For a shot at getting Assassin’s Creed Odyssey for free, head over to Stream and sign up to be a tester. Still, a free game is nothing to sneeze at. Interested gamers can sign up at Stream’s website, but it may be weeks before they’re notified of acceptance into the service (if they’re selected at all). That’s easier said than done, however Stream currently works on an invite-only system. To get their copy of Assassin’s Creed Odyssey (via Ubisoft’s Uplay distribution platform), testers will need to demo Google Stream for at least an hour. Google apparently needs testers for Stream to that end, giving away a digital copy of a game is likely cheaper than hiring testers through traditional methods.

In fact, Assassin’s Creed Odyssey is the only game available on the service. Nvidia, Sony, and a few other companies already have game streaming services available for a monthly subscription. Google announced Stream back at the beginning of October, but it’s unclear if the service will be fleshed out into a full retail product. Google Stream is the search giant’s entry into the budding world on online game streaming services. How’s this for an early Christmas present? Google is giving away digital copies of Assassin’s Creed Odyssey to gamers who demo Google Stream for an hour, completely free of charge.
