Survival of the Fittest is arguably Phasmophobia's most challenging weekly challenge to date. The challenge strips away almost all your usual tools and protections, forcing you to rely on keen observation and quick thinking to identify the ghost.

This challenge takes place at 42 Edgefield Road, a claustrophobic house map that adds another layer of difficulty to ghost hunting and evasion.

Tips & Tricks for Completing Survival of the Fittest

This challenge presents unique limitations. You won't have access to standard evidence-gathering tools like the Ghost Writing Book, DOTs Projector, or even Video Cameras. Your equipment loadout is severely restricted.

Instead, you must rely on observing the ghost's behavior, movement speed, and visual model. Fortunately, some tools remain available. The Parabolic Microphone can help identify Banshees and Mylings through their distinct sounds. Salt can reveal a Wraith, and lighting three Firelights consecutively might reveal an Onyro. If you’re struggling, consult a cheat sheet detailing the behavioral clues for ghosts without traditional evidence.

You begin with zero sanity and no setup time (effectively five seconds), making you instantly vulnerable to ghost hunts. Sanity cannot be restored, even with the two provided Sanity Medications. Prepare for a high-pressure investigation.

Despite the lack of evidence tools, ghost activity remains high, with frequent events to aid identification. The ghost's favorite room remains consistent throughout the investigation. Most doors start ajar, hindering location deduction based on door states. However, the fuse box is functional and switched on—a rare advantage in these challenges. All nine hiding spots in 42 Edgefield Road are available for safety during hunts.

The only Cursed Possession available is the Monkey Paw. Using it to "wish for knowledge" eliminates incorrect evidence and ghost types from your Journal, improving your chances of guessing correctly. However, this comes at a significant risk: temporary blindness, deafness, and a nearby Cursed Hunt. This strategy is best suited for teams, allowing one player to act as a sacrificial distraction.

Accessing Challenge Mode

Challenge Mode is accessed through the Difficulty Settings in the Main Menu. Select Singleplayer or Multiplayer to create a lobby, then navigate to the Difficulty tab. Choose Challenge Mode and apply the settings. Remember to select 42 Edgefield Road on the map board. Completing the same investigation three times awards the full $5,000 reward (correct ghost identification is the only requirement).
