Hi. Is it possible to download Anthem to an external hard drive and play from there? Any tips for the best way to do that if possible?
It'd probably help if you indicated the platform you're planning to play on.
I play on Xbox, and Anthem runs from an external drive. I'm guessing you're talking about PC, however, since downloading to an external drive is automatic on the Xbox.
If you are on PC, you can change the location of your Game Library via the Origin menu, Application Settings, Installs & Saves.
