Delta Force AZ3 Keycard Rooms: Every Card's Cost vs Contents

🎯 The core idea

AZ3 has seven keycards worth knowing before you buy any of them, and their prices scale from roughly half a million to nearly six million in-game currency — the cheapest card unlocks a shortcut with zero loot inside, while the most expensive unlocks four servers, a computer case and a big safe. Buying a keycard is a bet: you're spending guaranteed currency now against loot you haven't seen yet, so knowing what's actually inside each locked room before you buy is what turns that bet into a plan.

• free costs nothing
• cheap small cost
• setup needs preparation
• grind pays off slowly
• skip the thing to stop doing

Railway Passage: the cheapest card, and the only one with no loot

The Railway Passage keycard is AZ3's cheapest at an average price of 550,000, and it is honest about what it's for: it doesn't unlock a loot room at all, just an access shortcut between the reactor area and the transport warehouse, sitting between the core area and the transport warehouse. If you're not planning to make that specific crossing repeatedly in a raid, this is the one card in the set to skip.

Accelerator Control Room and Totemac Data Center: the two data-heavy mid-tier cards

Accelerator Control Room, on the right-hand side of the map inside the Accelerator Research Institute (reached from the north entrance), is the more mysterious of the pair — it holds a combination lock the video's own creator admits not having decoded yet, alongside a large safe, loose loot spawns, and a drawer. If you know what the combination lock does, that's still an open question for the community.

Totemac Data Center, at the Old Academy of Sciences on the map's left-hand side (also from the north entrance), is simpler to evaluate: a computer, a computer case, and three servers, no safe. Between the two, Accelerator Control Room's safe plus loose spawns generally means more roll variance (it can whiff or hit big), while Totemac's three fixed servers are a steadier, more predictable haul.

Pressurized Water Reactor Server Room: the first six-figure-plus tier

Reached from the south entrance, this room contains three servers and a computer case like Totemac, but adds an extra side area with a computer bag and a suitcase — which is likely why its average price (1,123,450) sits noticeably above the two data-center cards. More container variety generally means more roll chances, and this room has the most container types of any AZ3 keycard room below the top tier.

Spent Fuel Plant Server Room: the lightest loot list at this price

This is the room to think hardest about before buying: at 1,327,220 average, it's priced above the Pressurized Water Reactor room despite holding less — just one server and one big safe, found in the Spent Fuel Processing Plant on the map's left side (north entrance). A big safe is a legitimate high-value container, but on raw container count this is the thinnest loot list of any card above Railway Passage, so its value depends heavily on what that one safe rolls.

The video doesn't explain why this card costs more than the Pressurized Water Reactor room despite fewer containers — average price in Delta Force reflects what other players are actually paying for the card itself (a tradeable item), which doesn't always track cleanly with the value of what's behind the door. Treat price and loot-worth as two separate questions.

Turbine Control Room: the balanced mid-to-high pick

South of the turbine hall, up a stairwell, Turbine Control Room holds two computer cases, a big safe, and loose loot spawns on the desks — three distinct container types plus open spawns, which is the widest spread of guaranteed containers on any card below the most expensive one. If you want a card that's likely to pay out something no matter how the safe and loose spawns roll, this is the strongest case for a "safe bet" pick in the upper-middle of the price range.

Reactor Master Control Core: the most expensive card, and the biggest room

At the top of the range sits Reactor Master Control Core, reached from the core reactor's left entrance all the way to the top: 5,755,030 average, more than four times the next card down. Inside: four servers, a computer case, and a big safe — the single largest guaranteed container count of any AZ3 keycard room. Its keycard also has 40 durability against the 20 durability on every other card in this list, meaning it can be used to open its door twice as many times before it breaks, relevant if you or your squad plan to return to this room across multiple raids.

Reading the cheapest-to-most-expensive order as a buying guide

1. Match your budget to container count, not just price rank grindSpent Fuel Plant Server Room breaks this pattern — it costs more than Pressurized Water Reactor Server Room while holding fewer containers, so don't assume price order always equals loot order. 1:47
2. Buy Reactor Master Control Core's card if you'll actually return to AZ3 setupIts 40 durability (double every other card here) means the steep price amortizes over two uses instead of one, which changes the math if you run AZ3 regularly. 3:05

How this guide was fact-checked

Every room name, location, container list and keycard price in this guide was read directly from GTAnt's AZ3 keycard walkthrough (3:22, published 2026-06-30) — the prices for Railway Passage (550,000), Pressurized Water Reactor Server Room (1,123,450), Spent Fuel Plant Server Room (1,327,220) and Reactor Master Control Core (5,755,030) are all read from the in-game keycard item screens captured on-screen, including exact durability values. Room contents for Accelerator Control Room, Totemac Data Center and Turbine Control Room are read directly from the presenter's narration while walking through each room. AZ3 is a Season 10/Meltdown-launch map, so it does not yet have a mature wiki entry on deltaforcetools.gg or the Fandom wiki at the time of writing — both were checked and neither returned a usable AZ3-specific keycard page, which is consistent with this being brand-new launch content rather than an oversight on this guide's part.

What this guide doesn't answer

This guide could not confirm the on-screen average price for Accelerator Control Room, Totemac Data Center or Turbine Control Room — the video's footage for those three rooms shows the room and its contents but cuts away before or after the keycard's own price screen, so this guide reports their contents and relative price-rank (from the video's stated cheapest-to-most-expensive order) without inventing specific numbers for them. It also doesn't explain what the combination lock inside Accelerator Control Room actually does, since the video's own creator says they haven't figured it out either — nor does it cover keycard locations for pickup or farming routes (a separate companion video by MuthaQuokka covers where to find and farm these cards, as opposed to what's behind their doors). It also doesn't cover AZ3's separate passkey/master-key system, if one exists beyond these seven individual room cards — this video only covers per-room keycards. Prices are account-specific averages that move with the in-game market, so treat the figures here as a snapshot from June 2026 rather than a fixed price list.
