	―- Game Description

Info

Players survive one of the 36 killers that spawn on the Red Circle of Oculus in 90-second rounds between 45-second intermissions. When a round starts, the map turns dark and when all surviving players die, the round immediately ends. For each survival, 20 points are given (95 for a badge killer), which are used to buy coils and power-ups in the shop. Points do not save when the player leaves. Every five rounds, a vote for the next map will begin.

Killer List

A list of every killer that can appear in-game. (KILLERS ARE SORTED BY CREATION DATES (Excluding Spacknick, which replaced Crazy Robloxian))

[ KILLERS ]
Image	Name	Type	Difficulty	Strategy	In-Game Description
	Spacknick	Regular	8/10 (Extreme)	They are weak on some maps due to the invisible barriers. Use them to your advantage. Do not run in straight lines. Snow Boots is extremely useful for this killer. Being high above ground isn't efficient, as they can jump.	They will do absolutely anything to reach you. Behind a wall? No worries, they can go around! Have the high ground? They can jump! They're here to cause terrors overnight of course!
	Slungus	Regular	2/10 (Easy)	Use a coil fast enough to outrun them.	aaaaahh scary
	SCP-409	Regular	3/10 (Easy)	Use a coil fast enough to outrun them.	Also known as the Contagious Crystal, i believe. It's a large crystal that would've crystallized anything that came into contact with it.
	Apocalypse	Regular	4/10	Use a coil fast enough to outrun the Gold Zombies.	Multi-Killer. Make sure you have good mobility items
NO IMAGE AVAILABLE	Deluxe Detroit	Regular	4/10	Use a coil fast enough to outrun them.	Deluxe Detroit, one of the members of the Lawful Cartel.
	A-60	Regular	4/10	A fast killer. Use at least Ultra-Heliotrope Coil.	This one reminds me of a certain office.
NO IMAGE AVAILABLE(?)	_ERROR	Regular	3/10	Just stay away from them. They have a huge hitbox but they are slow.	Originates from PARTY.exe.
	Subject_0	Regular	4/10	Just stay away from them. They are faster than _ERROR however, so use a good coil.	Originates from PARTY.exe.
NO IMAGE AVAILABLE	bear5	Regular	3/10	Due to this killer's recent rework, the difficulty may be inaccurate. Keep a distance away from bear5 and BlueChica's Bombs.	har
NO IMAGE AVAILABLE	Tactical Hamburger	Regular	3/10	Huge Hitbox, just stay away from them.	This killer looks like dinner, but your not finishing it, instead it finishes you off,, with its dual miniguns.
	Evil Otto	Regular	3/10	Stay away from Evil Otto and their robots.	DESTROY HUMANOID! This is a Multi-Killer which consists of 4 robots and Evil Otto.
	Ao Oni	Regular	2.5/10	Just stay away from them.	If you have a coil, there's no need to worry about this one.
	Fuwatti	Regular	3.5/10	Slightly faster than Ao Oni. Randomly does dashes, which momentarily speed up Fuwatti.	This one is a bit faster than Ao Oni.
	Specimen 2	Regular	4.5/10	As of January 4th, 2026, this killer's Teleport ability is broken, and will be fixed in the next update. (Upd. 22) Just avoid them.	Mobility isn't saving you, so just hope that it doesn't teleport to you.
NO IMAGE AVAILABLE	Killer Fish	Regular	3/10	Just avoid them.	The Killer fish from (?)
	SCP-087-B	Regular	4.5/10	They are a bit quick, one can teleport behind random players. Use a good coil.	The Endless Staircase.
	Luigi Doll	Regular	4/10	Similarly to Fuwatti, Luigi Doll can charge quickly at players. Just avoid them.	Lugi doll
	CENSORED	Regular	3/10	Just avoid them.	Well, i'm not sure what this one is meant to be, but it's a killer, so like... avoid it?
	Evil Thwomp	Regular	evil thwomp	Just avoid them.	Evil Thwomp
	Cave Dweller	Regular	4.5/10	Just avoid them.	A bit fast, and makes interesting noises, But what do you do with a coil? You run with it, and away from this thing.
	KACTUSMAN	Regular	6/10	Use a good coil and stay far from them.	Oh this killer plays sounds whenever it attacks players, thats hilarious.
	Barbershop Haircut	Regular	6.5/10	You can use any mobility item at the start of the round, but he speeds up for each kill, so preferably use a good coil.	He looks like he would charge a quarter for his haircuts.
NO IMAGE AVAILABLE	Integrity	Regular	8.5/10	At the beginning of the round, it will slowly move towards the closest player. Once the timer reaches 30-45 seconds, it will begin to move at crazy speeds.	YOU WILL BECOME ONE OF US.
