Delta Force AZ3 Map Guide: Zones, Radiation, and How to Survive
AZ3 drops you into a nuclear plant that's actively falling apart, and most squads walk in without a plan for the radiation, the reactor event, or the boss waiting in the core. That's how good loot runs turn into wipes. We've broken down every system on the map so you know exactly what you're walking into before you drop.
What Is AZ3?
AZ3, officially called Nuclear Power Plant, launched with Delta Force Season 10 Meltdown on June 30, 2026, as confirmed in Team Jade's official season announcement. It's the first new Operations map added since Tide Prison, and it's built around a live reactor crisis rather than a static layout. According to the developers at Team Jade, the goal was to make the map itself react to what players do during a run: firefights, searching, and pushing objectives can all trigger explosions and leaks that change the space as the match plays out, a design choice Game Director Shadow Guo detailed to Xbox Wire ahead of launch.
If you're still working through the rest of the Meltdown season guide, AZ3 is the centerpiece addition, alongside the new operator N-Two.
AZ3 Map Layout
AZ3 splits into three main sections, separated by water and railway tracks:
West Zone - Home to the Spent Fuel Processing Plant and the old Academy of Sciences. Lower player traffic on average, with solid early-game loot.
East Zone - Covers the Research Institute, the Pressurized Water Reactor building, and the wastewater storage area in the northeast corner.
Core Area - The central reactor complex, including the sarcophagus dome and turbine hall. This holds the most valuable loot on the map and doubles as the boss zone.
Spawn and extraction work on opposite ends, similar to Zero Dam. If you spawn West, you'll typically extract East, and vice versa. A number of buildings hide large underground sections, so don't assume the surface layout is the whole picture.
The Radiation System
Radiation is the mechanic that makes AZ3 different from every other Operations map. Certain zones and containers raise your radiation level the longer you stay near them, and higher exposure brings real consequences: blurred vision at first, then reduced max health if you don't decontaminate in time.
Guides currently disagree on the exact number of exposure stages, with some describing three tiers and others describing four, so treat the specific tier count as unconfirmed until it's verified against official patch notes. What's consistent across sources is the core loop: a high-grade gas mask and anti-radiation medication are required gear before you push into deep radiation zones, and decontamination stations are placed throughout each sector to let you clear exposure mid-run. Standard painkillers won't touch radiation damage, so don't rely on your usual medkit loadout.
Outside of matches, Team Jade added a Decontamination Chamber system to the Black Site specifically for Meltdown, which raises your radiation tolerance and speeds up natural decay as you level it up. If you're still dialing in your gear for AZ3 runs, our best loadouts breakdown covers armor and consumable picks that hold up in radiation zones.
The Reactor Shutdown Event
Partway through a match, the reactor's power level starts climbing, visible on the scoreboard for the whole lobby. That triggers a decision point: push into the control room and attempt the shutdown, or avoid it and deal with whatever comes next.
A successful shutdown rewards every participating player with bonus loot. Failing or ignoring the event triggers a blast countdown that pushes every surviving squad into a shrinking, increasingly irradiated safe zone, so a botched shutdown doesn't just cost your squad the reward, it raises the stakes for everyone still on the map. It's one of the more interesting objectives Delta Force has added to Operations, because it forces a genuine risk decision instead of just marking a point of interest to loot.
H1000 Boss Fight
Officially named Neural Device Agent-H1000 in Team Jade's patch notes, H1000 is AZ3's new high-tier threat, stationed in the underground core facility. Unlike the guard-style bosses on other maps, H1000 is described by the developers as fast, lethal, and unpredictable, tied to the map's Neural Device systems rather than pure firepower, which changes how you need to approach the fight compared to bosses like the ones on Space City or Brakkesh.
Bring full armor and a real medical loadout before engaging. Multiple community guides report that a successful reactor shutdown weakens H1000 for squads who fight it afterward, though that specific detail hasn't shown up in official patch notes yet, so treat it as a helpful tip rather than a guaranteed mechanic. If your gear isn't there yet, our best weapons guide and PvP weapons guide are good starting points before you attempt this fight.
Keycards and Pass Keys
AZ3 removed the old system where you could buy a keycard directly from the in-game store. Instead, cards now spawn at fixed points across specific buildings, split roughly evenly between the West, East, and Core zones so you have a shot at finding one no matter where you land.
Pass keys work differently. They're found lying around the map, and they beep audibly, so following the sound is the fastest way to track one down. Once picked up, a scanner points you to the exact room it opens, and unlike keycards, a pass key only works on that one door. Reported keycard counts vary across sources right now, so don't plan a route around a specific total until that number is confirmed officially.
