Proximity Voice Chat

Proximity voice chat has been added. You can now communicate with teammates and nearby players by voice in-game.

Voice chat is available in two modes: Team Voice and Global Voice. Team Voice can only be heard by members of the same Squad, while Global Voice is transmitted to nearby players regardless of team affiliation. Global Voice features distance-based attenuation, so audio becomes quieter as players move farther apart.

Join In-Progress Sessions

You can now join sessions with open slots even after a game has already started, within a set time window. The time window for joining in-progress sessions varies by mode: 5 minutes for Exploration mode, and 3 minutes for Survival and Hardcore modes.

When joining an in-progress session, you will enter the match directly without waiting in the start room. Joining players are placed at a spawn point with no other users or Zombies nearby, and a temporary invincibility state is applied immediately upon spawning for a safe entry. Additionally, mid-match re-entry into a session you have previously joined is not permitted.

Katana / Machete Guard Feature Added

A guard function has been added to the Katana and Machete as a secondary action (default: right mouse button). This allows for more aggressive defensive and counter-attack play with select Melee Weapons.

Interfloor Noise Removal

The Interfloor Noise system has been improved to reduce confusion and make positional awareness more natural.

• Footsteps, gunshots, and destruction sounds from destructible objects no longer transmit between floors.

• In stairwells, distance-based 3D audio is applied instead of removing interfloor noise.

• Elevator operating sounds remain unchanged.

New Boss: BigGuy

New boss BigGuy has been added. BigGuy appears in a new boss-exclusive level, accessible by using a specific item at the central staircase on B1F.

A new item, "Grade-A Researcher's ID Badge (Legendary)," has been added for entering the boss level. This item has a chance to drop upon defeating a Charger or Smasher, with drop rates varying by mode in ascending order: Exploration < Survival < Hardcore.

Bug Fixes

• Fixed an intermittent issue where the guard persisted while holding right-click in a guard-broken state.

• Fixed an intermittent issue where the guard UI was continuously displayed under certain conditions.

• Fixed an issue where the shutter rising sound did not play correctly depending on the timing of the shutter door opening.

Known Issues

• There is an issue where the game freezes intermittently when a Zombie's grab attack occurs in certain situations.

• There is an issue where some UI elements display abnormally when DLSS Frame Generation is enabled in the graphics options.

• There is an issue where, when wearing the new Armor 'Silent Zip-Up Jacket', some weapons and the Escape pod tracking device are obscured by the Armor in third-person view.

Important Notes:

• Matchmaking will be unavailable starting 30 minutes before maintenance begins.

• If maintenance starts during gameplay, there is a risk of item loss.

• Please be sure to safely exit the game before maintenance begins.

We will do our best to provide a better game experience.

Thank you.
