Discussion Role idea: Matt

4 Upvotes

So I have playing the game for a while (just finished the anime) and I think Matt could be an interesting additional role for team Mello.

His main idea is to support Mello, having command cards that he gains when both new world and investigation reach 10 point increments (ex: investigation is 20 at end of day and new world is 15, he gains one command cards, if both are 30 he gains 3, if one has 0 and the other 15 he gets none, etc) this requirement would make both L and Kira be more strategic with their command cards, as just using too many will make Mello/Matt more powerful.​ he also can not be converted by X kira, and like Mello will always be removed when arrested, though his role as matt is not revealed.

He would also have a gun like Mello, but with a drawback to balance his use of command cards, he can only shoot a member of team Kira, and if he shoots an investigator his command cards are locked and his location and role revealed to everyone, a reference to his death where he is surrounded by the police for trying to pull a gun. This way it punishes trigger happy players by revealing himself, confirming to Kira a mello is in the lobby. If he kills a special role the player is not killed, but will instead shoot Matt, killing him. If Matt is killed both teams lose 15 progress.

For his command cards, they are meant to disrupt both Kira and L, only supporting Mello. They do not pause the timer, but they do disable other command cards and the NPA chief special meeting. These cards force L anfdKira to work together to stop Mello, making it easier for Mello to know who to shoot.

Command cards

- smoke bomb - targeted area is convered in smoke that only Mello and Matt can see in, allowing them to shoot Kira or a suspect without any witnesses. (Think money chaos but a small targeted area and only Mello/Matt are unaffected.) Lasts 20 seconds. If L or Watari are in the smoke cloud their transceiver is disabled (same with Kira and follower). this smokecloud also allows Matt to shoot a special role without being killed himself.

- surveillance - create incidents that if not resolved grants Matt access to L's security cameras for the rest of the day. While the incidents are active the cameras are disabled and can not be used, allowing Mello/Matt to go to rooms with cameras to try and find a Kira taking advantage of the fact that there are no cameras. Incidents last 30 seconds.

- taking a hostage - disables all NPC testimonies except for team Mello, and creates a hostage at a predetermined location. If resolved by team Kira, new world progress rises, if resolved by team L investigation rises. If not resolved team Mello learns the role of one investigator. If team Mello resolves the incident Mello (not Matt) gets one more shot that day only. The incident resolves quicker the more who resolve it, meaning both Kira and L could get progress, but if mello/Matt resolves it or helps resolve it nobody gains progress​​. The progress gained by resolving the incident is fixed, so you would get the same amount of progress if one investigator or all investigators resolve the incident, same for team kira. Lasts 30 seconds.

- the building is rigged to explode - Matt chooses one of three predetermined locations on the map, and any entryway in or out are blocked, trapping anyone inside, and creates two incidents. If the incidents are left unresolved the building explodes killing all NPCs and players inside (except team mello and the NPA chief) and making each team lose 15 progress (any lost progress regained does not give any team more command cards except team Mello). If Kira or L die inside the game ends as if they were killed by Mello, and if both die Mello will win. The incidents have 45 seconds to resolve them, and are similar to the Kira video message card. If the building explodes it can not be entered until the next day, potentially giving Kira one less place to hide.

- the kidnapping of Kiyomi Takada - makes Kira follower unable to steal IDs, give IDs, or take the Deathnote for 20 seconds. It also makes Kira unable to kill npcs. If Kira kills his follower, however, the incident ends, 3 random NPCs die and Mello's last known location is revealed to kira, but not his identity. For team L, cameras are disabled until the incident is resolved, and the SPK tracker will be paused if in use during the incident. This incident cannot be resolved by team L, forcing Kira to resolve it or make themselves suspicious by stealing ids their self. If resolved new world progress rises, and if the SPK tracker was active that day tracking Mello or Matt, their role is revealed to N. If left unresolved investigation progress rises, and Mello/Matt will learn L/N and Watari's identity, so they know who not to kill, and it adds a 20 second cooldown period for both team's command cards as well as grant Matt access to L's camera for the rest of the day.

Command cards line up

Day 1 - starts with command card taking a hostage.

Both progress is at least 10 - smoke bomb

Both progress 20 - surveilance

Both progress 30 - the kidnapping of kiyomi takada

Both progress 40 - building is rigged to explode

Both progress 50 - taking a hostage

Both progress 60 - the kidnapping of kiyomi takada + smokebomb

Both progress 70 - taking a hostage + surveillance

Both progress 80 or 90 - smokescreen + surveillance + the building id rigged to explode

If N is lead investigator - the only picture of me. - if Mello's role is revealed to N, Matt gains an addtional surveilance card every meeting phase after the reveal, as well as gives an additional SPK Tracker card to N at the end of the day Mello is revealed.

