LINEAGE II
Sieghardt is LANMECCA's private High Five world: the familiar client and combat underneath, with our own quests, shops, experiments, and AI-assisted characters being built on top.
DOWNLOAD SIEGHARDT Windows 10/11 · launcher installerThe launcher inspects a High Five client that you already own, verifies its engine and complete native launch profile, creates a separate managed Sieghardt copy, requires the proven encrypted client route, and starts the game. It does not contain or reconstruct the Lineage II client itself.
Version 1.1 and newer check this site on startup. A new release downloads in the background, is verified against LANMECCA's separate release signature and its installer checksum. When it is ready, choose Restart and update; simply closing the launcher never installs anything unexpectedly.
Version 1.2 adds a second update channel for
LANMECCA-authored quests, scripts, configuration, and original assets. It
uses a different offline signing key, writes only launcher-owned paths,
verifies every file, and keeps a rollback transaction. NCSoft executables,
archives, GameGuard, and l2.ini are outside its ownership boundary.
This private build is not yet Authenticode-signed, so SmartScreen may show Windows protected your PC. Click More info, verify the LANMECCA checksum below, then choose Run anyway. A public signing certificate is the next hardening step.
What you need
- A compatible Lineage II High Five client that you sourced yourself.
- About 12.5 GiB free for a separate managed client copy and update headroom.
- Access to the LANMECCA network or its private tailnet.
- The launcher itself stays unprivileged. Windows shows one UAC prompt when the legacy game executable starts.
First launch
- Install and open Sieghardt.
- Use the compatible client the launcher detects, or choose another High Five folder. It accepts either the game root or its
systemfolder. - If it matches Baseline A and the proven Sieghardt route, choose a local destination and let the launcher copy only the required game directories. Your source and unrelated root tools remain untouched.
- Install the signed LANMECCA content set, let diagnostics finish, then press Play.
- A new username and password creates an account on first login.
The first qualified profile is the operational LANMECCA Baseline A. An unknown build or encrypted route is inventoried but never modified or launched. Additional variants can be added after their hashes pass real login and play testing.
