In-Game Tutorial

An in-game tutorial has been added to help new players get started.

The tutorial runs once immediately after character creation and is designed to help players learn the basic flow of the game.

Steam post imageAfter completing the tutorial, you can re-enter the tutorial and training ground from the lobby.

At the training ground, you can freely test your equipped loadout. Items obtained or consumed during the tutorial and training ground are not saved.

Workbench Renewal

The existing unified Workbench has been renewed into 5 separate Workbenches: Weapon, Armor, Recovery, Utility, and Materials.

Steam post imageThe Recovery Workbench, Weapon Workbench, and Armor Workbench are provided by default, while the others can be unlocked for use.

Each Workbench can be upgraded up to level 5, and the maximum craftable rarity is determined by the Workbench level.

Crafting-related conveniences such as quantity adjustment, craftable indicators, and current owned quantity display have also been improved.

Additionally, crafting time and queues have been removed, so you now receive crafted items instantly.

Workbench unlock status, level, and registered Blueprints are shared at the account level.

Steam post imageTo craft an item now, you must first obtain a Blueprint and register it at the Workbench.

• Defeating Elite Zombies (Elite Walker / Runner, Spitter, Howler) has a chance to drop Blueprints.

• Defeating Charger / Smasher has a chance to drop Blueprints.

• Weapon crates and iron crates also have a chance to drop Blueprints.

• Blueprint drop rates are higher in the order of Exploration < Survival < Hardcore.

New Mode: Hardcore Mode

A new PvPvE mode, Hardcore mode, has been added.

Hardcore mode requires an Item Score of 1,000 or higher and a character level of 15 or higher to enter.

In line with the higher risk, the chance of obtaining higher-rarity items is increased accordingly.

The types of items dropped are the same, but drop rates are tiered in the order of Exploration < Survival < Hardcore.

Steam post imageHardcore mode includes the base content of Exploration/Survival modes while featuring stronger zombies with red glowing eyes.

Additionally, killfeed information such as player kills, zombie kills, and Escape pod activations is not displayed.

Daily Mission System

A new daily mission system has been added.

Daily missions are automatically granted at 5 per day per character, providing recurring content where you can earn additional rewards through varied gameplay.

Daily missions can be progressed in actual play modes such as Rookie/Survival/Exploration, but not in the tutorial or training ground.

Steam post imageDaily missions reset at 00:00 UTC each day, and rewards for completed missions are delivered via character mail.

Additionally, completing a certain number of daily missions in a day grants extra rewards based on cumulative completion count.

Any rewards not claimed by the reset time will be automatically sent to your mailbox.

Missions you don't like can be changed using the reroll feature.

Reroll can only be used on incomplete missions, with up to 5 uses per day.

Approach daily missions flexibly to match your playstyle or current goals.

Balance Changes

Combat Balance

Skill Coefficient System Introduced

This update introduces a skill coefficient system and overhauls the calculation formulas for Armor Rating and Skill Power Resistance.

Previously, Skill Power was applied at the same ratio across various buffs and effects, making fine-grained per-skill balancing difficult.

Going forward, coefficients are separated by effect to allow more precise tuning.

• Each buff and effect now uses its own individual coefficient.

• Skill Power Resistance has been changed to reduce burn damage and Poison Damage (non-physical damage).

• Debuff Recovery Speed has been changed to multiplicative calculation.

• Skill Power and Skill Duration values are now displayed in integer units.

Armor Rating Formula Changed

How Armor Rating works has changed. At low Armor Rating values, the feel remains nearly identical to before, but at high Armor Rating values, damage reduction has been adjusted.

TTK (Time To Kill) in combat has been tuned to stay as close to the previous values as possible under the new formula.

• Armor Rating provided by each piece has been rebalanced to match the new formula.

• Armor Penetration, Armor Penetration Rate, and Armor Rating reduction values on items and character skills have also been adjusted.

  • Maximum item Armor Penetration: 20 → 30

  • Maximum item Armor Penetration Rate: 5.0% → 6.0%

Damage Type Changes

The damage types of some skills and items have been changed. After the change, Skill Power Resistance can partially mitigate this damage.

• CROW - Apply Poison, Vicious Strike, Poisoned Throwing Knife: True Damage → Poison Damage

• LOCKDOWN - Poison Gas Trap: True Damage → Poison Damage

• BARTENDER - Poison Shatter, Vicious Downpour: True Damage → Poison Damage

• Explosive Trap: True Damage → Burn Damage

• Molotov Cocktail: True Damage → Burn Damage

• World traps (electric zones): True Damage → Shock Damage

Weapon Balance Adjustments

• AdjustedShotgunFirearm-type Attack Power +12% increased, accuracy improved

Armor Option Changes

• Silent Armor Set: Throw bonus attack power 2 → 3

• Belt main stat: Armor Rating → Skill Power Resistance (up to 10% provided)

Zombie Difficulty Adjustments

• Attack power of regular zombies in Exploration and Survival modes has been reduced.

