Xbox's New Mythic Achievements Roll Out to Insiders, Showing How Close You Are to 100%

Mythic Achievements are officially rolling out to Xbox Insiders starting today, earned by unlocking all original achievements in a game, with DLC or update achievements not required. The system applies retroactively and adds a progress bar atop each game's achievement list showing how close players are to Mythic status. There's no date yet for when Mythic Achievements will leave the Xbox Insiders program for the rest of the Xbox userbase.
