Mass Effect: Andromeda officially releases on March 21, but EA Access and Origin Access players can get access to it early. A 10-hour trial is now available, enabling people to begin playing through Andromeda's campaign and multiplayer.
This offer only applies to PC and Xbox One owners, as there's no "Access" service for PS4.
EA/Origin Access cost $5 per month or $30 per year. A subscription typically lets people access new games a little while before their full release and the subscriptions include a library of games.
On Xbox One, the game is 42.19 GB.
