Getting Started with 7 Days to Die Modding

Modlets, the Mod Launcher, and an XML-first modding scene anyone can author in

7 Days to Die modding is dominated by modlets — XML patches that edit specific game data files without conflicting with each other in most cases. The XML-first approach means installing mods is usually a file-copy operation, and writing your own mods is achievable with text-editor-level skills.

This guide walks the standard install path on the current 1.0+ release.

Step 1 — Confirm game version

7 Days to Die's official 1.0 release (mid-2024) reorganised significant XML schemas. Modlets written for Alpha 20/21 may not work on 1.0+ without updates.

Check your mod's compatibility tag before installing. Most popular mods have been ported to 1.0; some niche ones have not.

Step 2 — Decide: Mod Launcher or manual?

Two paths:

The 7D2D Mod Launcher is a community tool that manages multiple modded installs. Useful if you want to switch between vanilla and modded, or run different overhaul mods (Darkness Falls, Undead Legacy, etc.) in parallel.

Download, install, and let it auto-detect your 7D2D install. The Mod Launcher creates separate game copies for each overhaul mod.

Path B — Manual modlets

For lightweight modlet sets, you can drop them directly into 7 Days To Die/Mods/. Each modlet is a folder with ModInfo.xml at the root plus XML files in subdirectories.

This works fine for small mod sets but gets messy with 20+ modlets.

Step 3 — Install your first modlet (manual path)

Three popular first-mod picks:

  • Better HUD — UI mod, displays additional information.
  • Faster Stamina Regeneration — small QoL.
  • Auto-Pickup — picks up items in proximity without manual clicking.

Download (Nexus or 7D2D forums), extract the folder, drop into 7 Days To Die/Mods/. Launch the game; modlets are auto-detected and applied on load.

Step 4 — Larger overhaul mods

If you want a major change to the game, install through the Mod Launcher:

  • Darkness Falls — long-running zombie-survival overhaul with new classes, items, and progression.
  • Undead Legacy — alternative overhaul with different design priorities.
  • War of the Walkers — another overhaul, lighter touch.

These ship as full game replacements (the Mod Launcher copies the base game and applies the overhaul on top), not as drop-in modlets.

Step 5 — Multiplayer

Server-side mods require server-side installation. The dedicated server has its own Mods/ folder; the same modlets need to be there as on each client.

Clients with mismatched modlets get refused at connection. Use the Mod Launcher to coordinate matched modset profiles, or document the mod list manually.

Common gotchas

  • Modlet doesn't apply. Check the modlet's ModInfo.xml is well-formed. A syntax error in the XML can cause the entire modlet to silently fail.
  • Conflict between two modlets. Both modify the same XML node. The last-loaded wins. Modlet load order is alphabetical by folder name — prefix conflicting modlets with a sort prefix.
  • Pre-1.0 modlet on 1.0 game. Look for a 1.0-updated version, or test if the schemas it touches haven't changed. Most balance modlets are 1.0-safe; content-adding modlets often need updates.
  • Mod Launcher and manual install conflicts. Pick one path. The Mod Launcher's copy of the game is separate from your normal Steam install; mods in the wrong location are inert.
  • Random crashes after modlet install. Almost always a malformed XML edit. The game's output_log.txt (in Saves/ or the install directory) shows the parse error.

7 Days to Die's modding scene is one of the more forgiving entry points for new modders specifically because the XML-driven approach lets you make meaningful changes without writing code. If you've thought about authoring mods, this is a good game to start on.
