Version & compatibility (mid-2026): the current Undead Legacy stable is UL 2.6.17, pinned to game Alpha 20.7 - and has been since 2022. There is no 1.0 or 2.x build yet; a next release, UL 2.7.01 targeting game v2.4, is in development but still listed as TBA. To play UL today you pin the A20.7 branch in Steam, or it will not load. It is not abandoned, just stagnant on an older branch - see the 2026 Mod Status Tracker. Author: Subquake.
Undead Legacy is a comprehensive 7D2D overhaul mod created by Subquake that transforms the game into a deep survival experience with emphasis on realism, crafting, and progression. The mod completely reworks core systems including item durability, weapon attachments, vehicle mechanics, electricity, and resource gathering.
The mod introduces a sophisticated crafting system where items have durability and require maintenance. Weapons can be customized with various attachments like scopes, grips, and extended magazines. Vehicles feature fuel consumption, part durability, and require regular maintenance.
Undead Legacy expands the technology tree with electricity systems, automated defenses, and advanced workstations. The mod also overhauls the zombie AI, adds new enemies, and introduces challenging environmental hazards that require strategic planning and resource management.

Undead Legacy is free (distributed by Subquake through his official channels and the 7D2D Mod Launcher - any site charging for it is a scam). Because the current stable runs on Alpha 20.7, version-matching is the whole job:
Mods/ folders into your game's Mods/ folder.For multiplayer the mod goes on the server and every client, all on A20.7. The flow mirrors a vanilla dedicated server setup: SteamCMD-install the dedicated server, pin it to the A20.7 branch, drop the UL Mods/ folders in, and run with EAC off (so UL servers, like other overhauls, are PC-only and not crossplay-capable). Prefer one-click? Managed Plan L hosting installs UL on the right branch and keeps it set up for you. Walkthrough video:
Does Undead Legacy work on V2.6? Not yet. The current stable, UL 2.6.17, is pinned to game Alpha 20.7; the v2.4-targeting 2.7.01 build is still TBA. Pin the A20.7 branch in Steam to play it. See the 2026 Mod Status Tracker.
Is Undead Legacy dead? No. It is a complete, highly polished overhaul - just stagnant on the A20.7 branch since 2022. Subquake has a v2.4-targeting build in development, listed as TBA.
Is Undead Legacy free? Yes. It is distributed free by Subquake through his official channels and the 7D2D Mod Launcher. Any site charging for it is a scam.
How do I install Undead Legacy? Back up your saves, pin the A20.7 game branch in Steam, install via the Mod Launcher (or extract the Mods folders manually), launch with EAC off, and start a fresh world.
Can I play Undead Legacy with console (Xbox / PS5) friends? No. UL is a PC-only overhaul and disables EAC, so it is not crossplay-capable. Everyone must be on PC, on the A20.7 branch, with the same build.
