KAT Codes (July 2026) — All Knife Ability Test Codes & Music IDs

Updated May 12, 2026 • By Earnaldo Team

Looking for KAT codes? Knife Ability Test (KAT) is one of the longest-running FPS knife combat games on Roblox, developed by Fierzaa. Players jump into fast-paced free-for-all arenas, grab knives with unique abilities, and fight to dominate the scoreboard. After being placed under review in August 2025, KAT made its full return on March 19, 2026, and the community has been growing steadily ever since. This guide covers everything you need to know about codes in KAT, including how to use Music ID codes with the Radio Gamepass.

Here is the short answer: KAT does not currently have a traditional code redemption system. There is no text box or menu in the game where you can enter promotional codes for free knives, coins, or cosmetics. We verified this directly in the live game (Place ID: 4592931260) and confirmed there is no code entry interface anywhere in the KAT menus as of July 2026.

However, KAT does support Music ID codes through its Radio Gamepass feature. If you purchase the Radio Gamepass with Robux, you can enter Roblox audio asset IDs to play custom music during matches. We cover that system in full detail below, along with popular Music IDs you can try, strategies for earning knives without codes, and tips that will sharpen your gameplay immediately.

All Active KAT Codes (July 2026)

KAT (Knife Ability Test) does not have a code redemption system as of July 2026. The developer Fierzaa has never implemented a promotional code UI in the game. No active reward codes exist for KAT at this time.

While there are no traditional reward codes, the game does support Music ID codes through the Radio Gamepass. This is the closest thing to a code entry system in KAT. Players who own the Radio Gamepass can enter Roblox audio asset IDs to play custom background music during matches. These are not promotional codes that grant items, but they do give you a way to personalize your gameplay experience.

Popular Music ID Codes for KAT Radio Gamepass

If you own the Radio Gamepass, you can enter these Roblox Music IDs into the radio player to jam out during KAT matches. These are some of the most popular audio tracks that players use. Keep in mind that Roblox updated its audio privacy policy in recent years, so only audio uploaded by verified accounts or the game developer may work reliably.

You can find thousands more Music IDs by browsing the Roblox audio library directly or searching community databases. Phonk, lo-fi, and EDM tracks tend to be the most popular choices among KAT players because they match the fast-paced energy of knife combat. Experiment with different genres to find what fits your playstyle.

How to Use Music ID Codes in KAT

The Radio Gamepass is the only code-like feature in KAT. Here is exactly how to set it up and start playing custom music during your matches.

1. Open Roblox and launch KAT (Knife Ability Test) from the game page (Place ID: 4592931260).
2. Open the in-game shop and purchase the Radio Gamepass with Robux. This is a one-time permanent unlock that carries over across all sessions.
3. Once the purchase is confirmed, join or start a match. You will see a radio icon appear on your screen.
4. Click the radio icon to open the music player interface. A text field will appear where you can enter a Roblox Audio Asset ID.
5. Paste or type a valid Music ID (such as the ones listed above) into the text field and press Play.
6. The selected track will play as background music during your match. You can change tracks at any time by entering a different Music ID.

The Radio Gamepass works in every KAT lobby and persists across sessions. Once you own it, you never need to purchase it again. The music you play is audible only to you and does not affect other players, so feel free to choose whatever tracks you enjoy without worrying about disrupting your lobby.

Why KAT Does Not Have Traditional Codes

Most popular Roblox games use a code system to reward players with free items, currency, or cosmetics. KAT takes a different approach. The developer Fierzaa designed the game around direct skill-based progression and in-game purchases rather than promotional code drops. Here is why this matters and what it means for your experience.

KAT rewards players through gameplay itself. Every kill earns coins, and those coins open doors to knife crates, shop items, and new abilities. The items you own in KAT reflect the time and effort you have invested in the game. For many competitive players, this skill-based economy feels more rewarding than redeeming a string of characters for a freebie.

