The latest addition to Electronic Arts' Game Time promotion for Origin on PC is Battlefield 4, the most recent entry in the publisher's blockbuster shooter series. Game Time is a new promotional service that lets you play EA games on PC for free for a set period of time. In the case of Battlefield 4, you can play for an entire week, which comes out to 168 hours.

You have until August 14 at 10 AM PDT to add Battlefield 4 to your Origin game library. The Game Time clock starts when you launch the game, so the time you need to download and install it is not counted in the 168 total hours. Once you choose to start the clock, however, it will count down whether or not you're actually playing the game.

Origin Game Time for Battlefield 4 is not yet available everywhere, but it should roll out worldwide "over the next few hours," EA says.

If you decide to buy Battlefield 4 after your Game Time expires, your in-game progress is saved, allowing you to pick up where you left off. The Game Time promotion began in June with Titanfall, which was available to play for 48 hours.

Game Time is the second goodwill program EA has launched for Origin this year. It follows Origin's "On the House" promotion, which offers up a free game to keep. The current free game is Wing Commander III. Others have included Battlefield 3 and Dead Space.

The next entry in the Battlefield series is Battlefield Hardline, which was recently delayed from fall 2014 to early 2015.
