What Is KAT (Knife Ability Test)?
KAT stands for Knife Ability Test. It is a fast-paced PvP fighting game on Roblox created by developer Fierzaa. The game launched under Place ID 4592931260 and quickly grew into one of the platform's top competitive experiences. At its peak, KAT regularly pulled 30,000 or more concurrent players. Even after the 2025 review period that temporarily removed it from Roblox, the game bounced back to a consistent 10,000 to 20,000 concurrent players within weeks of its March 2026 re-release.
The premise is straightforward. Each round, one player receives a knife. That player must eliminate the other players by throwing the knife or attacking in melee range. Everyone else has to survive. The last player standing or the knife holder who eliminates the entire lobby wins the round and earns coins. Those coins go toward unlocking new knife skins, kill effects, and other cosmetic items that make your gameplay stand out.
KAT sits in the PvP and fighting genre alongside games like Blade Ball and Murder Mystery 2, but it differentiates itself with a physics-based knife throwing system that rewards mechanical skill over randomness. The arc-based throwing mechanic means there is a genuine skill ceiling. Players who invest time learning trajectories and prediction will consistently outperform newer opponents.
How KAT Works: Core Gameplay in 2026
Understanding the round structure is critical before diving into strategies. Every KAT round follows the same sequence, and knowing exactly what to expect gives you a significant edge over players who jump in without preparation.
Round Structure
- All players spawn in the arena. The server randomly selects one player to be the knife holder for that round.
- The knife holder receives their equipped knife skin. A countdown begins, and the round starts. All other players are unarmed runners.
- The knife holder hunts down runners using melee attacks (close range) or thrown knife attacks (mid to long range). Each thrown knife follows an arc trajectory affected by distance.
- Runners must dodge, use obstacles for cover, and stay alive. They cannot fight back directly. Movement, positioning, and map awareness are their only tools.
- The round ends when the knife holder eliminates all runners, or when the timer expires. If the timer runs out, the surviving runners win.
- Coins are awarded based on performance. The knife holder earns coins per elimination, and surviving runners earn coins for lasting through the round.
Coin Economy
Coins are the primary in-game currency. You earn them by winning rounds, getting eliminations as the knife holder, and surviving as a runner. The earning rate without any boosts averages around 15 to 30 coins per round depending on performance. With the VIP game pass (95 Robux), that rate doubles to 30 to 60 coins per round, which adds up substantially over extended play sessions.
Coins are used exclusively for unlocking knife skins from the in-game shop. Some of the rarest skins cost upward of 5,000 coins, which means even with VIP, you are looking at 80 to 160 rounds of strong performance to unlock a single high-tier skin. This grind is part of what keeps KAT's long-term player retention so strong.
Winning Strategies & Advanced Tips for 2026
KAT rewards players who understand both the mechanical and psychological sides of PvP combat. These strategies come from analyzing high-level KAT gameplay from creators like Tanqr and Sketch, who have produced some of the most-watched KAT content on YouTube.
As the Knife Holder
Master the arc. The single most important skill in KAT is understanding knife trajectory. When you throw a knife, it does not travel in a straight line. It follows a parabolic arc, dropping slightly over distance. For targets within 15 to 20 studs, aim directly at them. For targets 30 studs or more away, aim slightly above their head to compensate for the drop. This difference between hitting and missing at range separates average players from dominant ones.
Predict movement, do not chase the cursor. New players throw the knife at where the opponent is. Experienced players throw it at where the opponent will be. Watch runners for 1 to 2 seconds before throwing. Most players run in predictable patterns, especially when panicking. Throw to intercept their path rather than targeting their current position.
Use melee when close. If a runner is within 5 studs, do not throw the knife. Melee attacks are faster, guaranteed to connect if you are close enough, and do not have a cooldown the way throwing does. Many knife holders waste their throw on a close target, miss, and then have to wait for the cooldown while the runner escapes. Close the gap, melee, then immediately scan for the next target.