The game also has a Robux shop where premium knives, effects, and gamepasses are available for direct purchase. Fierzaa monetizes through these transactions rather than using codes as a marketing or engagement tool. This is a common design choice among established Roblox games that have built steady audiences through gameplay quality rather than promotional mechanics.

It is worth noting that KAT was under review by Roblox from August 2025 through March 2026. The game returned on March 19, 2026, and the developer has been rolling out updates since. There is a chance that a code system could be introduced as part of future updates to re-engage the community and attract new players. We monitor KAT closely and will add codes to this page the moment they become available.

How to Get Free Knives in KAT Without Codes

Since KAT does not offer promotional codes, you need to rely on in-game methods to build your knife collection. These are the most effective strategies that experienced players use to earn items without spending Robux.

Earn Coins Through Kills and Wins

Every elimination in KAT awards you coins. The more kills you rack up per match, the faster your coin balance grows. Winning matches provides bonus coins on top of your kill earnings. Focus on consistent performance rather than occasional big games. A player who averages 8 to 10 kills per match will accumulate coins much faster than someone who plays passively and only gets 2 or 3 kills per round.

Open Knife Crates Strategically

KAT features multiple knife crates at different price points, each containing a pool of knives with varying rarities. Before spending your coins, check what each crate contains and what the drop rates look like. Some crates offer better odds on rare knives while others provide a wider selection of common items. Save your coins for the crate that has the best chance of giving you the knife or rarity tier you are targeting.

Take Advantage of Daily Rewards

KAT offers rewards for consistent play and daily logins. These bonuses are modest individually, but they compound over weeks and months. Make it a habit to log into KAT at least once per day to collect your daily reward, even if you do not have time for a full play session. Over time, these small bonuses add up to significant progress.

Trade with Other Players

The KAT trading system is one of the most powerful tools for building your collection. If you pull a rare knife from a crate that does not match your playstyle, you can trade it with another player for something you actually want. Trading removes the randomness of crate drops from the equation and lets you target specific items directly. Join KAT trading communities on Discord and social media to find the best deals and connect with active traders.

Level Up for Milestone Rewards

As you play KAT and gain experience, you unlock level-based rewards at certain milestones. These can include coins, knife skins, and other cosmetics. Playing consistently and performing well in matches is the fastest way to level up and unlock these milestone bonuses. The leveling system rewards long-term commitment to the game.

KAT Game Tips and Combat Strategies

Without codes to give you a head start, skill is the primary currency in KAT. These strategies will help you climb the leaderboard and earn coins at a faster rate.

Master Your Movement

KAT is a game where standing still means dying. The best players are constantly moving, jumping, and strafing to make themselves difficult targets. Use the environment to your advantage by jumping around corners, sliding behind cover, and using elevation changes to throw off opponents. Develop a habit of never running in a straight line when another player is within throwing range. Unpredictable movement is your strongest defensive tool.

Learn Every Knife Ability

Each knife in KAT has a unique special ability. Some throw explosive projectiles, others create area-of-effect blasts, and a few offer defensive shields or mobility boosts. Knowing what each knife does before you pick it up gives you a significant tactical advantage. When you grab a new knife mid-match, take a quick look at its ability description before engaging. Using the right ability at the right moment is often what separates top players from average ones.

Control Map Chokepoints

Every KAT map has high-traffic areas where players naturally converge. Learning these chokepoints and positioning yourself near them lets you catch opponents off guard. Camp near popular routes with a ranged knife ability, or use close-range knives in tight corridors where opponents have limited room to dodge. Map knowledge compounds over time, so pay attention to player flow patterns in each arena.

Practice Knife Throwing Accuracy

Many knives in KAT can be thrown at range, and landing a clean throw on a moving target is one of the most satisfying plays in the game. Spend time deliberately practicing ranged throws in every match. Aim slightly ahead of a moving target to account for travel time. Players who master knife throwing have a massive advantage because most opponents focus exclusively on melee combat and are caught off guard by a well-timed ranged attack.

