Gameplay changes on FIFA 20 focus primarily on a new feature titled VOLTA Football. The mode, which translates to 'return' in Portuguese, focuses on street football rather than the traditional matches associated with the FIFA series. It will include several options to play in three versus three, four versus four and five versus five matches, as well as with professional futsal rules. The mode will incorporate the same engine but places emphasis on skill and independent play rather than tactical or team play. Players will have the option to customise their player by gender, clothing, shoes, hats and tattoos. Following the completion of the three-part series "The Journey" in FIFA 19, players can now have a similar storyline mode in VOLTA Football, which would be played with the player's own character.

Changes will also be made to the traditional 11 versus 11 mode to encourage more one-on-ones and off-the-ball space creation. New penalty and free-kick mechanics will be implemented and updates will be made to the ball physics.

Career Mode, following feedback from the community, also received some substantial additions - mainly to the Manager Mode. New additions include fully interactive press conferences and player conversations, an improved player morale system which can affect the team or individual players stats, performance levels and stance with the manager. The ability to fully customise the managers appearance and sex (can be male or female), a new dynamic player potential system, live news screenshots, league oriented UI and new negotiation environments.

Whilst the Xbox One, PS4 and PC versions will have all of the new features, the Nintendo Switch version will instead be a Legacy Edition, with updated kits, rosters and minor updates, but without the new VOLTA Football mode or any of the other new features. FIFA 20 will not be released on Xbox 360 or PlayStation 3, making FIFA 19 the final game in the series to be released on those platforms.

15 new icons have been added to the Ultimate Team mode, including Didier Drogba, Ian Wright, Ronald Koeman, Andrea Pirlo, Zinedine Zidane and Carlos Alberto Torres. New game modes in Ultimate Team include King of the Hill and Mystery Ball. EA Sports writes, “Mystery Ball gives the attacking side boosts to their Passing, Shooting, Dribbling, Speed, or All attributes, adding an element of unpredictability to every match”. Meanwhile in King of the Hill, players “fight for possession in a randomly generated zone on the pitch to boost the amount your next goal is worth.”
