Core loop
How a FATHOM run plays
One loop repeats all chapter: read the objective bar, move without noise, and deal with Grinsworth when he closes in.
Read the objective bar
The line at the top of the screen names the current job and often the room to try next.
How the fuse objective readsMove quietly
Footsteps, chat and microphone input all travel to him. Crouch, and keep the callouts short.
What Grinsworth hearsBreak contact
Grapple away, blind him with the camera flash, or hold still in a locker until he loses you.
Four ways outTake the next objective
The bar changes as soon as a job finishes, so re-read it before moving on.
Chapter 1 objective order
Start here
Start where you are stuck
Four situations cover almost every first-week question.
The lights are still off
The objective bar says Get the power back on.
- Read the hint line
- It names the room to try, and it changes between runs.
- Watch the counter
- It reads Fuses found (x/3) and moves only when you pick one up.
He keeps finding me
You were caught and do not know what gave you away.
- Three channels give you away
- Footsteps, chat and microphone input.
- Four tools answer him
- Grapple, camera flash, lockers and, while he climbs, a flashlight.
I want to bring friends
You are setting up a co-op session.
- Four is the advertised limit
- The main place separately reports a 16-player server ceiling.
- Voice is a trade
- It coordinates the team and it also feeds the monster.

Store and game passesBefore you spend anything
The store mixes three product types and the names alone do not separate them.
Permanent passes
Three of the nine passes carry a PERMANENT prefix, so their effect survives a death.
The nine passesFor this run rows
The in-game sidebar sells Radar, Stronger Grapple and similar items for one run only.
Single-run rowsGifts
Developer products hand an item to another player. Gift Infinite Lives was listed at 175 Robux.

Read the first-run guide once, then play Chapter 1 with the objective bar in mind. Come back when a target stops making sense.