Extraction Points
Extraction on AZ3 mirrors the pressure of the reactor event. AZ3 only has two extraction points active at any time, fewer than most other Operations maps, which naturally funnels players toward the same chokepoints late in a run. If you're carrying a full bag, plan your exit early rather than waiting until the last few minutes.
Team Jade has also continued adjusting AZ3 after launch. A July 2026 patch reduced the radiation range around the reactor core during the Emergency Shutdown flagship mission and added an extra decontamination room near the top level of the reactor, based on the official Steam patch notes. If you played AZ3 in its first week and found the core area brutal, it's worth another look now that it's been tuned.
Why AZ3 Plays Differently From Other Operations Maps
Most of what makes AZ3 stand out comes straight from how Team Jade built it. Game Director Shadow Guo has described the map as intentionally reactive rather than static: the reactor's status is visible in real time throughout a match, so players can always gauge how close a run is to spiraling out of control. That's a deliberate departure from the fixed-stage design of earlier maps like Layali Grove or Brakkesh, where the environment itself doesn't shift based on what your squad does.
The visual design leans into that idea too. Half the map is an open, rusted-out scrapyard, and the other half is the decommissioned plant itself, contaminated water and all. It's meant to feel like the aftermath of Haavk's failed projects, in contrast to the more polished tech seen on Space City. If you're playing on console and want to know how AZ3 performs there, check our console performance guide for platform-specific notes.
Once you understand the radiation loop, the reactor event, and how H1000 fits into both, AZ3 stops feeling chaotic and starts feeling like the most rewarding map currently in Operations.

Key Takeaways
AZ3 (Nuclear Power Plant) launched with Season 10 Meltdown on June 30, 2026, the first new Operations map since Tide Prison.
The map splits into West, East, and Core zones, with spawn and extraction on opposite ends.
Radiation exposure requires a gas mask and anti-radiation medication; decontamination stations clear exposure mid-run.
The reactor shutdown event is a genuine risk decision that rewards loot but can spread radiation if handled poorly.
H1000 is the map's new boss, located in the core facility, and leans on speed over raw guard-style tankiness.
Keycards now spawn in buildings instead of the in-game store; pass keys are single-use and locate themselves by sound.
Only two extraction points stay active at a time, so plan your exit early rather than waiting for the final stretch.
Team Jade has already patched AZ3 once since launch, reducing core-area radiation and adding a new decontamination room.
FAQ
What is AZ3 in Delta Force?
AZ3 is the Nuclear Power Plant map added in Delta Force Season 10 Meltdown, which launched June 30, 2026. It's an Operations map built around a live reactor crisis, radiation zones, and a new boss called H1000.
How big is the AZ3 map?
AZ3 is one of the largest Operations maps released so far, combining surface and underground sections across West, East, and Core zones. Exact size comparisons to older maps vary by source, so treat any specific multiplier as a rough estimate rather than a confirmed figure.
What gear do I need for AZ3's radiation zones?
You'll want a high-grade gas mask and anti-radiation medication before entering deep radiation areas. Standard painkillers don't reduce radiation damage, so pack meds specifically meant for it.
What happens if I trigger the reactor shutdown event?
A successful shutdown gives every participating player bonus loot. A failed or ignored shutdown triggers a blast countdown that forces every surviving squad into a shrinking, higher-radiation safe zone.
Where do I find H1000?
H1000 is located in the underground core facility at the center of AZ3. It's tied to the map's reactor systems and relies more on speed than the guard-style bosses on other maps.
How do keycards work on AZ3?
Keycards no longer come from the in-game store. Instead, they spawn at fixed points inside specific buildings across the West, East, and Core zones.
What's the difference between keycards and pass keys?
Keycards can open multiple doors and are found at fixed building locations. Pass keys are single-use, located by an audible beeping sound, and only work on the one door they're tied to.
How many extraction points does AZ3 have?
AZ3 has just two active extraction points, fewer than most other Operations maps, which puts more pressure on route planning late in a match.
Is AZ3 available in every difficulty mode?
AZ3 runs across the standard Operations difficulty tiers, giving both newer and more experienced squads a way to learn the map's systems before pushing into higher-risk runs.
Why does AZ3 feel different from other Delta Force maps?
AZ3 was designed to react to player behavior in real time, with visible reactor status and environmental changes that respond to firefights and searching. Earlier maps like Layali Grove and Brakkesh use a more fixed, static layout by comparison.
