Shepard’s adventure may have ended in Mass Effect 3, but the Mass Effect universe lives on. Development of a fourth installment of the critically-acclaimed series may be closer to completion than originally thought, with Amazon already listing the Xbox One and PS4 versions of the game on its website. See it here. If Amazon’s listing is to be believed, the title will be released on December 31, 2014. Considering that Bioware hasn't made anything official, everything shown on the retailer’s website is likely a placeholder, including the box art. In fact, Canadian developer has confirmed that the next installment won't actually be called "Mass Effect 4." In the UK, Mass Effect 4 could cost anywhere from £40 to £65 (~$70 to $110), indicating that in addition to the standard package, there will also be a Collector’s Edition at launch. You can apparently pre-order the game.
