Murderthon Frost Guide

Frost is Murderthon’s winter-themed trial map, featuring a Mount Fuji rework that completely changed the original layout. This guide covers the new Frost architecture, the doorway gimmick system, generator routing in the cold, chase tiles that actually burn time, and how specific Masks exploit the environment. The map has undergone multiple reworks with door nerfs in recent patches, so this reflects the current state.

Use this guide alongside the West Park guide for map comparison, looping for chase fundamentals, and the killer guide for Mask-specific angles.

Map overview

Frost is an outdoor winter map centered around a Mount Fuji theme. The environment features snow-covered terrain, strategic cover points, and the signature doorway gimmick system that adds a unique strategic layer to the trial.

Key characteristics:

• Open sightlines similar to West Park but with different tile structures
• Doorway gimmick system that survivors and Mask can interact with
• Dense vent network (venting close duration increased to 30s for survivors, 16s for Mask)
• Cold atmosphere with holiday decorations during events
• Multiple generator islands spread across the terrain

How To Play Frost — Murderthon

Doorway gimmick system

Frost introduced a unique doorway mechanic that affects how survivors rotate and how Masks pressure:

How doors work:

• Doors can be opened and closed by both survivors and Mask
• Close duration: 10 seconds (reduced from 20s in recent nerf)
• Crouched players cannot trigger doors
• If a doorway has not been touched in 10 seconds, the pass count resets with a ticking audio cue
• A cooldown of 10 seconds activates after doors open

Strategic use for survivors:

• Block Mask rotation paths during chase
• Create safe rotation windows between generator islands
• Deny the Mask easy proxy camping positions
• Use doors to split up when the Mask is chasing a teammate

Strategic use for Mask:

• Close doors to cut off survivor escape routes
• Time door closures to trap survivors in dead zones
• Use door audio cues to predict survivor movement
• Block key rotations during endgame

Best door practices:

• Do not prep doors indefinitely—the timer resets with audio warning
• Communicate with the comm wheel about door states
• Treat door positions like pallet positions: limited resource

Generator routing

Survivors still need five of seven generators on Frost. The layout affects routing decisions:

Early game priorities

• Identify the safest generator clusters first
• Split between two islands when possible to deny Pierce teleport value
• Watch door positions before committing to a long repair

Mid-game decisions

• Protect high-progress gens during Mask pressure
• Use doors to create safe repair windows
• Avoid triple-stacking gens where Sheol ranged pressure or Lens camera coverage is strong

Late game

• Two gens remaining: use doors to block Mask rotation
• Gate phase: prefer the gate with better door coverage for retreat
• Last survivor: play for hatch, not vanity generator progress

Chase tiles and looping

Frost has several strong chase structures:

Snow-covered structures:

• Short walls with good vault angles
• Natural cover that breaks line of sight
• Multiple exit paths for survivors

Indoor sections:

• Tight corridors that benefit the Mask in close range
• Lockers available for stealth repositioning
• Generator rooms with partial cover

Open ground:

• Sprint across open snow only when necessary
• Crouch-walk to reduce scratch mark visibility
• Use terrain features for camera breaks

Mask-specific strategies

Mask	Frost angle
Pierce	Teleport cuts cold open ground crossings
Divide	Vent denial is strong; doors add another control layer
Sheol	Ranged cards shine in open Frost sightlines
Jammed	Cuffed survivors in open cold lose time walking
Fate	Trap door approaches and gen islands
Sin	Rush through doorways quickly; wall running removed
Ripe	Madness in open areas can scatter survivors
Lens	Camera coverage of open gens and doorways
Plague	Zone denial in generator clusters

Anti-camp and vent changes

Anti-camp to vents: vents close if you sit in them for 5 seconds. This affects both survivor and Mask vent usage.

Survivor venting close duration: 30 seconds (increased from 12s) Mask venting close duration: 16 seconds (increased from 12s)

This means:

• Survivors cannot abuse vents as heavily for escape
• Divide’s Lingering effect is even more punishing
• Mask can close vents more frequently

Common Frost mistakes

• Preppng doors too early without understanding the reset timer
• Sprinting across open snow (scratch marks light up)
• Ignoring door cooldown when rotating
• Triple-stacking generators in visible positions
• Not communicating door states with teammates
• Trying to loop in tight corridors against rush Masks

Practice checklist

1. Play two survivor matches focusing on door timing
2. Play one match noting which door positions matter most
3. Play one Mask match using Pierce to cut Frost crossings
4. Practice using doors strategically, not reactively
