DayZ Expansion Mod Guide

DayZ Guide • Updated Jan 16, 2026

DayZ Expansion

The "DayZ Expansion" mod is a massive overhaul that adds helicopters, boats, base building, and missions.

Modules

Expansion is split into modules so you don't have to install everything:

  • Expansion Core: Required for all modules.
  • Expansion Vehicles: Adds Helis and Boats.
  • Expansion Market: Adds trader zones.
  • Expansion BaseBuilding: Advanced base parts (codelocks, territories).

Installation Tips

Expansion is heavy. Ensure your server has at least 8GB RAM. You MUST wipe your server when installing Expansion for the first time to generate the map objects correctly.
