01 / The Game

A Game Built on Immersive Social Dynamics, Personalities, Psychology & Relationships

TELL reinvents the concept of NPCs into living, breathing socially aware characters.

Using real human Big Five ‘O.C.E.A.N.’ psychology, interpersonal relationships and real-time procedural behavior, TELL’s characters are aware of their world and the people in it, and respond to what happens around them.

  1. 01

    NPC Awareness

    Non-player characters are aware of the people, objects and environment around them, and react according to their psychology, relationships and personality. Everything you do is scored behind the scenes and changes how characters respond to you.

  2. 02

    Make Choices

    Conversations branch on what you say, and nothing is forgotten. Every lie you tell is remembered by the person you told it to, and it comes back at the moment it costs you most.

  3. 03

    Question Liars

    Every character in town has a motivation and a life. Learn what makes them tick, find their ‘tell’, and call them on it before the killer gets ahead of you. But accuse a truth-teller or tip off a liar and you’ll damage the relationship and lose ground in your investigation.

  4. 04

    Explore the Town

    Investigate a small town in the North Carolina hills, in whatever order you like: the protagonist’s former high school, eerie backwoods cabins, secret rendezvous at motels, and the covered-up history of its landmarks.

  5. 05

    Build Relationships

    Everyone in town has an opinion of you that changes with every interaction. Trust, attraction, romance, contempt and collaboration are all weighted, and they shift with what you say and what people see you do. Forge friendships or lie your way to your goals?

  6. 06

    A Rich Story Built on Depth

    Written as a screenplay long before it was a game, TELL is a rich single-player story featuring a cast of characters with histories you may never uncover. Intended to speak to the human condition, it captures everything from adventure to romance, danger to introspection. See the world through Clay’s eyes, or bend him to your own.

Tellerman High, Summer 1996

Clay Mason was a brilliant high school student at the top of his class, aiming for a future at MIT, when his parents suffered a horrifying event in the backwoods of the North Carolina mountains. With his father missing and his mother traumatized and disturbed, Clay was forced to drop out of high school to provide income for the family.

Years later at 19, Clay has resorted to illegal means in order to make a living, until he is busted by a rogue police officer with an ulterior motive. Detective Bullock wants to recruit Clay to help him investigate a series of unspeakable murders by a smart, adapting serial killer with no known motive, before the killer murders his captive partner. Bullock needs someone who can sit across from a stranger and know they are lying, and Clay has been able to do that since he was a boy. For his partnership, Clay is given the chance at a GED and a real future, as well as to find out what really happened to his dad.

All leads currently point back to Clay’s former high school. Tellerman High is an old medical school, renovated into a modern lab for a post-high-school summer med program, with guest experts brought in from around the country. Hoping to find the next suspected victim, Tara Ashcroft, before the killer does, Clay must go in undercover as a pre-med student to learn what is really going on before the killer’s tracks are covered.

03 / The Tech

Built on FacialRAS

A prioprietary performance engine for MetaHumans, developed exclusively for this game.

FacialRAS is an Unreal Engine 5 plugin that drives MetaHuman performance procedurally: where a character is looking and why, what they feel, how their personality shapes what they show, and what leaks out when they try to hide it.

No motion capture. No per-character animation. It runs on a crowd.

Every tick in Tell, every NPC takes stock of their environment, concsiously or unconsciously and reacts accordingly based on a heierachy of interest points, characters, objectives or events. Their emotional reactions are genuine to who they are and their psychology.

  • Attention

    Eight-tier social arbitration. Characters notice what a person would notice, and look away when a person would.

  • Emotion

    A continuous emotional state shaped by personality, which drives the face, the posture and the breath. Nothing canned.

  • Concealment

    Characters mask what they feel, and leak it anyway. Masked smiles, suppressed tension, micro-leakage.

  • Conversation

    A director that stages scenes, handles interruptions, and resumes them the way real conversations recover.

The vocabulary

Real Human Psychology and Social Dynamics

Tell reflects real human psychology and behavioralism. Every face in the game runs on these logic trees.

