Have an hour to kill and want a free copy of Assassin's Creed Odyssey? Google is giving a digital copy of the game to users who demo Project Stream, the search giant's venture into the world of online game streaming services. Project Stream is currently an invite-only program, but its free to sign up. If you can log an hour of gameplay before January 15th, Google will send you a download code for Assassin's Creed Odyssey via Ubisoft's Uplay service.