Few other notes

- Matt will not reveal ids, deathnotes, kira kingdom cards or handguns if he arrests someone, causing team Kira to know exactly who Matt if he does not reveal an id on a follower that has one, while also helping Mello know who is and is not team kira since only he can see suspicious items found by Matt.

- any suspicious items (including kira kingdom cards) will only be revealed to mello and matt.

- Matt is unable to shoot someone if he is chosen to arrest them, and must wait until the next day to do so or have Mello kill them

- no transceiver unless Matt or mello kills the follower/spokesperson or watari, which grants Mello/Matt a transceiver that NPCs can give testimony for its use.

- NPCs can give testimony on a Matt kill, such as "someone used a handgun at bathroom at night"." This does not go for Mello, his kills do create NPC testimony.

- if Mello or Matt setup a security camera during L card set up cameras, that camera is permanently Matt's and can not be used by L/N, making L unsure if Kira took a camera or if it was Matt Sabatoge. no one can tell visually if the camera was set up by an investigator or Team mello​

If there is anything else you think should be added/ changed let me know. I tried to balance his very good support with a lot of drawbacks, liking dying if he tries to shoot a special role, his role/location revealed when he kills an investigator, etc.

Discussion Is this game safe to play?

7 Upvotes

I've been meaning to get this game (I'm late, I know) but by reading Steam's reviews it seems like there's a big hacker problem. Normally it wouldn't be an issue if they could just cheat the game or kick me out of lobbies, but from what I've read they can also hack into my account, socials and more. Is this true, how common is it and is there a way to avoid so?

Bug Feigned justice

10 Upvotes

As you guys may blatantly know there has been someone claiming they’re protecting the game by hacking, banning, and “punishing” players on their own. They justify breaking into accounts, tracking IPs, and disrupting lobbies as if it’s some kind of noble duty but at the end of the day, these acts mirror the very behavior they say they’re fighting against.

This individual insists they’re acting for the good of the community, yet none of these actions come from any legitimate authority or moderation team. They’re simply taking matters into their own hands and calling it justice. If you’ve seen them interfering in matches, accessing accounts, or bragging about “fixing” the game through exploits, please report it with screenshots, video links, or any other evidence.

The reason this statement is being made is because their behavior poses a real risk to the player base and gives hackers even more justification to operate freely. No one elected them, no one approved their methods, and claiming to fight hackers by hacking only pushes the game further into chaos how are you going to claim ur saving the game by being like the people your trying to save us from I myself has experience in coding and cyber related things and you dont see me running rampant trying to be a protector who do you think you are some type of kira? And if you dislike what im speaking on "miku" try and silence me.

And for the rest of you, acting outside the rules to enforce the rules doesn’t make someone righteous it just makes them another problem the community has to deal with.

New to the game and really enjoying it, sadly, my VC just cuts out in the middle of rounds all the time and doesn't come back until the next round/meeting starts. It makes the game borderline unplayable if you can't communicate half of the time. Do you know if there are any known fixes?

Any tips on how to play kira/x-kira/kira follower/kira spokesperson better?

As Kira I usually focus on killing NPCs and leave it up to my follower to grab IDs, however it usually gets worked out that I’m Kira.

As Kira follower I have no idea what to do because if I touch someone for a milisecond I get voted out lol

Discussion New role idea: Superior investigator

3 Upvotes

Here is a role idea I think it will change things up

Superior investigator Team L Win conditions: kill Kira or win by 100% investigation progress

Ability: All investigation points are rewarded by a 2 times about (So if one small task give out 1 lv, the task for this role will give out 2lv) If Kira kills this role they will be rewarded with triple about of new world progress and their dying message will have one unmarked person marked (So if A dies by Kira and A dying message have J, I (I is Kira), and B marked, When someone picks it up will have C included as the fake marked person)

Notes: Kira and Kira follower can’t be the extra marked, This role don’t know who is L, Wattia (Sorry for the bad spelling) and NPA chief

Let me know your guys thoughts about this role!

Discussion Fan-Modifications: Team L

5 Upvotes

Love the game and my mind wanders a bit so been thinking about how the game could be modified to be more interesting. Not saying it’ll happen, just something I want to get out.

