FATHOM Guide: Two modes to start from
About
OverviewFATHOM [HORROR] is a horror escape game set in Fathom Amusement, an underground theme park that shut down after an incident. You break in, something wakes up, and it can hear everything — your footsteps, your chat, even your voice on the mic. This guide covers how to survive, what tools you have, and how the game's two modes and Chapter 1 choices play out.

What the monster can hear
Warn
From the moment you arrive, the monster is already aware of you. It can climb walls and crawl through vents, so simply staying in one spot is not enough. Every sound you produce is a signal.
Three tools for staying alive
Step
You have three ways to push back or get away when the monster closes in.
- Grapple use this to move quickly along an escape route
- Camera flash point it at the monster and fire to temporarily blind it
- Locker step inside and stay completely silent when the monster is nearby
The Chapter 1 choice and its badges
Tips
Completing Chapter 1 earns you the Chapter 1 Complete badge and then immediately presents a decision. The path you pick changes what comes next and determines which badge you collect at that point.
- Choosing to go home earns the Go Home badge
- Choosing to go deeper earns the Go Deeper badge and continues into the park
- Progress is saved automatically, so you can return later and try the other choice in a separate run
- The Welcome badge is awarded simply for entering the park for the first time
Earning the Untouchable badge
Check
Untouchable is awarded for finishing Chapter 1 without losing a life.
- Keep footsteps to a minimum
- Avoid typing in chat or using your microphone unless the monster is far away
- Use the camera flash when the monster approaches head-on
- Duck into a locker any time the monster is near and you cannot escape
- Use the grapple to reach safety quickly

Common questions
FAQDoes my progress save if I leave mid-run?
Yes — the game saves your progress automatically. When you come back, you can pick up from where you left off without starting over.
Can the monster find me even when I'm hiding?
It can climb walls and crawl through vents, so it can reach almost anywhere. It reacts to footsteps, chat, and microphone audio.
Can I get both the Go Home and Go Deeper badges?
Yes, but not in the same run. Because progress is saved, you can reach the Chapter 1 ending again in a later session and choose the other option to collect the second badge.
Is it possible to play alone?
Solo play is fully supported.
