Killer or Not officially says it has other game modes, and Roblox’s Universe Places API names one additional Place: Killer Or Not (Assassin). Those facts support a mode hub, but they do not support a fabricated complete list. Assassin is the only public mode-like name tied directly to the official Universe at the 2026-08-07 UTC checkpoint.
This page is a currently documented mode index. It shows what is official, what a player should read in the current round, and which fields must be observed before a mode-specific strategy can be published.
Evidence status: multiple modes and the Assassin Place name are Official. Assassin’s entrance, player distribution, targets, objectives, timer, abilities, weapons, rewards, and win conditions need in-game testing.
Mode index at a glance
- Root Killer or Not experience: Place
127994242634536. The official description establishes a killer, players running away, teammate help, and other modes, but does not name the root round type. - Killer Or Not (Assassin): Place
109194139422297in the same Universe8901905971. The Place relationship and name are official. The public Place description is empty. - Other named modes: none verified in the current public first-party data. Names from videos, clips, or search tags are not added unless the correct experience and current UI clearly establish them.
Calling this list “currently documented” matters. Roblox Universes can contain internal or alternate Places that players reach through the root experience. A Place name proves identity, not the menu route or present availability for every server.
How to identify the mode you actually joined
Begin at the official root experience. When a round starts, record any mode name shown in the lobby, assignment screen, objective panel, or result. Use the exact capitalization and wording. Do not derive a mode name from a single weapon, character appearance, or chase moment.
Next, read the assignment and objective. A mode is defined by what the round asks players to do and how it decides the result, not just by the presence of a killer. Note the target, progress indicator, timer if visible, interactions, and end message.
Finally, distinguish the root Place from the Assassin Place. Roblox may move players between Places inside a Universe without presenting the full destination as a normal web link. If the client or server information exposes Place 109194139422297, that is strong evidence you are in Assassin. A title in a video description is weaker.
Assassin: what is confirmed
The official Universe Places endpoint lists Killer Or Not (Assassin) with Place ID 109194139422297. It belongs to the same Universe as the root game. That is enough to establish the name and relationship, and to help players distinguish it from an unrelated Roblox experience.
The public Place entry provides no written rule description. We therefore do not state how to enter Assassin, how many sides it has, who receives a target, whether roles are hidden, which actions are allowed, how long a round lasts, or what counts as a win. “Assassin” can suggest familiar mechanics, but genre familiarity is not evidence for this implementation.
If you reach this Place in game, capture the route from the root lobby, the mode introduction, assignment text, objective, prompts, and result. A single full current round showing those fields could support a cautious Assassin guide; two independent current observations would be stronger.
Read round rules in the right order
Use this sequence for any mode:
- Name: exact title shown by the game.
- Sides or assignments: the labels each player receives.
- Objective: the action the game says advances the round.
- Eligibility: who or what can be targeted or helped.
- Controls: only prompts visible for the tested device.
- Progress: counters, markers, timers, or state changes.
- End condition: the message or event that closes play.
- Reward: exact visible name and amount, if any.
Do not fill a missing field with a convention from another title. For example, 1-vs-All does not automatically prove a generator, voting, rescue, stamina, gun, melee, elimination, or last-player system.
Decide what to do in an unfamiliar round
Pause long enough to read the first instruction. Identify whether the screen names a threat, target, teammate action, destination, or survival condition. Follow one labeled prompt and observe whether the progress display changes. That direct feedback is more useful than guessing the entire ruleset.
If the round provides no clear instruction, follow visible game markers and avoid irreversible actions until the objective becomes readable. After the round, use the result screen to correct your interpretation. If the same instruction fails to appear on a second server, record it as a possible UI issue and use Troubleshooting.
For team play, communicate the exact mode and objective words shown by the game. A short message tied to current UI avoids spreading a wrong rule across the server.
Mode claims this index rejects for now
Search history for the same Place has included broad tags such as killer, traitor, assassin, roleplay, and mystery. Tags help discovery, but they do not prove five separate modes. This index does not turn each tag into a route.
Community clips show active gameplay and player techniques, but short titles such as “air shot” or “camper” lack enough context to establish a weapon, map, role, or mode rule. Similarly, the official description’s phrase “other game modes” does not reveal their names.
Maps, weapons, items, currency, shops, and mode rewards also remain outside the index until current evidence supports stable entities. Publishing an empty matrix of guessed names would be less useful than one trustworthy Assassin record.
When a dedicated mode page becomes publishable
A mode deserves its own page when current evidence answers the practical route and operation questions: how a player enters it, what assignment appears, where the round starts, what action advances the objective, what changes by side, what ends the round, and what happens next. The source and check date should be visible.
If a source supports only a name, the entry stays here. If two names describe the same round, they should be reconciled rather than becoming duplicate pages. If the mode disappears from the current build, the page should record its dated status instead of pretending the route still works.
Modes FAQ
How many modes does Killer or Not have?
The official description confirms multiple modes, but no reliable complete count or list was available. Assassin is the only additional name confirmed through the official Place list.
How do I play Assassin?
The public first-party sources do not explain its entrance or rules. Use the current root-game interface and record the mode introduction if it routes you there.
Is Assassin a separate game?
It is a separate Place inside the same Killer or Not Universe, not an unrelated Universe according to Roblox’s official API.
What are the round win conditions?
They have not been reliably documented for each mode. Read the current objective and result screen rather than importing conditions from another game.
Why are there no mode child pages yet?
The audit approved those intents only after current rules evidence exists. Keeping the supported Assassin identity and verification route in this substantial hub avoids thin or invented articles.
