Want a Secret skin in Murder Duels? Opening cases is the main way to get new knife and gun skins. There are 4 cases in total, but only 2 of them give skins and are still in the shop.
This page lists every skin inside each case, what each case costs in coins and in Robux, and how much the bundles really save you. All prices were checked on September 23, 2026.
Quick answer. If you spend Robux, buy the case itself, not coins. A Recruit Case costs 9 Robux on its own. In the shop it costs 1,200 coins, and 1,200 coins is exactly the 80 Robux coin pack. That is almost 9 times more for the same case.

The game does not show drop odds for any case. You can see which skins are inside and how rare each one is, but not your chance of getting it. So you will not find a percent for any skin on this page.
Recruit Case: all 16 skins
The Recruit Case is the cheapest case and the one you will open the most. It holds 16 skins. The 2 Secret ones are the Saber knife and the Ray Blaster gun.

Founder’s Case: 16 skins you can only trade for
The Founder’s Case was in the game from launch and cost 4,000 coins. It left the shop on July 5, 2026, in the same update that added trading. So since the day these skins stopped dropping, trading has been the only way to get one.
5 of its designs come as a gun and knife pair: Heartbreaker, Inferno, Kitty Cone, Lightning and Seraphim. Toxic and Constellation don’t have a gun or knife type listed yet.

The Finishers Case
Finishers are the effects that play when you knock someone out. Since June 26, 2026, you get them from the Finishers Case instead of by rerolling. It costs 2,500 coins and has no Robux price, so coins are the only way to buy it. The full list of what it holds has not been posted yet.
Why buying coins first costs you more
Here are the coin packs the game sells right now. The more Robux you spend, the more coins you get for each one.
| Coin pack |
Robux price |
Coins per Robux |
| 1,200 coins |
80 Robux |

| 5,250 coins |

| 75,000 coins |
4,000 Robux |
18.8 |
| 200,000 coins |
10,000 Robux |
20 |
Even at the best rate, 4,000 coins for a Space Case works out to 200 Robux. Buying the case straight away costs 120. For a Recruit Case the gap is even bigger: 9 Robux direct, or 80 Robux of coins.
Old coin prices are wrong. The coin packs changed on July 26, 2026. Lists that still show 500 coins for 49 Robux are from before that update.

Four bundles also sell every item on its own, so you can check the math. Each one costs less than its parts. The Energy Bundle saves the most, 700 Robux. It also lets you pick a red, green or blue version.
The Starter Pack is the cheapest bundle at 99 Robux. It gives you the Molotov Knife skill, 3 Recruit Cases and 1,000 coins. Those 3 cases alone would cost 27 Robux if you bought them one at a time.
Collectibles and code skins
Collectibles are limited skins that sell out. None of the 4 below were on sale on September 23, 2026, so trading is the only way to get one now.

- Chroma Katana (knife): came in Update 8.5 (August)
- Murder Note (gun): came in Update 9 (August 16), was 5,000 Robux
