No More Room in Hell 2 Voice Chat and Callouts

No More Room in Hell 2 was built around proximity voice chat. The default VoIP link is hold E near teammates, and you can hear anyone within range without holding a key. Reading other callouts is just as important as making them. This page covers setup, etiquette, and the short callouts that keep a squad alive through a Scenario or Survival wave.

Quick setup

• PC: VoIP link key is hold E near teammates. Default mic input is your system mic. Open the audio settings on first launch.
• PlayStation 5: VoIP link key is hold L1 (default).
• Xbox Series: VoIP link key is hold LB (default).
• Cross-play: works between PC, PS5, and Xbox Series in the same lobby. Mic levels are independent per platform.

If your squad is missing voice chat after a patch, re-open Controls and Controller Settings to confirm your push-to-talk is still bound. The 1.0.3.1 hotfix reset keybinds; the 1.0.4.0 patch fixed controller scoreboard mute but did not re-bind any keys.

Tips & Tricks For New Players in No More Room In Hell 2

Proximity VoIP etiquette

Proximity VoIP only transmits to nearby teammates. It is not a global lobby chat. Use it for short, actionable callouts. Reserve global Discord or text chat for cross-map pings and post-match review.

Good etiquette:

• One-word status: “infected”, “ammo”, “down”, “clear”.
• Direction callouts: “runner behind”, “shambler front”.
• Objective progression: “key grabbed”, “at finale”, “extracting”.
• Medical urgency: “need pills”, “need therapy”.

Bad etiquette:

• Long monologues that block other callouts.
• Background noise, music, or keyboard typing that drowns out signal.
• Complaining in the middle of a horde — wait for the end-of-wave or extract.
• Unmuted griefers. Use the scoreboard mute (controller-fixed in 1.0.4.0) to deal with them.

Short callouts that work

These short callouts work across language and platform. Adapt to your language but keep them brief.

Situation	Callout	Why
Infected teammate	”Infected — pills?”	Triggers pill sharing before gene therapy timer runs out
Downed teammate	”Down at [location]“	Locates revive vs leave-behind decision
Runner spotted	”Runner [direction]“	Runner is fast and grabs from behind
Shambler / screamer	”Shambler front”	Screamers pull extra infected into the wave
Objective done	”Key at [player], moving”	Prevents duplicate effort
Helicopter ready	”Helo open, board now”	Triggers extract timing
Final extract	”Final wave, regroup”	Holds squad together for helicopter
Late save	”Down — need one”	Simple revive call

Sound discipline

Sound is the loudest signal in NMRIH 2. Zombies react to gunshots, melee swings, doors, and footsteps. Pair VoIP callouts with the sound cues your squad can hear.

• Gunfire summons hordes — coordinate shots during objective spikes, not during exploration.
• Footsteps matter — running toward a teammate alerts nearby infected. Approach quietly when a squad is holding.
• Doors are loud — close doors behind you to reset funnel positions.
• Listen for shambler screams — that audio cue means a wave is about to escalate. Pause looting, group up, save ammo for the spike.

Read Infected Types for which sounds each infected type makes so your callouts align with what your squad already hears.

Cross-play communication

Cross-play squads mix PC, PS5, and Xbox Series players. VoIP works across platforms in the same lobby. The friction points:

• Controller players default to L1/LB for VoIP link. KBM players default to E. Either party can rebind.
• Console players may have system-level voice chat features active. Disable system-level chat on the console itself so in-game VoIP is the only audio source.
• Deadzone changes announced for the September update will affect how mic input is interpreted if your controller has a push-to-talk mapping that uses stick movement.

After 1.0.4.0 fixes

Hotfix 1.0.4.0 fixed controller scoreboard mute, block, and report. That means controller players can finally mute griefers without leaving the lobby. Pair this with the proximity VoIP discipline above and your lobby communication will be cleaner than during launch week.

The Beyond Armageddon roadmap does not list major VoIP changes yet, but cross-play quality-of-life updates remain under active development.