Wall-bouncing for trickshots. Advanced players use the environment to their advantage. Certain maps have walls and obstacles that can redirect your throwing angle. While wall-bouncing is difficult to master, it lets you hit runners hiding behind cover. Practice this in custom servers before trying it in public lobbies.
As a Runner
Never run in a straight line. This is the number one mistake runners make. A straight-line runner is the easiest target for any experienced knife holder. Use diagonal movement, sharp direction changes, and unpredictable patterns. Zigzagging at irregular intervals makes it nearly impossible for the knife holder to predict your position.
Use obstacles constantly. Every KAT map has structures, walls, and objects you can put between yourself and the knife holder. Break line of sight as often as possible. When the knife holder cannot see you, they cannot throw at you. Move from cover to cover rather than sprinting across open space.
Watch the knife holder's aim. Before the throw, the knife holder typically pauses and adjusts their camera. When you see them stop moving and turn toward you, immediately change direction. The throw has a slight wind-up animation that gives you a fraction of a second to react. Training yourself to recognize that animation and respond instantly is what separates top-tier runners from easy eliminations.
Stay at maximum range. The farther you are from the knife holder, the more the arc affects the throw and the more time you have to dodge. Position yourself at the opposite end of the map whenever possible. Only close the distance if the terrain forces you to or if you are trying to bait a throw before running behind cover.
General Game Sense
Learn the maps. KAT rotates through multiple arena layouts. Each map has different cover positions, open lanes, and chokepoints. Players who memorize map layouts consistently outperform those who react on instinct alone. Pay attention to spawn locations, popular hiding spots, and the fastest routes between cover points.
Sound cues matter. KAT uses audio cues for knife throws, melee attacks, and eliminations. Playing with sound on (and with decent headphones) gives you information that is invisible to players relying on visuals alone. You can hear a knife throw even when you are not looking at the knife holder, which gives you extra reaction time.
All KAT Game Passes & Robux Prices (2026)
KAT offers 8 game passes ranging from 25 Robux to 9,001 Robux. Each one provides a permanent benefit or cosmetic upgrade. Here is the full list with current pricing and what each pass delivers.
| Game Pass | Price (Robux) | What It Does |
|---|---|---|
| VIP | 95 | 2x coin earnings per round, VIP chat tag, access to VIP-only knife skins |
| MLG Pass | 350 | MLG-themed knife skin with unique sound effects and meme kill animations |
| MVP | 400 | MVP chat tag, exclusive knife skins, enhanced lobby effects |
| Shard Knives | 200 | Collection of crystalline shard knife skins with particle trail effects |
| Kill Effect Transfer | 120 | Lets you transfer kill effects between knife skins for full customization |
| Tesla | 600 | Electric-themed Tesla knife with lightning trail and shock kill effect |
| Spam Knife | 9,001 | Drastically reduced throw cooldown, allowing rapid-fire knife throws |
| Dead Meme | 25 | Meme-themed knife skin with retro sound effects on elimination |
Which Game Pass Should You Buy First?
If you only have Robux for one pass, buy VIP at 95 Robux. The 2x coin multiplier is the only pass that directly accelerates your progression. Every other pass is purely cosmetic or provides a situational gameplay change. With VIP, you will unlock knife skins through normal gameplay roughly twice as fast, saving you dozens of hours of grinding over time.
If you have a larger budget, the second best investment is the MVP pass at 400 Robux for the exclusive skins. The Spam Knife at 9,001 Robux is a luxury purchase that content creators like GamingWithKev have showcased, but it is not necessary to win. Skilled players without Spam Knife routinely outperform those who have it, because the reduced cooldown encourages sloppy aim habits.
Knife Skins, Kill Effects & Customization in 2026
Knife skins are the core cosmetic system in KAT. There are over 100 different knife skins available through the coin shop, game passes, and limited-time events. Each skin has a unique model, and many include custom trail effects and kill animations that trigger when you eliminate another player.
