The Steel Fighters codes worth grabbing first are ULTRASECRETC3DE for a permanent +10% Cash boost, S3CRETC0DE for a permanent +10% Arena Damage boost, and AT0M3 for the Atom robot plus one Golden Die. Finish the tutorial in Roblox, then use the Codes machine beside Events near the Junkyard to redeem them. The table below covers all 12 codes, including timed potions and crafting resources. Claim the permanent rewards early, but save the temporary boosts for a session when you can actually use them.
What are the active Steel Fighters codes?
These 12 Steel Fighters codes provide permanent bonuses, a robot, currencies, and consumables. Enter each code exactly as written, especially the strings that mix letters with numbers.
| Code | Rewards |
|---|---|
| ULTRASECRETC3DE | Permanent +10% Cash boost |
| S3CRETC0DE | Permanent +10% Arena Damage boost |
| AT0M3 | One Atom robot and one Golden Die |
| RELEASE | Cash, Scrap, and 100 pass XP |
| STEELFIGHTERS | Cash |
| SCRAPKING | Scrap |
| DRONES | Cash and Scrap |
| TOSPACE | One 15-minute Money Potion and one 15-minute Luck Potion |
| LUCKY | One 30-minute Luck Potion and two rerolls |
| ARENA | One 30-minute Arena Potion and Cash |
| FREEDICE | Two Golden Dice |
| THANKYOU | One Golden Hammer, two Skip Tickets, and 150 pass XP |
Are any codes expired?
There are currently no expired Steel Fighters codes. Codes can stop working, so claim rewards you are ready to use rather than assuming every code will remain available indefinitely.
Each code can be claimed once per account. FREEDICE, for example, will not award another pair of Golden Dice if you enter it again after a successful redemption.

Which Steel Fighters codes should you redeem first?
The permanent boosts deserve priority because they have no 15-minute or 30-minute window to manage. ULTRASECRETC3DE improves Cash gains permanently, while S3CRETC0DE permanently increases Arena Damage. Redeem both as soon as you can access the machine.
Permanent boosts and Atom
After the two permanent bonuses, AT0M3 is the standout claim: it gives you Atom directly, alongside one Golden Die. That makes it the code to use when your immediate goal is adding a robot rather than collecting more currency.
Timed boosts
TOSPACE, LUCKY, and ARENA need more thought. TOSPACE provides two 15-minute potions, while LUCKY and ARENA each include a 30-minute boost. Redeem these when you are ready to use their effects, not while you are about to leave.
For ARENA, put your squad into the arena before claiming the code. You can then spend the boost window fighting instead of getting your team into position.
How do you redeem Steel Fighters codes?
The Codes machine arrived with Update 1, and you must finish the tutorial before using it. Its location is near the edge of the Junkyard, beside the Events machine.
Follow these steps to claim your rewards:
- Launch Steel Fighters and wait for your character to spawn.
- Complete the tutorial if this is your first visit.
- Walk to the Codes machine beside Events near the Junkyard.
- Press E on desktop, or tap the interaction prompt on mobile.
- Paste a code into the Type a Code Here field.
- Select Redeem.
- Repeat for your remaining codes, keeping timed boosts until you are ready.
The machine handles Steel Fighters codes specifically. A Steel Crossfire code will not redeem here. If that is the game you meant to open, use the Steel Crossfire codes guide instead.
How should you use the Cash and Scrap rewards?
Cash supports upgrades, while Scrap helps you build and improve robot parts. The important timing decision is rebirth: both Cash and Scrap reset to zero when you rebirth, so claiming a one-time currency reward immediately beforehand can waste anything you leave unspent.
If you are ready to rebirth, complete that reset before redeeming unused Cash and Scrap codes. If you are continuing your current run, spend the rewards on the progression available to you instead of leaving them untouched before a reset.
Which upgrades require rebirths?
Steel Fighters gates upgrades behind rebirth milestones. Use your current rebirth count to check which options are available before planning how to spend your Cash.
| Required rebirths | Available upgrades |
|---|---|
| 1 | Swift Steps, Cash Boost, Scrap Boost |
| 3 | Cash Boost II, Scrap Boost II, Big Backpack, Arena Cash Cap |
| 6 | Lucky Lever, Arena Power, Cash Boost III |
| 10 | Lucky Lever II, Arena Power II, Scrap Boost III |
The first upgrade tier requires 1 rebirth. A new account should therefore finish its early progression before treating code Cash as an immediate upgrade-shopping budget.
Why is a Steel Fighters code not working?
A typo is the first thing to check, particularly with AT0M3, S3CRETC0DE, and ULTRASECRETC3DE. These strings contain numbers that are easy to mistake for letters.
Work through this checklist before giving up on a code:
- Check the digits. AT0M3 uses a zero, and S3CRETC0DE uses both a three and a zero.
- Remove extra spaces. Keep the code free of spaces before or after the string.
- Finish the tutorial. The Codes machine is locked until you complete it.
- Check previous claims. A code already redeemed on your account will not pay out again.
- Consider expiry. If the spelling is correct and the code is unclaimed, it may have expired.
Copying ULTRASECRETC3DE directly is safer than typing it from memory. The exact spelling matters, including the final 3 in its secret-code wording.

Can you get another free robot without a code?
Steel Fighters offers a separate free-robot reward for liking the game on Roblox and joining the WeShowProjects group. After completing both requirements, confirm them at your base to claim the robot.
That base reward is separate from AT0M3, which grants Atom through the Codes machine. The like-and-join confirmation is not where you enter code strings.
Where can you find more Steel Fighters codes?
New Steel Fighters codes appear in the game's Discord server, and secret codes can also be found around the map. If your Roblox account is verified for chat, the Discord link is available at the bottom of the game's Roblox page.
The Codes machine remains the place to redeem those discoveries. You do not need to enter codes on another website or install a code-redeemer script to claim the rewards.
Once you have claimed Atom and the permanent boosts, browse our Roblox guide collection for code guides covering your next game.