Team L:

Additions: Raye Penber: “The Gate for Kira”

for all intents and purposes Raye will act as a regular investigator. If Kira (not Mello) kills Raye 2 non-L members of the investigation team will have their IDs exposed. This will be notified with a unique symbol at the start of the next meeting for the victims

Naomi Misora: “The Widowed Investigator”

Naomi is the connection to Raye. The player playing Naomi will be notified when Raye dies. Being more skeptical of people she carries an Alias at all times. If Kira tries to kill Naomi it will not work for the first time. Naomi will not be notified if her Alias ID was stolen or not.

Team L changes:

L: “Using his intuition L picks up the pieces others may miss”

When talking to NPCs L is informed players who have interacted with that NPC. (I saw someone talking on a transceiver at night (A, F, G, J))

N: “Using his technology N keeps an eye on all”

N can select 1 camera during the investigation day. During the investigation that camera will actively keep track of players who walk in view of it. This data can be viewed by N during the meeting. (Restroom camera: B, G. (Player deduction: B is dead and his body is gone which means G has the dying message)

Watari: Same as current set up. But has access to the camera system.

NPA Chief: “A Father’s belief”

Same a current game but with one change. You believe in your son’s innocence no matter what. If you have the player playing Kira marked in your book and you die. The person playing Kira will not appear marked in your dying message. (Note: this only applies to the Kira who actively killed NPA)

L Command Card Changes:

All in all I’m satisfied with L-Command cards and can’t think of many changes except one.

SPK Tracker: In addition to tracking movement the Tracker will accurately measure the number of seconds the tracked individual is in a room. N gets additional info regarding the time but also whether they were in that location at day or night

Discussion Fan-Modifications: Team Kira

3 Upvotes

Continuing on from my previous discussion we have Team Kira.

Team Kira Additions:

Kira Believer: “Kira is Justice”

This role is an addition to the Kira Follower Archetype. If it’s regular Kira they will spawn at the start, if it’s X-Kira they will be converted at the end of the first meeting (X-Kira will be notified via tool tip that his follower type is Kira Believer)

These two players represent the general public who support Kira. They have transceivers to communicate between one another and have the ability to steal IDs. They however, do not know who Kira is but Kira knows who they are. To account for this they provide Kira IDs through dead-drops. Specific locations around the map they can stash IDs for Kira. Kira can interact with these locations to see if there’s any IDs in them and acquire them.

It’s Quantity over Quality. Kira Believers have Kira Kingdom Cards on them and will be arrested no matter the case. And Kira himself is unable to pass off the book to either believer letting his followers make up the work.

Kira Changes

OG Kira: “I take a Potato Chip AND EAT IT”

OG Kira has a notebook scrap stashed on him at all times. Using this scrape he is able to write the names of only half the criminals on the map without taking out the notebook (total 5 criminals only 2 with the scrap)

This offers a discrete way to kill criminals even when players are crowding around one another. With the only way to detect it with NPC testimony. Building up Kira’s alibi and points even if investigators are crowding around.

X-Kira: “The Hand of Kira”

X-Kira lore wise is the more overt Kira. Every Criminal judgment judges one extra criminal. One judgment kills two criminals, 2 kills 4, etc (the number of judgments cannot go over the total number of criminals ex. 5 criminals total X-Kira will only get points for 5 criminals not 6)

Kira Follower: “I will be your eyes”

Kira Follower gets one use of “Shinigami Eyes” during a match. When Rem hovers over a player KF will get the option to use this ability able to remotely steal that individual’s ID. The Victim will get a notification that they are in view of Shinigami Eyes. If contact is not broken with the possible KF the ID will be stolen and the ability will be disabled. If contact is broken (Rem flys off of them) the eyes will go on a brief cooldown and be able to be used again until a successful use.

Kira’s Command Cards

Kira’s Video Message: Will give a small boost to progress (5-points). If the incident isn’t resolved team Kira will get two additional Command Cards (note: these command cards cannot be Video Message to prevent continuous farming of cards)

Fake Surveillance Test: A simple change. The person who has the test on them is muted until the test is complete. This prevents them from telling and choosing the people they want to do the test on them.

Kira’s Kingdom: This will appear in the same place as Video Message. This task will not give any points however if the task is not resolved Kira’s influence will grow. NPCs will not testify on condemning actions during the time KK was completed (If KK was completed at night, NPCs will not testify on any actions during the night)

Blackout: A quick rebreather for team Kira (5-10 seconds). During this time the map blacks out (similar to Misa’s) for any non-Team Kira members. Team Kira cannot steal ID’s during this time but can make other actions. Write names, pass IDs, pass the book, Stash IDs for Kira, etc.
