Last Updated: August 2026 | Monster list, badge counts and pass prices checked against the live game.
SCP Monsters or Trevor Creatures drops you into a building full of things that want to catch you. SCP 096, SCP 173 and Siren Head are all in there. You can run from them with fourteen other players, or you can pay to swap into a monster body and watch from the other side. It opened in February 2022 and has passed 438 million visits.
There is no fan wiki for this game, so everything here comes straight from the game itself. This page covers which monsters are in it and where each one comes from, how many players ever meet them, and what all six passes really do before you spend anything.

How to Play SCP Monsters or Trevor Creatures
There is no tutorial and no goal written down anywhere. The whole game description is four lines long. Here is what actually works.
- Join a server with people in it. Fifteen fit in each one, and an empty building is far less fun than a full one.
- Walk the building and find the monsters. Meeting one is what earns you a badge, so exploring is the point.
- Learn what SCP 096 does first. Nearly seven in ten players meet it, so it will probably be your first.
- Keep looking for SCP 173. Only about a quarter of players ever find it, which makes it the real target here.
- Buy a room pass only if you want to be the monster. Every pass unlocks a room with morphs or guns inside.
- Read what a morph pass says before buying. Both morph passes say plainly that they cannot kill anyone.
There is no way to lose the game permanently. Getting caught just puts you back in, which is why people keep going in for four years.
SCP Monsters or Trevor Creatures Gameplay
This game has no coins, no XP and no levels. That is rare for something with 438 million visits, and it changes everything about how you play. Nothing you do is saved as a score, so there is no grind and nothing to catch up on.
What you get instead is badges. There are only four, and three of them are for meeting a specific monster. Once you have all three there is no further ladder, so the game turns into somewhere you go to mess about with friends.
The two halves of the game are running and chasing. Free players do the running. Players with a morph pass can swap into a monster body, though the game does not let those morphs actually catch anybody.
Everything you can buy is a room. The passes unlock doors inside the building rather than giving you an item to carry, which is why the map has locked areas in it.
Every Monster and Where It Comes From
The game’s name has two halves and each one points at a different source. That is not decoration, it is exactly what is in the building.
| Monster |
Comes from |
What to know |
| SCP 096 |
SCP Foundation stories |
The one almost everybody runs into. It has its own badge and its own morph. |
| SCP 173 |
SCP Foundation stories |
The rarest meeting in the game. Only about a quarter of players ever get this badge. |
| Siren Head |
Trevor Henderson’s creatures |
The Trevor half of the game’s name. About 38 out of 100 players meet it. |
| SCP 682 |
SCP Foundation stories |
No badge for this one, but you can turn into it with the morph pass. |
| SCP Boss Monsters |
SCP Foundation stories |
Four of them, listed as Boss 1, 2, 4 and 5 on the pass that unlocks them. |
The SCP half comes from the SCP Foundation, a collection of horror stories written by a lot of different people online. SCP 096, 173 and 682 are three of the best known.
The Trevor half is different. Siren Head was created by an artist called Trevor Henderson, and it belongs to him rather than to a shared story site. That is why the game says it is inspired by both.
One small oddity worth flagging. The boss pass lists its monsters as Boss 1, Boss 2, Boss 4 and Boss 5. There is no Boss 3 in the list, and the game never explains where it went.
How Many Players Meet Each Monster
Every meeting gives a badge, and Roblox counts how many players hold each one. With only four badges in the game, that adds up to a complete picture of what people do in there.

SCP 173 is the one to aim for. Three quarters of the people who have ever loaded this game have never met it, which makes it the hardest thing here by a wide margin.
Now the number that says the most about this game. Nearly 99,000 players joined it for the first time yesterday, and it has not had an update since October 2024.
Work out yesterday’s shares and they come to about 69, 37 and 24 out of every 100. The all time shares are 69, 38 and 25. They line up almost perfectly, which means the game is being played today exactly as it has been for four years.
All Six Gamepasses and What They Cost
Six passes, and prices come straight from Roblox this week. None of them is needed to play.
| Gamepass |
Price |
What it does |
| Golden Gun Pack |
25 Robux |
Opens the Golden Gun room. The cheapest thing in the game. |
| Big Head Morph |
40 Robux |
Opens the Big Head room, and you can change some of the colours. |
| Diamond Gun Pack |
60 Robux |
Opens the Diamond Gun room. Its own page says it beats the Golden Gun. |
| SCP Morph Room |
80 Robux |
Turn into SCP 682, SCP 096 and more. These morphs cannot kill. |
| Become SCP Boss Monsters |
180 Robux |
Turn into four boss monsters. They cannot kill and you get a small body. |
| Crystal Gun Pack |
380 Robux |
Opens the Crystal Gun room. Its own page says it beats the Diamond Gun. |
The three gun packs are a ladder, and the game says so itself. The Diamond pack states it beats the Golden one, and the Crystal pack states it beats the Diamond one. So the 380 Robux pack is the top of the pile.
The morph passes need a warning, and it comes from their own descriptions rather than from us. Both say the morphs cannot kill. The boss pass adds that you get a small body. So the 180 Robux pass, the second dearest in the game, actually makes you less dangerous, not more.
All six passes were made in 2022 and none has been changed since October that year. Whatever you pay today is what players have paid for four years.
Who Makes SCP Monsters or Trevor Creatures
This game is made by lolbuih, one person rather than a group. They have nine games on Roblox that have picked up around 1.34 billion visits between them, and the list is a strange mix of SCP horror, ships, trains and planes.
They also made a second SCP game with a very similar name, SCP Games and SCP Monsters, which came out about six months earlier and calls itself the original. It has more visits overall. This one has roughly twice as many people playing right now, which catches most people by surprise.
About 69 out of every 100 votes on the game page are likes. That is lower than most games this size, and it fits something built around getting caught.
Tips for New SCP Monsters or Trevor Creatures Players
- Join a busy server. Fifteen people makes the chase far better than wandering an empty building on your own.
- Go looking for SCP 173 on purpose. Three quarters of players never meet it, so it is the closest thing here to a real challenge.
- Read a morph pass before you buy it. Both of them say in their own description that they cannot kill anyone.
- Start with the cheap passes if you are curious. The Golden Gun is 25 Robux and the Big Head Morph is 40.
- Do not expect the boss morph to make you strong. It is the second most expensive pass and it gives you a small body that cannot kill.
- Remember every pass is a room. Buying one unlocks a door, so the thing you paid for is somewhere to go, not something you carry.
- Do not go hunting for codes or scripts. This game has neither, and the results you find belong to other games with nearly the same name.
