Combat Arena is an arcade FPS that skips the slow build-up entirely. Matches throw you into arenas set in locations around the world — free-for-all races to 75 kills or team deathmatch — where movement and quick scoping matter more than camping a corner. You earn Coins for every performance, spend them on new weapons, and chase the streaks that unlock heavy abilities like airstrikes. The game is currently running its Halloween presentation, pumpkin icon and all.
Codes here pay out in crates rather than currency. The two working codes below open a Luxury Crate and a Primordial Crate, each packed with weapon skins you would otherwise be saving Coins and grinding matches to reach. One catch: Combat Arena makes you earn the right to redeem, so read the steps below before hunting for a code box that is not there yet.
All New Combat Arena Codes
- DUELS: Luxury Crate (==NEW==)
- JUSTFORFUN: Primordial Crate
Two crates may not look like much of a list, but crate codes are this game’s whole pattern — it has never run more than a couple at a time, and the skins inside a Primordial Crate are among the rarest the game gives away. Claim both while they are live.
Expired Combat Arena Codes
The arena’s trophy cabinet of dead codes — nine former rewards that no longer open anything:
- THANKYOU
- HOLIDAY2025
- ATRIPLE
- BOUNTY
- 300KF
- STREETS
- 1K
- GENEROSITY
- HAL9000
How to Redeem Combat Arena Codes
- Launch Combat Arena on Roblox.
- First, unlock code entry: reach 40 kills, win a match, and complete the tutorial. The Social Codes box stays locked until all three are done — if restarting the game after your 40 kills lets you skip the tutorial, that works too.
- Click the Rewards icon at the bottom of the screen.
- Type a code into the Social Codes text box.
- Press Claim and your crate will be added, ready to open.
How to Get More Combat Arena Codes
Atomic Horizon announces new codes through the game’s Roblox page and its X account, @PlayCombatArena, usually when an update or a seasonal event lands — the Halloween period brought the current set. There is no regular schedule, and codes have historically been one or two at a time, so catching an announcement early matters.
Save this page in your bookmarks and give it a quick check whenever a new update drops — confirmed codes replace the old ones here as soon as they are verified.
Why Are My Combat Arena Codes Not Working?
Double-Check for Typos: Codes are case-sensitive and several are lookalikes — THANKYOU and the retired holiday variant differ by a whole word, and 300KF is easy to mistype as 300K. Enter the code exactly as printed, with no extra spaces at either end.
The Code Has Expired: Crate codes rotate out when events end — HOLIDAY2025 and its nine companions all worked once. If a code fails with your spelling confirmed, it has almost certainly joined the expired list.
You Have Not Unlocked Code Entry Yet: This catches more players than typos do. Combat Arena will not even show you a working code box until you have 40 kills, a match win, and the tutorial behind you. If the Social Codes field will not accept input, play a few more matches first — the requirement is account progression, not a bug.

Conclusion
DUELS and JUSTFORFUN are both live in Combat Arena, and two free crates — one of them Primordial — are worth the small grind to unlock code entry. Put in the 40 kills, claim your crates, and may the skins be ever in your favour.