  • Walker: 45 → 36

  • Runner / Crawler: 46 → 37

Class Balance

This update broadly retunes skill effects and coefficients for each class. While maintaining each class's combat role, the structure has been reworked to allow more precise per-skill performance tuning. You can check detailed numbers for each skill by pressing Shift on the in-game skill tooltip.

BRICK

BRICK has been adjusted to strengthen pursuit and sustained engagement capabilities.

• A new passive skill'Sixth Sense'has been added.

  • AdjustedSixth SenseSkill Power Resistance increased by 45%.
• AdjustedDefense MasteryArmor Rating Increase Rate raised from 10% → 15%.

CROW

CROW has been adjusted to focus on poison and weakening effects, strengthening pressure capabilities after landing hits.

• Apply Poison, Vicious Strike, and Poisoned Throwing Knife damage type changed from True Damage to Poison Damage.

• AdjustedAssassinArmor Penetration increased from 200 → 300.

LOCKDOWN

LOCKDOWN has been adjusted to strengthen engagement control and trap-based pressure capabilities.

• Poison Gas Trap damage type changed from True Damage to Poison Damage.

• Trap Expert: Armor Rating reduction strengthened from -120 → -180.

BARTENDER

BARTENDER's support capabilities and debuff effects have been adjusted together for finer per-skill tuning.

• Poison Shatter and Vicious Downpour damage type changed from True Damage to Poison Damage.

• Corrosive Alcohol: Armor Rating reduction per stack strengthened from -20 → -30.

Economy Balance

Alongside the Workbench renewal, the overall economy structure has been adjusted. The flow of item acquisition, crafting, selling, and recycling has been reorganized to enable more meaningful farming and consumption.

Legendary Gear In-Game Drops

Legendary gear, which was previously supplied mainly through crafting, can now be obtained through in-game drops. Accordingly, the crafting system shifts toward enhancing existing gear.

• Defeating Charger / Smasher has a chance to drop Legendary gear.

• Weapon crates and iron crates in rooms entered using keys also have a chance to drop Legendary gear.

• All drop rates are applied higher in the order of Exploration < Survival < Hardcore.

Vendor Adjustments

Vendor economy balance has been broadly retuned to enable meaningful purchases and sales.

• Vendor Affinity transaction requirements have been reduced by approximately 30-40%, easing the difficulty of reaching higher levels.

• Sell-only items (junk, food) have had their purchase prices raised so that even Common rarity items are worth collecting.

• Crafting materials and Consumables (Drinks, Antibiotics, etc.) have had their purchase prices lowered to encourage crafting and consumption over Vendor selling.

• Other categories remain the same or have been slightly lowered.

Recycler Adjustments

• Overall recycling time has been shortened.

• Materials obtained from recycle-only items have been partially adjusted.

Mode Balance Adjustments

Mode balance has also been adjusted so that each mode's risk and reward structure is more clearly differentiated.

• Exploration and Survival are kept at the same difficulty, while Hardcore is set as the highest difficulty.

• The higher the mode's risk, the higher the item drop rates. (Exploration → Survival → Hardcore)

Mission Item Changes

Following the Workbench renewal, completion requirement items for some Vendor missions have been changed as follows.

• The Ultimate Armor Extracted cloth blueprint (Epic) → Uncommon fabric (Epic)

• What is Armor? 1 Extracted cloth blueprint (Rare) → Artificial leather (Rare)

• Shadow Threat 1 Extracted weapon blueprint (Epic) → Broken Melee Weapon Blueprint (Epic)

• Shadow Threat 2 Extracted cloth blueprint (Epic) → Leather (Epic)

World Update: Botanical Garden

Level design of the Botanical Garden area has been improved.

• Main pathways have been rearranged to simplify the previously complex structure.

• Lighting and environmental elements have been adjusted to ease the maze-like structure, improve visibility, and guide natural pathing.

• These changes reduce the cramped feeling and stress in the Botanical Garden area, broadly improving readability, convenience, and environmental storytelling during exploration.

Other Improvements

• Real-time notifications now appear when mission objectives are completed during in-game play.

• Real-time notifications now appear on the in-game screen for item acquisition, kills, and XP gain.
