01 / THE GUIDE
Teamwork and Communication
The mod supports co‑operative play for up to eight players, encouraging coordinated survival. Voice and text chat are distance‑limited, so staying close improves communication.
Players must share scarce weapons and ammunition, and decide how to handle infected teammates, making strategic choices essential for lasting longer.
- Keep your voice range short by staying near teammates.
- Use text chat for silent coordination when infection risk is high.
02 / THE GUIDE
Dynamic Objective Maps
Each playthrough features maps that change objectives, ensuring no two sessions are identical. This variability forces players to adapt tactics on the fly.
Map changes affect shelter locations, extraction points, and zombie spawn patterns, keeping the experience fresh.
- Explore early to locate new objectives quickly.
- Mark safe zones on the map to plan defenses.
03 / THE GUIDE
Survival Mode
In Survival Mode, teams must defend a shelter against waves of undead while awaiting extraction. Maintaining the shelter is crucial for survival.
Resource scarcity means ammunition must be conserved, and headshots are encouraged to eliminate threats efficiently.
- Set up choke points around the shelter.
- Prioritize headshots to conserve ammo.

Realistic Combat
The mod removes crosshairs and limits HUD elements, requiring players to aim down sights for accurate shooting. Weapons range from a .22 pistol to a chainsaw.
Ammo is extremely scarce, reinforcing careful aim and strategic weapon choice.
- Practice sight alignment before engagements.
- Reserve powerful weapons for tougher foes.

Infection Management
A single bite can infect a player, forcing a decision: reveal the infection for team removal or hide it while searching for a cure.
Infection adds tension, as infected players become a risk to the group.
- Communicate infection status early.
- Consider isolating infected players to protect the team.
