The Exterminator is one of the most sought-after classes in Deadly Delivery, mainly because of its flamethrower-based combat style and strong crowd control. However, unlocking it isn’t straightforward. The game doesn’t hand it to you through normal progression—you need to meet specific conditions, find the right NPC, and have enough money ready.
This guide explains exactly how the Exterminator unlock works, what you need before attempting it, and how players usually get it efficiently.

Basic Unlock Requirements
To unlock the Exterminator, you must:
- Reach Sublevel 25 or higher
- Find and rescue a special hostage NPC
- Return to the lobby and purchase the class
- Have roughly $180,000 available for the purchase (price may vary with updates)
Until you rescue the correct hostage, the class will not appear in the lobby at all.
Important Things to Know Before You Start
- The Exterminator hostage does not spawn before Sublevel 25
- The hostage spawn is random, not guaranteed every run
- The class is unlocked through rescue, not loot or drops
- A Bioscanner dramatically increases your chances by saving time
Many players fail simply because they search the wrong floors or don’t scan efficiently.
Best Preparation Setup
Before grinding for the unlock, make sure you have:
- Bioscanner (or a teammate who has one)
- Healing items (medkits or bandages)
- At least one stun or crowd-control item
- Enough money saved for the class purchase
- Optional: a team that can help you reach high floors faster
If you don’t have enough cash yet, farm money first—rescuing the hostage without being able to buy the class wastes a good opportunity.
Step-by-Step: How Players Usually Unlock Exterminator
1. Reach Sublevel 25+
You can either play normally until you get there or join experienced players who already run high floors. Many players use Discord groups to skip ahead faster.
2. Scan Every Floor Immediately
As soon as you enter a floor at Sublevel 25 or above, activate the Bioscanner.
- If the scanner shows no hostage, leave the floor immediately
- If it shows a hostage signal, follow it
This method is often called “scan and skip” and is the fastest way to find the Exterminator hostage.
3. Rescue the Hostage
Once you locate the hostage NPC:
- Clear nearby enemies first
- Interact with the hostage
- Escort them safely to the evacuation point
If the rescue completes successfully, the unlock condition is met.
4. Return to the Lobby and Buy the Class
After the run, go to the class selection menu in the lobby. The Exterminator should now be visible and purchasable.
Buy it to permanently unlock the class.
Recommended Team Setup (Optional but Faster)
If you’re running with others, this setup works well:
- Scanner user – finds hostages quickly
- Healer/support – keeps the escort alive
- Crowd control player – stuns enemies during rescue
- Fast mover – helps clear floors and move quickly
Solo is possible, but groups dramatically reduce the grind.
Common Mistakes to Avoid
- Searching floors below Sublevel 25
- Fully clearing floors before scanning
- Entering runs without enough money
- Ignoring crowd control during escort
- Assuming vaults or rare rooms guarantee the hostage (they don’t)
Most wasted hours come from checking the wrong floors or spending too long on empty ones.
Learning the Exterminator Class
Once unlocked, the Exterminator starts with a flamethrower and focuses on area damage.
Things to keep in mind:
- Ammo runs out quickly if you spray nonstop
- Best used against groups, not single targets
- Positioning matters—short range but high damage
Practice a few safer runs before taking it into high-risk floors.
Final Notes
Unlocking the Exterminator is more about efficiency than luck. If you consistently scan, skip empty floors, and focus only on Sublevel 25+, you’ll get it sooner or later. The Bioscanner alone can cut the grind time by hours.
If something doesn’t line up—price changes, class not appearing, or unusual behavior—it’s likely due to a recent update, so always double-check patch notes or community announcements.
