Last week, the long-rumoured Xbox version of the PlayStation Platinum Trophy , which Asha Sharma herself all but confirmed, popped up. It was spotted by X user Muse who noticed it in the available filters, and now more details have emerged about the Mythic Achievement.
TrueAchievements have the details, saying that a source has told them the new Mythic Achievement will roll out “soon.”
According to what TrueAchievements has been told, the Mythic Achievement is essentially the same as the PlayStation Platinum Trophy. Basically, a Mythic Achievement will be rewarded for completing all the other core Achievements in a game – no Achievements added via DLC or updates will count.
They also aren’t worth any GameScore.

Meanwhile, X user Krobrille claims to have found the new icon, animation an sound effect for the Achievement on the Xbox Game Pass PC app. It’s rather….dramatic, complete with its own soaring musical sting. Of course, this could be fake.
Jumping back to True Achievements, they claim that a players Mythic Achievement will be proudly displayed on their profile and will exist alongside the 100% completion highlight that was added a few months ago.
In fact, the entire gaming tab is getting an overhaul to highlight total GamerScore, Achievement total, your Mythic Achievements and more.
And once you earn a game’s Mythic Achievement, that game’s art in the Gaming tab will be decked out with a green star, laurel, and a green border.
Best of all, Mythic Achievements will be retroactively applied to all games, so once the update goes live you might find yourself with a nice collection.
