  description

  HOW IT WORKS
  • Browse any player's match history on aoe4world.com
  • Games with available replays show a "Watch Replay ▶" button
  • Click it to instantly download and launch the replay in AoE4
   
  FEATURES
  • One-click replay launching - downloads the replay and opens AoE4 directly into it
  • Works on game list pages and individual game detail pages
  • Save replays - star games on detail pages to keep them locally for offline viewing
  • Patch-aware - warns when a replay is from a previous patch, hides replays that are too old
   
  SETUP
  After installing the extension, download and run the native launcher from the GitHub releases page (linked when you first click "Watch Replay"). This small native host handles downloading replay files and launching AoE4 via Steam. It's fully open source and auditable - just a PowerShell script and a batch file.

  • Age of Empires IV installed via Steam (Windows)
  • The native launcher (one-time install from GitHub)