The attention loop: characters noticing, and looking away.

Reticular Activating System

In people, the reticular activating system is the filter that decides which of the thousand things in a room are worth noticing, and lets the rest fall away. It is why you hear your own name across a loud party.

In TELLEvery character runs an eight-tier arbitration over everything they can perceive. Targets are scored by category, salience, distance and what the character thinks of them, then gated by how far that character can see and how far they care. A voice raises the priority of whoever is speaking, but only after a personal reaction time, so a group turns toward a new speaker in a ragged stagger rather than a synchronised swivel. Dwell, habituation and return-stickiness keep the eyes from flicking between equally interesting things.

The same line, performed by two different people.

The Big Five

Openness, conscientiousness, extraversion, agreeableness, neuroticism. The most empirically supported description of personality that psychology has produced.

In TELLEach character carries a value on every axis, compiled at load into runtime dials rather than checked at branch points. Neuroticism raises blink rate, saccade jitter and how easily fear takes hold. Extraversion scales how large expressions run and how much feeling bleeds into speech. Low conscientiousness widens gesture. Agreeableness slows how fast trust decays. Two characters given the same line and the same emotional state will not perform it the same way.

A composed face, and what escapes it.

Machiavellianism, narcissism, psychopathy

Three traits that describe how a person manipulates, and how well they conceal that they are doing it.

In TELLIn TELL they mostly govern masking. A character high in Machiavellianism suppresses negative expression while positive emotion is on show, so what you see is warmth and what they feel is contempt. The felt state is never overwritten, only the shown one, and that gap is what makes leakage possible: suppressed emotion escapes as micro-flashes, a lip press, tension on one side of the brow. High psychopathy also kills the Duchenne markers, the eye crinkle that separates a real smile from a worn one.

Establishing a baseline before the pressure starts.

Reading someone in seconds

People form accurate judgements of each other from very short observations, seconds rather than minutes. What thin slicing does not do is catch lies: deception accuracy across the literature sits barely above chance.

In TELLThat distinction is the whole game. The first read establishes a baseline, who this person is and how they behave when nothing is at stake. A tell is then a deviation from that baseline, not an entry in a dictionary of guilty behaviours. QUESTION is built on it: find the anchor, find the tell, bait the question, then decide whether you believe them. Because every baseline is generated from that character’s own personality, the noise is fair.

Trust and attraction shifting across a conversation.

Relationships that move

Attraction, trust and resentment are not a meter that fills. They are a running account of how someone has been treated, and they colour everything that person subsequently notices, feels and says.

In TELLEvery character holds a profile toward every other, yourself included: trust, attraction, contempt, collaboration. Those values change how strongly you register in their attention, what emotion the sight of you injects, and how they behave once a conversation starts. The game also keeps an append-only record of every lie you tell, per person. When their own story comes out, that record converts to trust damage, so a romance built on charm and lies collapses at precisely the moment it is revealed.

05 / The Creator

One person, a story decades
in the making

TELL is made by Matt Baamonde at Baazar Studios.

Everything running in TELL is original work created by Matt: the attention system, the emotion and personality model, the conversation director, the procedural face and body performance. All of it built from scratch, then used to make a game from an idea he wrote down decades ago.

Matt Baamonde started in music. He studied composition at Berklee, played guitar seriously enough to be good at it, and spent his first working years in music production and film scoring. A decade in Hollywood followed, across hundreds of TV shows and films in a range of creative roles, before he moved into visual work as an Unreal Engine VFX artist and character animator.

He now works in real-time virtual production, where rendering, animation and story get made in the same room at the same time. It is the part of the industry that changes fastest, which is why he is in it.

The skill set is deliberately wide: visual effects, graphic design, 3D animation, photography, video editing, music production. The music is the part that shapes how he works. Rhythm and timing are what make an animated performance read as alive, and he tends to hear them before he sees them.

TELL is the first project where all of it points in one direction.
