FATHOM Story Mode Guide

Start FATHOM Story Mode with clear Chapter 1 goals, automatic-save expectations, team roles, survival decisions, endings and badge planning.

Choose Story Mode when you want to investigate the shutdown of Fathom Amusement, complete Chapter 1, and reach the Go Home or Go Deeper choice. The official experience page says Story progress automatically saves, so the mode supports a careful session instead of demanding a single uninterrupted clear.

Story is also the route tied to Chapter 1 Complete and Untouchable. Use a first playthrough to learn objective flow and danger points. Protect a no-life-loss attempt only after the route and survival tools feel predictable.

Start with a session goal

Decide whether the group is playing blind, following a visual walkthrough, collecting one ending badge, or practicing for Untouchable. Mixing those goals creates frustration near the final choice. A blind group may want to stop a player from announcing later objectives, while a badge-focused group may want a specific branch.

Choose solo for complete control over pace and sound. Choose up to four players when shared observation is more valuable than silence. In a party, assign one objective reader and one person to watch the retreat. Use short callouts so microphone input does not become a constant signal to Grinsworth.

Before leaving the starting area, check the current prompts for interaction, camera flash, grapple, and any inventory controls. Public pages do not provide a reliable device-by-device key map. The live interface on your Roblox client is the useful answer.

Follow the objective and protect the return path

Treat each objective as a small loop: read it, identify the interaction, choose a landmark, plan the retreat, complete the action, and read the new text. This keeps a story run moving without requiring a fragile room-by-room script.

FATHOM’s official description says Grinsworth climbs walls and crawls through vents. When choosing a waiting spot, inspect above and behind rather than relying on one closed-looking corridor. A good landmark is easy to recognize from more than one direction and gives the team space to regroup.

If players separate, return to the agreed landmark instead of repeatedly calling positions. The threat hears footsteps, chat, and microphone voice. A lost player who produces continuous sound can turn a navigation problem into a group pursuit.

Use automatic saving correctly

Automatic saving means you can return and continue from saved progress. It does not publish the exact moment each checkpoint writes, whether a consumed tool is restored, or how a disconnect affects badge eligibility. After rejoining, inspect the current objective and available items before assuming the previous room was fully recorded.

When you need to stop, finish the current interaction and wait for any visible save or objective transition. Avoid leaving during a choice, pursuit, or reward animation. If the game provides no clear indicator, return later prepared to repeat a short section rather than risking a long unconfirmed sequence.

For Untouchable, a reconnect should not be treated as a way to erase a lost life. The official condition simply says to finish Chapter 1 without losing a life. Plan a clean run that does not depend on ambiguous checkpoint behavior.

Survive story encounters

Keep the grapple for a route you can see. Use the camera flash when Grinsworth is in front of you and the brief interruption can open an exit. Enter a locker only after breaking the immediate chase and becoming quiet. Using all three without a plan can leave the team empty-handed at the next objective.

If one section causes repeated deaths, change one factor. Reduce voice, move fewer players into the interaction area, reserve a flash, or map a different return line. The exact hearing range, blind duration, grapple distance, and locker rules are not public, so current visual and audio feedback should guide the adjustment.

After a chase, stop before returning to the objective. Count remaining tools, regroup players, and approach from a known direction. Story progress is easier to preserve when the team treats recovery as part of the route.

Handle Chapter 1 badges and the ending

The broad Chapter 1 Complete badge says that you climbed out of Chapter 1. Go Home and Go Deeper are separate official badges tied to the final choice. Read any end-of-chapter prompt slowly and confirm the party’s intended branch before selecting.

Public badge descriptions do not explain whether one choice awards every teammate, whether the branch can be replayed from a checkpoint, or whether both ending badges require full separate clears. If completion matters, plan for the possibility of another Story run and use the Chapter 1 Endings guide to keep the conditions separate.

Untouchable is a stricter layer on top of completion. A successful normal run should come first. Then choose the party size with the fewest unpredictable deaths, save defensive tools for known danger points, and treat any life loss as a reset.

When to use Story instead of Chase

Use Story when you care about narrative context, progression, ending decisions, or Chapter 1 badges. Use Chase when the group wants the hunt immediately or needs short practice with sound and escape tools. Chase experience can improve reactions, but it does not replace learning Story’s objective order.

Radar and Night Vision are officially described as available in Story and Chase but disabled in Nightmare. They can reduce navigation or visibility pressure, yet they do not solve choice prompts, checkpoint uncertainty, or badge conditions. Learn the normal Story route before deciding whether a convenience pass is worthwhile.
