If you haven't had the time to play Battlefield 4 yet, now is the best time to do so: EA has made their popular first-person shooter free on Origin for one week through their Game Time program, which previously offered up Titanfall through a similar deal.
To be clear, unlike the recent promotion offering The Sims 2 for free, EA isn't letting you download a free copy of Battlefield 4 that you can keep forever. Instead, you'll be able to download the entirety of the latest Battlefield title and play it for up to a week, after which it'll expire (unless you purchase it).
The week of free access to Battlefield 4 starts from the moment you launch the game for the first time after downloading it, with the clock ticking down regardless of if you play it or not. You will, however, have to grab the game before August 14th, when the Game Time promotion runs out.
Even though the Game Time program essentially gives you a free trial of Battlefield 4, you'll be able to play any part of the game you like, whether that's 64-player multiplayer or single-player. Progress is saved and stored, allowing you to continue playing after the week is over if you decide to pay for the game.