Watch the Kill Feed

The kill feed in the top corner of your screen tells you who is killing whom and with what knife. Use this information to track which players are on kill streaks, what knives are being used, and where the action is concentrated on the map. If a player is dominating, consider targeting them specifically. Shutting down the lobby leader can shift the scoreboard in your favor and earns you more recognition among the other players.

All Expired KAT Codes

KAT has never had a traditional code redemption system, so there are no expired codes to document. The developer Fierzaa has not released any promotional codes for Knife Ability Test at any point during the game's history. This section is included for completeness and to confirm that no historical codes have been overlooked.

KAT Game History and Re-Release

KAT (Knife Ability Test) has been a staple of the Roblox FPS and combat genre since its launch. Developed by Fierzaa, the game accumulated hundreds of millions of visits and built a dedicated community of competitive knife combat enthusiasts. Its core gameplay loop of dropping into arenas, picking up ability-equipped knives, and battling in timed free-for-all rounds kept players coming back match after match.

In August 2025, KAT was placed under review by the Roblox platform. During the review period, the game was temporarily unavailable to players. This was a difficult time for the KAT community, as many players were unsure whether the game would return. Some moved to other combat games during this period, while dedicated fans waited for updates from the developer.

On March 19, 2026, KAT was officially re-released and made available to players once again. The game returned with its core features intact, and Fierzaa has been working on updates to re-engage the community and attract new players. The re-release has been well received, and the concurrent player count has been climbing steadily since the game came back online.

The re-release raises an interesting possibility regarding codes. Many Roblox developers introduce code systems when they want to boost engagement after a major update or relaunch. While Fierzaa has not announced any plans for a code system, the post-review period would be a logical time to introduce one as a way to reward returning players and welcome new ones. We will keep this page updated if the situation changes.

KAT vs. Similar Roblox Combat Games

KAT competes with several other popular combat and FPS games on Roblox. Understanding how it stacks up can help you decide whether KAT is the right fit for your playstyle.

KAT vs. Murder Mystery 2: Both games involve knives, but they play very differently. Murder Mystery 2 is a social deduction game where one player is the murderer. KAT is pure free-for-all combat where everyone fights simultaneously. MM2 has historically offered promotional codes, while KAT has never had them. Choose KAT if you want raw, fast-paced PvP action. Choose MM2 if you enjoy tension and mystery.

KAT vs. Blade Ball: Blade Ball focuses on deflecting a deadly projectile rather than direct knife combat. Blade Ball does have an active code system with regular drops. KAT offers more traditional FPS-style combat with unique knife abilities. Both are strong choices for competitive Roblox players, and many players enjoy switching between the two.

Frequently Asked Questions

About KAT (Knife Ability Test) on Roblox

KAT was created by Fierzaa and stands as one of the most enduring PvP games on the Roblox platform. The game drops players into arena-style maps where the objective is straightforward: pick up knives, use their unique abilities, and eliminate other players to score the most points before time expires. Each match is a timed free-for-all, and the player with the highest kill count at the end wins.

What separates KAT from the competition is its knife ability system. Every knife in the game comes with a distinct special ability, ranging from explosive throws and teleportation dashes to shield deployments and area-of-effect blasts. This adds a layer of strategic depth on top of raw aiming and movement skill. Choosing when and how to deploy your knife's ability can completely turn around a losing fight or secure a crucial kill streak.

The game features a wide variety of maps with different layouts, sizes, and vertical complexity. Compact maps favor aggressive close-range play, while open arenas reward players with strong throwing accuracy. Learning the flow of each map and adapting your strategy accordingly is one of the key skills that separates casual players from leaderboard regulars.

KAT has accumulated hundreds of millions of visits on Roblox and maintains an active player base. Its blend of accessible mechanics, deep customization through the knife collection system, and a high skill ceiling makes it appealing to both newcomers who want quick action and veterans who want to compete at the highest level. With the game's return in March 2026, the KAT community is experiencing a resurgence, and the future looks promising for one of Roblox's longest-running combat titles.
