Although Amazon has digital copies of Mass Effect: Andromeda up for pre-order and lists a release date of December 29, 2017, a digital voucher spotted by game-industry persona "Wario64" indicates a launch of March 21.
There's an incongruity, however. The voucher reads PLAYABLE ON 21-MAR-2016. Given that the voucher is new, the year portion of the date is likely a typo.
Another possibility: a Photoshopped image devised to fool fans hungry for any scrap of news related to the next chapter in BioWare's Mass Effect saga.
BioWare has unleashed a torrent of Mass Effect: Andromeda news this week, primarily through the December issue of Game Informer magazine, on newsstands now. A cinematic trailer focused on humanity's struggle for survival, and creative director Mac Walters told GI editors that Andromeda is a standalone story rather than the first chapter in a new trilogy.
