Update: After the Epsilon teaser, fans quickly discovered a link to another countdown under the name “Oculon-2819-Defiance” on EA’s official site. Oculon-2819-Defiance is listed as an access code here, the same as Epsilon, so it’s now looking pretty unlikely that either of these terms will be the official title of Mass Effect 5. It does, however, appear that we’ll be seeing several more teasers in this vein throughout the day.
