Xbox Live Gold members will be able to play Sunset Overdrive for free for 24 hours starting tomorrow at 12:01 a.m. EST.
This is not a demo, but rather the entire game. Players will be able to earn achievements and save how ever far they progress for a full 24 hours. That said, if you manage to clear everything you want to clear within that time period, you don’t have to purchase the game. Otherwise, if you decide to later purchase the game, you’ll be able to pick up right where you left off.
Thanks, Major Nelson.
