Last Updated: August 2026 | Controls, shop and codes checked against the live game.
Knife Arena is a first person free for all where everybody has a knife and nothing else. Twelve players share one room, there are no teams, and you respawn almost immediately after dying. A light attack is quick, and a heavy attack kills in one hit but leaves you open.
It opened in December 2025 and has passed 131 million visits in about eight months, which is very fast. This page covers the controls, what credits and crates are for, the two free boosts the game hands out, and how little there is to buy.

How to Play Knife Arena
There is almost nothing to learn, which is the point. The depth is all in the timing.
- Redeem the five codes before you start. They pay in cases, and three of them are limited.
- Join a match. Twelve players, no teams, and everyone has the same knife you do.
- Use the quick attack most of the time. It is safer and it is what most fights come down to.
- Save the heavy attack for someone already swinging. It kills outright but it is slow.
- Bring a friend along. The game gives 20 percent more credits for playing with friends, free.
- Spend credits on crates. That is where the knife skins come from.
How a Round Works
Six things describe this whole game, and the last two are the ones people find surprising.
| Part |
What it is |
How it works |
| The fight |
Everyone for themselves |
Twelve players, no teams, one knife each and very fast respawns. |
| Two attacks |
Light and heavy |
A quick swing or a slow one that kills outright. Choosing between them is the game. |
| Credits |
Earned in matches |
The only currency, and it is what opens crates. |
| Crates |
Where the skins are |
Codes pay in these. So does playing. |
| The shop |
One item |
A single VIP pass at 399 Robux. There is nothing else for sale. |
| Badges |
None at all |
This game has no badges, so there is nothing to collect on your profile. |
The last row is the one most people miss. Joining the group is free, takes one click and permanently raises what you earn, and the game states it on its own page.
Knife Arena Gameplay: People Keep This One
This game has no badges at all, which is rare for something this size and means there is no progress list to read. There is one number worth looking at instead. Roblox counts how many people favourite a game, and this one has over a million against 131 million visits.
| Game |
Favourites per visit |
For comparison |
| Knife Arena |
1 in every 121 |
This game. One visit in 121 ends with somebody favouriting it. |
| A shooter |
1 in every 27 |
The highest we have measured on a game that does not ask for it. |
| A gun builder |
1 in every 271 |
A very well liked game, and still well behind this one. |
| A street game |
1 in every 387 |
Another big open world game with a strong rating. |
| A sandbox |
1 in every 1,963 |
The other end of the scale, for comparison. |
That works out at roughly one favourite for every 121 visits, which puts it high up among everything we have measured. For a game that is only eight months old, that is a lot of people deciding to keep it.
There is one more thing that makes it count for more. Some games ask players directly to like and favourite them, right there in the description, which naturally pushes the number up. This one does not ask at all.
So the figure is unprompted, and that is worth more than a bigger number somebody was nudged into. It fits the 88 percent like rate sitting next to it.
What The Shop Actually Sells
The developer publishes the full control list on the game’s own page, and it is short enough to be worth repeating here.
| Action |
Button |
What it does |
| Light attack |
Left mouse / R2 |
Quick and short reach. This is your normal swing. |
| Heavy attack |
Right mouse / L2 |
Kills in one hit, but it is slow, so it has to be timed. |
| Crouch and slide |
Ctrl or C |
Movement rather than combat, and the main way to close distance. |
| Inspect |
V or Y |
Shows off your knife. It does nothing to help you win. |
| Mobile |
Auto aim |
Phones and tablets get auto-lock and auto-attack built in. |
| Consoles |
Supported |
Xbox and PlayStation 5 both work, with the controller layout above. |
The heavy attack is the whole game in one button. It kills in a single hit, which sounds unbeatable until you use it and find out how slow it is. Most fights are won by throwing quick swings and saving the heavy one for somebody who has already committed.
The other thing worth knowing is free. The game says on its own page that playing with friends earns you 20 percent more credits per match. It also says players who pay Roblox a monthly fee get 20 percent.
Those are the same number. Bringing one friend along gets you exactly what the paid route does, and that is the only boost in the game worth chasing. The shop itself holds a single VIP pass at 399 Robux and nothing else at all.
Codes
There are five working ones and every single one pays a case rather than credits. Three of those cases are limited, so they are the ones to type first. Our Knife Arena Codes page lists them all and shows where the redeem box hides.
Who Makes Knife Arena
It comes from One Hit Studio, a verified group with more than three million members. Knife Arena opened in December 2025 and was updated today.
It has passed 131 million visits and been favourited over a million times in about eight months. About 88 in every 100 votes on it are likes, and it runs on computer, phone, tablet, Xbox and PlayStation 5.
Tips for New Knife Arena Players
- Redeem the five codes first. They pay in cases, and three of those cases are limited ones that will not come back.
- Bring a friend into your match. The game says playing with friends earns 20 percent more credits, and it costs nothing.
- That free boost matches the paid one exactly, so there is no advantage in paying for it.
- Save the heavy attack for someone who has already committed to a swing. It kills in one hit but it is slow enough to punish.
- Use crouch and slide to close distance rather than running straight in. Most deaths happen in the open.
- On a phone the game does the aiming for you, so play the movement rather than the aim.
- Do not run scripts here. The game says cheating means a permanent ban with no second chances, in those words.
- Nothing in the shop or the codes makes your knife stronger, so there is no purchase that will win you a fight.
