Publisher EA is offering a seven-day free trial of its PC free game library service Origin Access.

To take advantage of the trial, you have to sign up for a monthly (US $5 / £4) or yearly (US $30 / £20) subscription, but EA says if you cancel before the seven days are up, you won't have to pay a dime. It is not clear how long the offer will run for.

Origin Access is the PC version of EA's Xbox One subscription service, EA Access. The platforms offer a "Vault" of free games, including Battlefield 4, the Mass Effect trilogy, and Plants vs Zombies: Garden Warfare 2. Take a look at our complete list of all the EA/Origin Access free games.

In addition, EA/Origin Access members can play some games (but not all) ahead of launch; most of the time, subscribers get a five-day head start. One such game is Mass Effect: Andromeda, which Access members can play early, on March 16. Another benefit is that subscribers save 10 percent on all digital EA content.

No version of EA/Origin Access is on PlayStation 4. According to Sony, the service does not offer the kind of value PlayStation fans have come to expect. That being said, Sony maintains that it is open to having a dialogue with EA about how it might be able to bring EA Access to PS4 someday.
