather than fracture resistance. For the full ability breakdown, including exact numbers and counters, see this catalogue's dedicated N2 operator guide.
New weapons: SVCH, RM277, and two attachments that change how a gun plays
The SVCH marksman rifle looks unremarkable in semi-auto, but its special attachment converts it into a fully automatic rifle at an incredible 760 rounds per minute, with a dual-magazine system that auto-swaps once the first 20-round mag empties. It launched with slightly lower stats than the test build shown here — base damage and armor penetration were each reduced by one during testing, from 48/47 down to 47/46 — but it's still described as a near straight upgrade over the M14. The RM277 is a slower-firing alternative to the M7 (roughly 100 RPM slower) that trades fire rate for higher damage and armor penetration (41/42 versus the M7's 38/40), and it's the rare weapon that can equip both a stock and a cheek pad at once for extra recoil control.
The compound bow also gets a new HVK attachment that loads six arrows at once, a straightforward fire-rate buff for players who've already learned the weapon's normal reload rhythm.
Ammo and armor changes
The new CT ammo (9x19mm and .45 ACP) was nerfed before launch: it can no longer be stored in your safe box, its bonus damage only applies to limbs rather than all unarmored body parts, and it now increases both recoil axes and ADS spread — a real, if narrower, tool rather than the strong pick it was on the test server. The 6.8x51mm polymer ammo lost its old 5% damage penalty but keeps a 10% armor penetration penalty, so it's a minor buff rather than a replacement for standard 6.8 rounds. Two new armor sets (a tier 4 and a tier 5 helmet-and-armor combo) appeared in the test server's firing range but weren't yet tied to a confirmed source at recording time — likely a season event reward. None of these ammo or armor numbers come from an official patch-notes document; they're read directly off the test-server client, so treat them the way you'd treat any pre-launch preview of what's new rather than a published patch-notes changelog.
AZ3 (Nuclear Power Plant): puzzle safes and a real radiation system
The old free safe is replaced by seven interactive puzzle safes scattered across the map, split between a wire-matching puzzle and a memory-sequence puzzle. Radiation leak zones spawn randomly and are marked with a special icon; going from zero radiation to level four takes roughly 3 minutes of continuous exposure, and certain rooms can become contaminated mid-match without warning, which is what the Geiger counter's clicking is for.
This guide only summarizes the radiation and decontamination system at a high level. For the full mechanic — exact effects at each of the four radiation levels, decontamination chamber locations, and how the sprinkler-truck NPC and vehicle work — see this catalogue's dedicated AZ3 radiation survival and decontamination guide.
AZ3's key system also changed: purple, gold and red keycards now open purple, gold and red rooms respectively, with gold and red rooms guaranteeing at least one safe. Opening a purple or gold room can sometimes reward a higher-tier key, so one key can chain into up to three rooms — though spawns are randomized and not every key room is guaranteed to be reachable in a given match. For the full cost-versus-contents breakdown of each key tier, see this catalogue's AZ3 keycard rooms guide.
New Warfare map: Coliseum
The CSV-35: a new transport helicopter, plus a faster-firing AA weapon
The CSV-35 is a tiltrotor aircraft — vertical takeoff and landing combined with fixed-wing flight speed — built to move a squad across the map quickly while still carrying modifiable weapon systems for real firepower. It's described as carrying up to six players at once. It arrives alongside a new anti-air weapon with a noticeably faster rate of fire, which exists specifically to give ground teams a way to answer it and other aircraft. As of this recording, no dedicated CSV-35 tutorial video existed in English; this breakdown is the most detailed available source on it prior to global launch.
Three new game modes
Cosmetics: Battle Pass, a new melee weapon, and the Rainbow Six Siege crossover
The Season 10 Battle Pass's level-80 reward is a wild-west-themed skin for Tempest — a divisive choice by the video's own account, though it lines up with Tempest's backstory before joining GTI. A new melee weapon, Elegy (Raice's signature weapon), costs 5,220 Delta tickets, and the next AKM Mandelbrick skin arrives without any accompanying weapon buff.
The Rainbow Six Siege collaboration brings three operator skins — Vigil for Knox, Monty for Syniva, and Doc for Stinger — with two unlockable free through in-game challenges and the third purchasable for roughly 2,500 Delta tickets. Seven weapons also receive Siege's "Black Ice" skins, split across two paid bundles plus one free MP5 skin obtainable just by logging in on July 10th, and the collab closes out with an interactive R6 drone collectible of unconfirmed rarity.
Security and quality-of-life changes
Starting in Season 10, players compensated for gear lost to cheaters receive Tekniq Alloy equal to the item's value rather than the items themselves. A new anti-cheat review program lets qualified players review flagged gameplay clips on the Chinese server, requiring reviewers to maintain over 60% accuracy to stay eligible — it's in beta and not yet confirmed for global release. The video also mentions a larger new game mode teased for later testing, with no further detail available at recording time.
If you searched something like "delta force whats new 2026" and just want the headline additions, the section titles above are ordered roughly in the same sequence the source video covers them, from the new operator through to the security changes at the end.
How this guide was fact-checked
This guide is sourced from a single video — Dash's "Everything Coming in Delta Force Season 10" (29:15, published 2026-06-24) — built entirely on footage from China's pre-launch test server, six days before Season 10: Meltdown's global release on June 30, 2026. The video itself flags several numbers as provisional (the SVCH's damage stats, N2's Homing Stun Grenade damage, the two new armor sets' source), and where it does, this guide preserves that uncertainty rather than stating a single final number. The CSV-35 helicopter's tiltrotor design and troop-carrying role were independently cross-checked against Overgear's Season 10 overview, which confirmed the same vehicle description post-launch. Where this guide's summaries of N2's kit, AZ3's radiation system, or AZ3's key tiers overlap with this catalogue's dedicated guides on those topics, those dedicated guides are the more current, single-source-of-truth reference — this guide exists to cover the season as a whole, with the CSV-35 helicopter as its most detailed contribution, since no other English-language source focused on that vehicle at the time of research.
What this guide doesn't answer
This guide doesn't give a full map layout, loot routes, or Easter-egg breakdown for AZ3 or Coliseum — the source video explicitly defers both to future dedicated videos once the global test server opened, and this catalogue's own AZ3 guides cover keycard rooms and radiation survival in depth instead. It doesn't cover exact CSV-35 handling stats (health, seat-by-seat weapon positions, top speed) since the source video only shows it in brief flight, not a full vehicle breakdown. It also doesn't confirm final numbers for anything the source itself labeled provisional — treat the SVCH, N2's utility damage, and the two unclaimed armor sets as needing a post-launch recheck if you're relying on exact values rather than the general shape of the change.
