The amount of time for Battlefield 4? 168 hours of game time, or one full week. Or to put that another way, that's about half of my total play time in Battlefield 4, a game I've had since right around launch. Granted, I may suck, but that should give you a rough idea of just how many hours that really is.
Game Time for Battlefield 4 is the entire experience, available to play for one entire week. Go ahead, use your 168 hours of Game Time to complete the single-player campaign. Then jump into multiplayer and join your friends in 64-player warfare until the sun comes up… again and again and again. Your Game Time clock runs in real-time, whether you're in the fight or taking a break. but your progress and Origin Achievements will be saved if you want to keep your career going after your Game Time ends – buy the game and you’ll pick up right where you left off.
