Survival of the Fittest is arguably Phasmophobia's most challenging mode yet. The challenge strips away nearly all your usual tools, forcing you to rely on instinct and observation to identify the ghost.

You'll face this challenge at 42 Edgefield Road, a claustrophobic house map that adds another layer of difficulty to tracking and evading the ghost.

Tips & Tricks for Completing Survival of the Fittest

This challenge presents unique limitations. Forget your usual evidence-gathering tools; you're starting without Ghost Writing Books, DOTs Projectors, or even Video Cameras.

Instead, focus on the ghost's behavior: its movement, model, and unique traits. The provided tools can help. For example, the Parabolic Microphone can pinpoint a Banshee's screams or a Myling's frequent noises. Salt can reveal a Wraith, and three lit Firelights might expose an Onyro. If you're struggling, consult a cheat sheet detailing no-evidence ghost behaviors.

You begin with zero sanity and no setup time (five seconds, technically), making you instantly vulnerable to hunts. Your two Sanity Medications offer little solace, as sanity cannot be replenished. Prepare for a high-pressure investigation.

Expect high ghost activity and frequent events. While frightening, this frequent activity can aid in identifying the ghost's behavior. The ghost will roam, but its favorite room remains constant.

Most doors start ajar, hindering location detection. However, the fuse box is functional and starts on, a rare advantage. All nine hiding spots in 42 Edgefield Road are available for safe haven during hunts.

Your only Cursed Possession is the Monkey Paw. Risky, especially solo, but "wishing for knowledge" can eliminate incorrect evidence and ghost types from your Journal, narrowing down the possibilities. This comes at the cost of temporary blindness, deafness, and a nearby Cursed Hunt. This strategy is best suited for groups, allowing one player to act as a sacrificial distraction.

Accessing Challenge Mode

Challenge Mode is a weekly event 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 select ‘Apply.’ Remember to manually select 42 Edgefield Road on the map screen.

Complete the investigation three times to earn the full $5,000 reward. Correctly identifying the ghost is the only requirement.
