Since Assassin’s Creed Odyssey uses automatic updates through official platforms, you don’t manually download a separate patch file. Instead, update through your game launcher: Steam:
| Platform | Method | |----------|--------| | Ubisoft Connect | Library → AC Odyssey → game automatically checks for updates | | Steam | Library → game → update will auto-download if enabled | | Epic Games Store | Library → Odyssey → “Verify” or let it update | | PlayStation / Xbox | System will prompt when you launch the game (requires internet) |
Do not download “update 1.5.6” from third-party websites — those could be malware or fake.
