Frequently Asked Questions – Assassin's Creed Odyssey (v1.5.3)
Is Assassin's Creed Odyssey completely free?
Yes, this version is available as a free download. However, it's a community repack, so it's not an official Ubisoft release. You can download and play without paying, but consider supporting the developers by purchasing the game if you enjoy it.
How do I install Assassin's Creed Odyssey?
Download the game files, extract them to a folder excluded from your antivirus, run the redistributables from the Redist folder, and launch the game using ACOdyssey_plus.exe as administrator. Detailed steps are in the Installation Guide.txt included in the download.
Why does the game ask for an activation key on Uplay?
Some configurations require Uplay (Ubisoft Connect) to be running. Install Uplay from the uplayinstaller in the uplay folder, launch Uplay first, then start the game. This usually bypasses the activation prompt.
My saves aren't working. What should I do?
Ensure you're running the game as administrator and that the save folder isn't read-only. Also, add the game folder to your antivirus exclusions. If problems persist, try running the game from a different drive.