	Speeding Wall	Regular	9/10	This killer is incredibly difficult to go around, especially in small maps/maps with many barriers. Speeding wall spawns behind the players torso direction, meaning its spawn position can be manipulated. Multiple walls can spawn simultaneously, making it incredibly difficult.	Don't get crushed by the speeding wall! Oh, and if you face this killer in challenge cube, good luck on that.
	Viejito_chulo	Regular	4-6.5/10	(HEADS UP: THIS KILLER IS EXPECTED TO RECEIVE A REWORK IN UPDATE 22!) (THIS KILLER'S BADGE IS ONLY OBTAINABLE ON A SPECIFIC MAP!) Just avoid them with a good coil. They are somewhat slow, but on their map their only buff is increased speed.	Be aware of his super secret base...
NO IMAGE AVAILABLE	Roaring Knight	Regular	7.5/10	Roaring Knight has 3 attacks. Avoid the white slashes. Don't touch the stars, and do not stay in the red circle's radius for too long or you will be SWOONED..	Swoon
NO IMAGE AVAILABLE	Pursuer	Regular	4.5/10	Pursuer can be outran with possibly Ultra Coil. Pursuer can go invisible and reappear near players.	He will make you die (of death)
NO IMAGE AVAILABLE	The Glitch	Regular	3/10	Makes the round more foggier/darker, kind of slow, so it can be easily outran.	so GLITCHY. this killer needs fixing.
	Voxel Terrain	Regular	6/10	Floats around players, Voxel terrain can crush players, so listen for the audio cue and get away when you do. Can summon Voxel Monsters, and shoot neon green.. voxels?	"add voxel terrain to overnight terros" "Ok"
NO IMAGE AVAILABLE	Stamper	Regular	5/10	Jumpscares (and instakills) players on contact. Slightly faster than the normal walkspeed, so use any coil.	Hello
	Badware	Regular	6.5/10	Can bolt towards players and place computers. Bolt's damage intially starts at 5-10, but increases by 10 for every created computer.	CAN I HAZ ONE SURVIVALZ?
NO IMAGE AVAILABLE	Artful	Regular	6.5/10	Be cautious as Artful can appear behind a random player. Artful can summon fake clones which are faster but deal less damage.	This guy's performance stinks.
NO IMAGE AVAILABLE	Nullscape Entities	Regular	9.5/10	The "Baby" Entity winds up before dashing at the player in a straight line, move out of its way. The "Voidbound Baby" Entity is a Baby variant, which is much faster than Baby. The "Flesh" and "Mart" Entities are slow, so they cannot do much. The "ICBM' Entity locks on to the nearest player, before it falls onto the players last location, exploding. The "Telefragger" Entity will spawn in front of a random player, don't touch it. Its position can be manipulated.	COLLECT MY GIFTS! FIND MY FLAMES!
	LOL	Regular	6.5/10	Orange (LOLHOO) chases the nearest player and chomps away at them. Pineapple (LOLWUT) slowly chases, but can randomly begin a spin attack, moving at incredible speeds, flinging players. LOLBERRY is the same as LOLWUT, but has a much slower spin. Apple (LOLHOW) will stab repeatedly at players if they're close enough until they're dead.	LOLHOO IS THIS KILLER?
	Flowers	???	?/10	Flowers is a killer expected to release by Update 22. Check back soon ??? ??? ???	???
	THIRD	???	?/10	THIRD is a killer expected to release by Update 22. Check back soon ??? ??? ???	???
	Krazy Bus	???	?/10	Krazy Bus is a killer expected to release by Update 22. Check back soon ??? ??? ???	???
	Joy	Badge	7/10 (Hard)	Most coils except for Emerald Coil cannot outrun Joy. It is highly recommended to use Snow Boots against Joy.	Once awakened, Joy can be a huge problem. No fast coils in your inventory? You might aswell call it GG.
NO IMAGE AVAILABLE	The Button	Badge	5/10	Only survivable if everyone in the server decides not to trigger the button. There is a slight chance that when pushed, will grant everyone a lot of points, minus the badge of course.	All it takes is one push of a button, and everyone will be nuked, i advise you to.. NOT push it.
	Ultra Irios	Badge	6.5/10	Due to this killer's Recent Rework, the Difficulty may be inaccurate. Goes for the nearest player at insane speeds, shoots a volley of fireballs. This killer can only be outran with Emerald Coil or Snowy Coil and better + Snow Boots.	You will definitely want to avoid this one. He shoots fireballs.
	Glerk	Badge	7.5/10	Use a good coil for this killer, If your the target, its direction can be manipulated by your character.	This one acts similarly to Joy. It has an anger meter, so let it kill you, unless you want it to kill everyone else.
