Lethal Company Communication & Signals Guide: Walkie-Talkie Tips & Team Coordination (2026)

Last updated: May 12, 2026. All monster behaviors, terminal commands, and equipment mechanics verified against Lethal Company v69 (current stable build as of May 2026).

Quick Summary: Communication Essentials

Why Communication Determines Survival

In Lethal Company, poor communication is the number one cause of team wipes. A team with average mechanical skill but excellent communication will consistently outperform a team of skilled players who do not talk. The game deliberately creates information asymmetry — only the player who sees a monster knows it is there — making communication the critical link between individual awareness and team survival.

The Cost of Silence

Walkie-Talkie Mechanics

How Walkie-Talkies Work

Walkie-Talkies are purchasable from the Terminal for 100 credits each. They enable voice communication between players who are carrying them, regardless of distance, as long as both players are alive.

Walkie-Talkie Best Practices

1. Every player carries one — This is non-negotiable. Buy walkie-talkies before every expedition. If budget is tight, prioritize the Scout and the person staying at the ship.
2. Keep it in your hotbar — You need to switch to it instantly when danger appears. Do not bury it in your inventory.
3. Speak in short, clear callouts — Long monologues block critical warnings. Use the format: “What + Where + How many.”
4. Announce before entering rooms — “Entering room B2, left hallway” gives the team awareness of your location if your signal cuts out.

Monster Signal Recognition

Learning to identify monsters by their audio and visual signals is just as important as walkie-talkie communication. Many encounters give you a 2–5 second warning before the monster becomes lethal.

Audio Signals by Monster

Visual Signals

The Ship as Communication Hub

The ship is your team’s base of operations and the center of your communication network.

Ship Terminal Functions

The ship terminal is accessible via typing commands. It serves as both a management tool and a communication relay.

For a complete list of terminal commands, see our Terminal Commands Guide.

Using the Ship Monitor Effectively

The monitors command is your most important real-time communication tool. It shows:

1
2
3
4
5

PLAYER STATUS:
Player1 - ALIVE - Inside facility
Player2 - ALIVE - Outside (moon surface)
Player3 - DEAD - [no signal]
Player4 - ALIVE - On ship

Best practices:

• Check monitors every 5 minutes during a facility run
• If a player shows as DEAD, immediately inform the team and adjust your strategy
• If a player is ALIVE but not responding on walkie-talkie, they may be in a signal-dead zone or stunned

Team Coordination Tactics

The Buddy System

Never enter a facility alone. The buddy system pairs players so that every person has at least one teammate within walkie-talkie range and visual range.

Standard Callout System

Establish a consistent callout system before each run. The following conventions work well:

Pre-Run Communication Checklist

Before entering any facility, the team should confirm:

• All players have walkie-talkies equipped
• Roles are assigned (Scout, Carrier, Ship Guard)
• Meeting point established (usually the facility entrance)
• Emergency extraction plan confirmed (who activates teleporter)
• Scrap quota discussed (minimum target for the day)
• Time limit acknowledged (facility closes at a certain hour)

Equipment for Communication

Essential Communication Equipment

Using Equipment as Signals

Beyond their primary function, several items can serve as communication tools:

• Flashlight strobing: Quick on-off flashes mean “danger ahead.” Two flashes mean “all clear.”
• Boombox placement: Leave a playing boombox at a junction to mark it as safe or as a rally point.
• Stun Grenade: If you hear a stun grenade, it means a teammate is in combat — move to their position.
• Zap Gun: The electrical sound carries far and can signal that a Coiler or similar electrical threat is active.

Handling Communication Breakdowns

When Walkie-Talkies Fail

Walkie-talkies can fail in several scenarios:

Proximity Chat as Backup

When walkie-talkies are unavailable, Lethal Company’s proximity chat becomes your primary communication method. Proximity chat has a range of approximately 15 meters.

• Shouting increases range by about 50% but also attracts nearby monsters
• Use proximity chat strategically — only shout when the threat level justifies the noise risk
• Combine with flashlight signals for silent communication when monsters are nearby

Weather Effects on Communication

Weather conditions on different moons can significantly impact your communication strategy.

For detailed moon weather patterns, see our Weather & Conditions Guide.

Advanced Communication Strategies

The Relay System

On large maps, a single walkie-talkie chain may not reach from the ship to the deepest rooms. The relay system solves this:

1. Player 1 (Ship Guard) stays at the ship with a walkie-talkie
2. Player 2 (Relay) positions halfway between ship and facility entrance
3. Player 3 (Scout) goes deep into the facility
4. Player 4 (Carrier) works with the Scout

Player 2 relays messages between the Ship Guard and the Scout team. This extends your effective communication range across the entire map.

Silent Communication During Stealth

When monsters are sensitive to sound (Bracken, Nutcracker, Mouth Dog), use these silent signals:

Dealing with Public Lobbies

When playing with random players in public lobbies, communication challenges multiply:

• Assume no one has a microphone — Use the terminal signal command as a universal attention-getter
• Lead by example — Start making callouts yourself; others often follow
• Use the ship monitor aggressively — Check monitors frequently and announce status changes
• Be patient with new players — Explain the callout system once; do not spam warnings