Skin Rarity Tiers
KAT organizes its knife skins into rarity tiers. Common skins cost between 100 and 500 coins. Uncommon skins range from 500 to 1,500 coins. Rare skins cost 1,500 to 3,500 coins. Epic and legendary skins start at 3,500 coins and go up to 10,000 or more. The rarer the skin, the more elaborate the visual effects, trail particles, and kill animation become.
Kill Effects
Kill effects are the visual explosion that plays when you eliminate another player. Standard kills show a basic poof animation. Higher-tier skins unlock effects like fire bursts, ice shatter, lightning strikes, pixel explosions, and rainbow particle clouds. The Kill Effect Transfer game pass (120 Robux) lets you mix and match kill effects across different knives, so you can pair your favorite knife model with your preferred elimination animation.
Music ID Customization
One of KAT's most popular features is the in-game radio system. You can enter Roblox Music ID codes to play custom background music during matches. This is purely cosmetic and does not affect gameplay, but it adds a personal touch to your KAT experience. Popular Music IDs change frequently as Roblox updates its audio library, so check community hubs like the KAT Discord server for current working IDs.
KAT Codes & Music IDs in 2026
KAT does not use traditional redeemable promo codes like many other Roblox games. There is no code redemption box where you type in a word to receive free coins or skins. Fierzaa has historically distributed rewards through in-game events and updates rather than code systems.
The only "codes" in KAT are Music ID numbers used for the in-game radio. These are standard Roblox audio asset IDs, not game-specific promo codes. You can find working Music IDs by searching the Roblox audio library directly or browsing community forums for popular song IDs that have been verified as functional in 2026.
How Coins Are Actually Earned
Since there are no codes to shortcut the grind, here is how coins flow in KAT. Winning a round as the knife holder awards the highest coin payout, typically 25 to 40 coins base (50 to 80 with VIP). Surviving a full round as a runner awards 10 to 20 coins base (20 to 40 with VIP). Getting eliminated early in a round still grants a small participation reward of 3 to 8 coins. Over an hour of active play, most players earn between 300 and 600 coins without VIP, or 600 to 1,200 coins with VIP active.

KAT vs. Similar Roblox PvP Games in 2026
KAT occupies a unique space in the Roblox PvP ecosystem. While several other games share elements of its design, none replicate the exact combination of physics-based knife throwing and last-player-standing rounds. Understanding where KAT fits helps you decide if it is the right game for your playstyle.
KAT vs. Murder Mystery 2
Murder Mystery 2 shares the "one player hunts others" format, but the gameplay loop is fundamentally different. In MM2, the murderer uses a knife in melee only, while an innocent player can pick up a gun to fight back. KAT removes the gun mechanic entirely and adds throwable knives, making it a purer test of movement and aim. MM2 also has a massive trading economy for knife skins, while KAT focuses on unlocking skins through gameplay rather than player-to-player trading.
KAT vs. Blade Ball
Blade Ball is another popular PvP game centered around a single projectile, but the core mechanic is deflection rather than throwing. In Blade Ball, a ball ricochets between players and you must time your deflections. In KAT, you are the one initiating the attack. Players who prefer offensive, aim-based gameplay gravitate toward KAT, while those who prefer reactive, timing-based gameplay tend to prefer Blade Ball.
KAT vs. Arsenal
Arsenal is a full FPS with weapon rotation mechanics similar to Gun Game from Call of Duty. It shares KAT's fast-paced PvP energy but plays very differently due to its first-person perspective and wide weapon variety. KAT's third-person camera and single-weapon focus create a completely different skill set. Many players enjoy both games and alternate between them for variety.
KAT's 2026 Return: What Changed After the Review
KAT went under Roblox review in August 2025, disappearing from the platform entirely for roughly 7 months. During that time, the community speculated about potential shutdowns, but Fierzaa confirmed development was continuing behind the scenes. On March 19, 2026, KAT returned to full public access.
The re-release maintained all previously existing features. Knife skins, game passes, coin balances, and player progress from before the review were preserved. Players who owned game passes like VIP (95 Robux) or Spam Knife (9,001 Robux) found their purchases intact upon returning. The player base recovered quickly, stabilizing at 10,000 to 20,000 concurrent players within the first few weeks.
