We Ponder a Murder Mystery With Nikilis


Trust no one.

If you’ve logged into ROBLOX anytime in the past couple days, you’ve noticed Murder Mystery. It’s been sitting at the top of the Popular games list, at times hitting roughly 5,000 concurrent players. Based on a popular Garry’s Mod game, the premise is simple: you spawn in a world populated by civilians, a single sheriff, and a killer. What’s the catch? You don’t know who the killer is. It could be anyone.

We got the chance to have a chat with the developer, Nikilis, about this breakaway ROBLOX hit that quickly became the biggest game on ROBLOX — before he was finished making it.

Here’s how the game works: if you’re the killer, it’s your job to stealthily take out every player in the map while avoiding detection. If you’re the sheriff, it’s your job to find and eliminate the killer. Making things more interesting, every person in the game looks approximately the same and leaves colored footprints, which can be used as clues. There’s a social aspect that’s refreshing — chatting is of paramount importance, as players are constantly predicting who the killer is, and sometimes more importantly, where he is on the map.

Murder Mystery isn’t Nikilis’ first brush with fame — his Trucking Tycoon is a popular title that has been played over a million times. But both the exposure and sheer number of place visits Murder Mystery has received (about 150,000 visits in two days) was certainly unexpected, particularly because the game is only partially completed.

I massacred everyone when I finally got a chance to play as the murderer.

I massacred everyone when I finally got a chance to play as the murderer.

“I have a lot of people in fan groups, but I didn’t expect this to happen. I was testing the gameplay mechanics with a few friends, but they actually weren’t that interested,” he recalls. “So I sat in a server by myself, and posted the link on some my group walls. I finally got one server full and decided to go to bed. When I woke up, there were thousands of people playing the game.”

As mentioned earlier, Nikilis found inspiration for Murder Mystery while playing a Garry’s Mod game, which acts as the baseplate for the mechanics. That baseplate is currently the core of the game, but there are still loads of features and changes on the way. The game’s surge in popularity is unlikely to diminish soon.

Even as just a baseplate, Murder Mystery is an extremely enjoyable experience. It’s coded in a way that makes the game feel almost unnaturally smooth, and the way gameplay collides with psychological elements makes it unlike most ROBLOX experiences.

“I’m glad it got so popular after I had at least finished the core gameplay mechanics,” says Nikilis. “It’s got all the basic gameplay elements I needed. Now I have to try and make the game more unique and stray from the game that inspired me a bit.”

He goes on to list a bevy of features he’s planning on implementing: an official shop where you can buy perks and change the way your knife looks as the murderer. More game modes, including a mode where everyone is a murderer (thus making a literal representation of the word deathmatch), as well as a mode that includes more than one murderer. He’s also planning on giving users the ability to alter their appearance and faces. Oh, and he’ll be adding more maps to supplement the three existing ones. I told him that one of the truly great parts of Murder Mystery is how the chat system is used as a core mechanic.


Examine scenes of murder carefully. Here, we can deduce that the murderer is wearing either a blue, yellow, or pink shirt.

“I planned on chat being a core feature, because everyone is given a random name. People keep telling me to change the chat system or remove it, but I think it’s best the way it is. Dead players can’t talk, which forces the murderers to work quickly. The people who are murdered can’t give anything away.”

When asked about the actual development of the title, Nikilis made a shoutout to user GigsD4X, who created a ROBLOX tool set that was vital in developing the title. It’s basically an all-in-one tool that combines many core elements of building, like resizing, moving, and changing object color.

“I’m not so great at building,” says Nikilis. “But these tools made it so much easier.”


Already a DevEx veteran, Nikilis has converted over a million ROBUX into real-life cash, which he’s saving for future endeavors. He’s also working to determine what sort of Game Passes he can implement that maintain the game’s balance — a difficult task to accomplish, as he doesn’t want to alter the core gameplay mechanics.

In closing, I asked him what makes the ROBLOX version of Murder Mystery even better than the original. This was his response:

“My favorite fundamental change is that everyone can see everyone’s footsteps, rather than just the murderer. This means the murderer has to be even more careful. There’s a lot to come — the game sort of exploded when I wasn’t finished yet, so I’ll be adding more features really soon.”

We look forward to it.

    Wow, this game is amazing. I love the way it is built, and the scripting is awesome. But, the owner misunderstood what we meant by “Remove the Chat.” People who are alive yell out the killer’s name and it gets hard for the killer. TOO hard. Otherwise, great game!

      I play this game often but never once was i the murderer or th ecop so i wonder if you need the weapon first

      1. Anonymous

        It’s based on the percent chance in the lower right corner. The higher the number, the better the chance. If you are at something like 21%, you will be something in the next game or two.

  2. noobie84

    Garry’s mod is a good game and theres been like acouple of ROBLOX versions of the Gmod gamemodes. But this one has to be my favorite. Hope there will be a TTT

  3. ninjasaga2222

    The part that I hate is that why is my chances of being the killer or sheriff is taking too long.Because i’m always the victim, I always need to avoid the killer.>:(

  4. Serria

    This game is amazing! Simple but yet so enjoyable and addictive! I can’t wait to see the other features he adds into the game!

  5. smoshruler28

    I have played this and I believe that this is the most popular, most well directed, most amazing game I have ever played by this amazing ROBLOXian, Nikilis.

  6. TheFatTree

    Well, i truly think he did really good on this. Can’t wait until the level with everyone a killer :D

    1. Epicfacedarkmaster

      Notice: It says several times in the article that he got his inspiration from that game.

    2. NikeEclipse

      Dis game isnt related to TTT its GMOD name is Murder. In TTT there is a traitor not a murderer. Both games work the same way apparentlly.

  7. theirnamewastreason

    Honestly, I have to say I think the game is well made, a bit like a few other games on ROBLOX, but still very good.

  8. welll

    wish there were more games than murder mystery the only game I can play with people on it Its a great game I love it alot

  9. phantomoftheopera456

    I played this game a couple times. Its a thrilling game, but some people find it annoying that you BARELY get to be the Sheriff or the Murderer.

  10. Supsick

    The creator is asking EVERYONE in the fan group what he can add to make being an innocent more entertaining or interesting.

  11. ArchangelTheory

    “If you’ve logged in anytime in the past couple of days, you’ve noticed Murder Mystery.”

    Nope. I log in often, but I almost never play games. I am always busy with my clan.

  12. superemmy868

    I’ve played this game a lot already…maybe a little too much. XD I love it though. I love how the murderer is picked by the percentage of games you’ve played as someone other than a murderer. That way everyone gets a chance to be it. I hope he gets in a ton of maps though.

    1. zoy2

      Well, he added % so you have to win to be murder. Each % is much luck you have of being murder (editors right, never write murder so much)so not everyone has a chance.

      1. ninjasaga2222

        I NEVER got the chance to be sheriff and I got to be killer SOMETIMES. does roblox always wants me to be the victim.

  13. SparkeRebel6

    I absolutely luv this game!I was thinking about the maps and maybe if you can make one of the following choices!
    1) The cinema
    2) Abandoned factory
    3) A map based on the game Slender!

    THX!!! :D

  14. trollmaster303

    So, this game gets an interview and it’s only been around for a week, when Trouble in ROBLOX Town came first, and no one ever thinks about it?

  15. Klone36
