Ahead of its September 29 launch, FIFA 18 has so far given us a "Ronaldo-fueled" reveal trailer and a star-studded teaser for The Journey's second season (see above). Today, EA Sports' annually updated footie sim drops a 12-team sporting demo two weeks ahead of kick off. 

The developer hasn't revealed exactly when the demo will arrive—"The launch of the FIFA 19 Demo varies depending on platform and location", so reads this update post—however it is due at some point today. When it lands, it'll come with 12 teams, four stadiums, and a preview of The Journey: Hunter Returns—the next installment Alex Hunter's rags-to-mega riches story.