While no major new features were added in the re-release itself, the game received performance optimizations and minor bug fixes during the review period. Loading times improved noticeably, and several animation glitches that existed pre-review were resolved. The community expects Fierzaa to roll out new content updates throughout the rest of 2026 now that the game is back on stable footing.
KAT Content Creators to Watch in 2026
If you want to improve at KAT faster, studying high-level gameplay from experienced creators is one of the best approaches. Several popular Roblox YouTubers have produced KAT content that demonstrates advanced techniques you can replicate in your own matches.
Tanqr is known for aggressive knife holder gameplay. His videos showcase prediction-based throwing at long range and rapid target switching between multiple runners. Watch how he positions himself in the center of the map rather than chasing a single target around the edges.
Sketch produces entertaining KAT challenge videos that also contain genuinely useful gameplay. His custom server videos with friends demonstrate advanced movement patterns for both knife holders and runners.
GamingWithKev has covered KAT's game passes extensively, including a dedicated video testing the Spam Knife pass (9,001 Robux) and comparing it against skilled players who do not have any passes. His content is useful for understanding whether specific passes are worth the Robux investment before you commit.

KAT (Knife Ability Test) FAQ 2026
Yes. KAT was re-released on March 19, 2026 after being under Roblox review since August 2025. The game is fully playable again at its original Place ID (4592931260) with all features, game passes, and player progress preserved from before the review period.
KAT does not use traditional redeemable promo codes. There is no code redemption interface in the game. The only "codes" players use in KAT are Roblox Music IDs entered into the in-game radio for custom background music. Be wary of any website claiming to offer KAT promo codes, as these are scams.
The VIP game pass at 95 Robux offers the best value. It provides a 2x coin multiplier that permanently doubles your earnings, letting you unlock knife skins roughly twice as fast. For 95 Robux, it pays for itself quickly in terms of time saved grinding for coins.
When selected as the knife holder, you can throw your knife at other players. The knife follows an arc trajectory, meaning it drops over distance like a real thrown object. For close targets (under 20 studs), aim directly at them. For distant targets (30+ studs), aim slightly above to compensate for the arc drop. After throwing, there is a cooldown before you can throw again (unless you own the Spam Knife pass).
KAT maintains approximately 10,000 to 20,000 concurrent players at any given time and has accumulated over 2.2 billion total visits. These numbers have remained stable since the game's re-release on March 19, 2026, making KAT one of the most popular PvP games on Roblox.
KAT (Knife Ability Test) was created by Fierzaa. The game has been one of the most successful PvP experiences on Roblox, generating over 2.2 billion visits since launch. Fierzaa continues to maintain and update the game following its 2026 return.
The Spam Knife game pass costs 9,001 Robux (a reference to the "over 9,000" meme) and drastically reduces the cooldown between knife throws, letting you fire knives in rapid succession. While it is powerful, skilled players without the pass regularly outperform Spam Knife users because the rapid throwing encourages careless aim. It is primarily a content creator and flex purchase rather than a competitive necessity.
Yes. KAT is fully playable on mobile phones, tablets, PC, and Xbox. However, PC players have a significant advantage due to mouse-based aiming, which is more precise for knife throwing. Mobile players can still compete effectively by focusing on movement and positioning as runners, and by practicing touch-based aim in custom servers when playing as the knife holder.
KAT continues to be one of the most rewarding PvP experiences on Roblox heading through 2026. Whether you are a returning veteran whose progress survived the review period or a brand new player discovering the game for the first time, the combination of skill-based knife throwing, extensive cosmetic progression, and fast-paced rounds creates a gameplay loop that keeps pulling you back. Focus on mastering the throwing arc, invest in VIP if you can spare 95 Robux, and put in the practice time on custom servers. The skill ceiling in KAT is high enough that there is always room to improve, and that is exactly what makes it worth playing.
