Launchers, Updaters & Patchers

Branded launchers with fast patching and integrity checks.

Professional Lineage II launchers with delta patching, file verification, news integration and multi-client support.

The launcher is the first program a new player runs. If it's slow, janky or gets flagged by antivirus, you lose them before character creation. We build branded Lineage II launchers with binary delta patching, signed and integrity-checked files, embedded news and server status, and clean multi-client support - wired into the same API that powers your website.

What's included

  • Branded UI matching your server identity
  • Binary delta patching with resumable downloads and CDN support
  • File integrity verification against a signed manifest, with auto-repair
  • Code-signed, antivirus-friendly builds
  • Embedded news, banners and live server status
  • Multi-client launch and basic client hardening
  • Update pipeline and documentation for your team

Example work

  • Launcher with 2 GB client updating via a few MB delta
  • Auto-repair flow for modified or corrupted files
  • Injected-DLL detection with player warnings
