Bioware is inviting would-be voice actors to submit a voiced set of lines from a script prepared by the Mass Effect: Andromeda team. Called "Explorers Wanted", the contest begins today and runs through September 28th with the winner set to be informed on or before November 30th.
All that is required is for potential actors to record their natural speaking voices using the prepared script. Winners will be brought to the studio for two nights to perform for Mass Effect: Andromeda.
Check out the details on the Bioware blog / Mass Effect: Andromeda site.
