It looks like both EA Access and Origina Access members on Xbox One and PC, respectively, will get a shot at trying Mass Effect: Andromeda a little early. Shortly after announcing the game's March 21 launch date, the official Mass Effect Twitter account confirmed the news, noting that it will be playable for a limited time.

In a follow-up, Mass Effect: Andromeda producer Michael Gamble also confirmed the game will be playable early on Origin Access as well.
It's not entirely clear just how early members of either subscription service will get access to the game. However, if it follows a similar pattern laid out for previous early trial launches for games like FIFA, it's likely subscribers will get to play for up to 10 hours a couple of days before the game's official launch. For what it's worth, Gamble did note that only a portion of the game will be able to play early.
If you're interested, you can subscribe to EA Access and Origin Access for $5 per month each, giving you access to early trials such as this, along with a number of full games from the EA Vault. Of course, Mass Effect: Andromeda is up for pre-order now as well.
