Knife Arena strips away everything except the knives. No guns. No abilities. Just you, your blade, and your throwing arm. I went in expecting a gimmick and came out 2 hours later with sore fingers and a newfound respect for knife physics.
December 2025 has been huge for this game. The “HUGE UPDATE” on Dec 19 added 2 new knives, a new Series Skin Case, and a new map. Then on Dec 26, another update dropped with a pixel-style map and 1v1 Ranked matchmaking announced as coming soon. Perfect time to jump in.
This is pure FPS combat distilled to its most satisfying form. Every kill feels earned because you had to calculate trajectory, lead your target, and actually land the throw. My first 20 minutes? Embarrassing. Couldn’t hit anything. But once it clicks? Incredibly satisfying.
Working Knife Arena Codes
The December 2025 updates brought new content and codes. Here’s everything that works right now:
| Code | Reward |
|---|---|
| freecase | Free Release Case (New!) |
| LAUNCH | Free Starter Knife |
| FPS | Bonus Coins |
The freecase code dropped with the updates. Grab it before it expires. The new Series Skin Case from the HUGE UPDATE has some sick skins, but you’ll need to grind or get lucky with codes for those.
The LAUNCH code is still the priority for new players. That starter knife is legitimately better than the default blade. Better throw speed, better damage. I played 5 matches with the default knife before realizing I was handicapping myself.
How to Redeem Codes
- Open Knife Arena and get into the main menu
- Click the Settings button (gear icon)
- Find the Codes button and click it
- Enter your code exactly as shown
- Hit Redeem and check your inventory
Copy paste these codes. LAUNCH and FPS are simple, but I’ve still managed to typo them. Don’t be me.
Why Knife Throwing Actually Matters
Here’s the thing. This isn’t just “throw knife at enemy.” Different knives have completely different stats.
Throw Speed determines how fast your knife travels. Faster knives are easier to land on moving targets. Slower knives require more prediction.
Damage is obvious. Higher damage means fewer throws to kill. Some knives one-shot, others take 2-3 hits.
Range affects how far your knife can travel before dropping. Short range knives force you into close quarters. Long range lets you snipe.
Trajectory is the big one. Some knives fly straight. Others arc. Learning your knife’s trajectory is the difference between hitting shots and throwing at walls.
The LAUNCH code knife has solid stats across the board. Not the best in any category, but no major weaknesses either. Perfect for learning the game.
Knife Throwing Tips
After whiffing probably 300+ throws, here’s what actually helped me improve.
Lead your targets. Way more than you think. Knives aren’t hitscan. They have travel time. Aim where your enemy will be, not where they are.
Learn one knife first. Don’t keep switching. Every knife has different trajectory and speed. Pick one and master it before experimenting.
Height matters. Throwing downhill is easier than uphill. The arc works with you instead of against you. Position accordingly.
Don’t spam throws. There’s a cooldown between throws. Missing and then panic throwing again just leaves you vulnerable. Take your time.
Watch the pros. Seriously. The skill ceiling in this game is insane. I watched someone land 15 consecutive headshots and questioned everything I knew about Roblox games.
Best Knives for Beginners
The LAUNCH code knife is your best friend starting out. Balanced stats mean you can learn fundamentals without fighting against your weapon.
Once you’ve got coins saved up (use the FPS code), look for knives with:
- Medium throw speed (not too fast, not too slow)
- Straight trajectory (arcing knives are harder to master)
- Decent range (gives you options)
Avoid the super fast knives early. They seem appealing but the timing is unforgiving. I bought a speed knife thinking it would make me better. It made me worse. Sold it after 3 matches.
The Coin Economy
Coins unlock new knives and cosmetics. You earn them through:
- Matches (slow but steady)
- Codes (FPS code gives you a nice boost)
- Kills (better players earn faster)
Save your coins for knife upgrades, not cosmetics. A better knife directly improves your gameplay. A cool skin just makes you look good while missing throws.
Where to Find New Codes
The game just launched, so expect more codes with:

Check the game’s Roblox page and any official social media. I’ll update this page when new codes drop.
