The FOB Vendor in MW4 DMZ opens at DMZ Level 5 and sells ready-to-use weapons and gear for DMZ Cash. Stock rotates once a day, and every purchase comes out of the same Bank that pays for Operator rescues, Gunsmith builds and FOB upgrades. That shared wallet is why every Vendor buy needs a reason. The best spends are Secure Slot backpacks and gear you cannot print yet. Most weapons only make sense in a few specific situations.
How the FOB Vendor Works
Check these rules before you spend anything, because they decide what a purchase is worth.
- Unlock: DMZ Level 5. A Vendor Unlocked banner appears at the FOB, and you can open it at the station or from the side menu.
- Layout: a Weapons column and a Gear column, with a Resets In timer in the top left counting down to the next daily rotation.
- Payment: cash comes straight from your Bank. Offers you cannot afford show Insufficient Funds.
- Delivery: every purchase goes to your Stash. Equip it from Stash/Loadout before you deploy.
- Locked slots: some offers read “Unlocks via DMZ Level or printed upgrades” until you reach the right level or print the Vendor upgrade.
- Squad stock: your Vendor screen can differ from a teammate’s, so compare before one of you buys for the group.
Anything you buy is lost on a failed exfil like the rest of your loadout. Only items sitting in a Secure Slot come home when a run goes wrong.
Vendor Prices Seen So Far
Prices belong to the roll they appeared in, so read each row as a benchmark for that item type.
| Offer | Rarity | Price | What You Get |
| Large Backpack | Legendary | $50,000 | MAX 200 capacity, 1 weapon slot, 2 Secure Slots |
| Small Secure Backpack | Epic | $25,000 | 3 Secure Slots |
| Medium Scavenger Backpack | Epic | $25,000 | 2 Secure Slots, extra Resource capacity |
| Mosin-Nagant | Rare | $32,750 | Prebuilt rifle with attachments fitted |
| Kastov 762 | Legendary | $126,250 | Prebuilt assault rifle with attachments fitted |
Gear offers have ranged from about $1,000 to $50,000.
Secure Slot Backpacks: The Strongest Early Buy
A Secure Slot is the one documented way to protect loot when you die. Early on, the Vendor is also the quickest way to get a pack with two or three of them. The Medium Backpack prints from the start for 50 Synthetics and 5 Rigid Synthetics, but it has only one.
- Small Secure Backpack: the most Secure Slots of any pack seen at the Vendor. It suits runs where you only care about a few high-value items, such as Legendary ingredients, keys or a Weapon Manual.
- Medium Scavenger Backpack: one fewer Secure Slot than the Small Secure Backpack, with more room for crafting Resources. It fits Resource farming runs for FOB upgrades.
- Large Backpack: four times the room of the starting Basic Pack, plus a weapon slot. It pays off on long loot routes where you plan to fill the bag.
The Large Backpack also turns up as a DMZ Level 34 reward and as a printer recipe from the Hornet’s Nest 1/2 Orders page. If you are close to either, that cash can go somewhere else.
Gear You Cannot Print Yet
The Vendor fills gaps in your recipe list. A vest, Gas Mask or Field Upgrade you have no recipe for can justify the cash, especially before a Lieutenant fight or a push toward the reactor. If the item already sits in your 3D Printer, compare the Resources it costs with the Vendor price before you pay.
| Item | How You Get It Without the Vendor | Vendor Buy Worth It? |
| Small Backpack | Starter recipe: 25 Synthetics, 25 Metals | No |
| 1-Plate Armor Vest | Starter recipe: 25 Synthetics, 25 Metals | No |
| 2-Plate Armor Vest | Starter recipe: 50 Synthetics, 5 Reactive Metals | Only when it rolls and you are short on Reactive Metals |
| 3-Plate Armor Vest | DMZ Level 37 reward or a recipe from DMZ Orders | Yes, if it rolls before you have the recipe |
| Large Backpack | DMZ Level 34 reward or the Hornet’s Nest 1/2 recipe | Yes, if both routes are still far off |
When a Vendor Weapon Beats the Gunsmith
Vendor guns arrive fully built and land in your Stash. You can then change them at the Gunsmith like any looted gun. They are expensive, though. A base M4 at the Gunsmith costs about 5,000 DMZ Cash, and a five-attachment M4 build comes to 99,987 DMZ Cash. Both sit below the Legendary Kastov 762 listed above
A Vendor weapon makes sense in three cases:
- The Gunsmith is still locked. It opens at DMZ Level 10, so the Vendor is the only cash route to a built gun between Levels 5 and 10.
- You have no Weapon Manual for that gun. The Gunsmith only builds weapons whose Manual you have extracted. A gun you buy or loot is a single copy, and losing it means losing access again.
- You are on the Worth Every Penny Order. The Grid 1/2 page asks you to buy a weapon from the Vendor, then get 50 kills with a Rare or better weapon. A cheaper Rare roll clears both tasks, and the page reward adds 20,000 DMZ Cash and a Triage Kit, plus a 3-Plate Armor Vest reward.
Weapon level matters too, because Gunsmith attachments unlock as a gun levels up. That progress is shared between Multiplayer and DMZ, and Shared Attachments unlock once for every compatible weapon. If you level a gun in a Bot Lobby MW4 match before taking it into Hajin, every attachment it unlocks there is ready at the DMZ Gunsmith. Weapon levels from a cheap Bot Lobby MW4 session carry over like any other Multiplayer levels, so with the Weapon Manual extracted you can build that gun yourself instead of waiting for it to roll at the Vendor. Multiplayer XP does not raise your DMZ Level, so Vendor slots and FOB station gates still need XP earned in DMZ.
What to Leave on the Shelf
- Your rescue fund. An eliminated Operator goes MIA and cannot deploy until you pay to recover them. The price climbs with their Trait Points, and they come back without gear, so keep that amount in the Bank.
- Anything you print for Resources only. Bandages, the Small Backpack and the 1-Plate Armor Vest cost no cash at the 3D Printer.
- Pricey guns for low-stakes runs. A $100,000 rifle disappears on death just like a free one. The Free Loadout covers practice runs, and you keep it if you exfil.
- Buys that block a needed upgrade. Your Bank starts capped at 100,000, and cash above the cap is not banked. Bank Upgrade I costs 20,000 and lifts the cap to 250,000, so it often beats an optional Vendor buy when you are near the limit.
Getting More Vendor Offers
The Vendor starts with a short list and grows with your DMZ Level, and higher levels also bring higher-level gear.
- DMZ Level 18: one more weapon offer.
- DMZ Level 32: four more item offers.
- Vendor Item Upgrade I: printed at the 3D Printer for 20 Electronic Sensors, 10 CPU, 10 Printed Circuit Board and 2 Prototype RF Module. It appears after you build Bank Upgrade II. Prototype RF Modules are Legendary ingredients, so put any you find in a Secure Slot.
- Season 1 BlackCell: one extra weapon and up to four Equipment offers at the Vendor, bought with DMZ Cash.
On November 5, the Season 1 update also refreshed FOB vendors, recipes and assembly requirements to match current items and crafting rules.
A Quick Daily Vendor Check
- Open the Vendor after the Resets In timer runs out and read both columns.
- Cross off anything your 3D Printer or Gunsmith can already make.
- Set aside one Operator rescue in the Bank.
- Buy only what covers a gap for your next few deployments.
Secure Slot backpacks and gear you have no recipe for are where Vendor cash goes furthest. Prebuilt rifles are worth the price only when the Gunsmith cannot build that gun for you. Everything else can wait for tomorrow’s rotation.
