“In March 1996, the world was introduced to the first Resident Evil game, which helped shape survival horror as we know it and has since brought you some of the most loved games of all time. You’ve been able to play through the origins stories that started everything with the recent releases of Resident Evil and Resident Evil 0, and we’ve confirmed that a remake of Resident Evil 2 is on the way.

If you haven’t had a chance to play these yet or if you’ve been wanting to play them on your current consoles, we’ve got good news for you. Starting with Resident Evil 6 on March 29, all three games will be available for PS4 and Xbox One for an MSRP of only $19.99 / €19.99 / £15.99 each.
