Xbox is testing Mythic achievements, a reward for unlocking every base-game achievement, echoing PlayStation’s Platinum Trophy. The feature is currently limited to Xbox Insiders, with a wider release expected later; it matters as Xbox adds a completion milestone that players have requested for years.

Mythics exclude achievements from downloadable content and updates, and will be awarded retroactively, so players may receive them for games they have already completed. The article places the change in the history of achievement systems: Sony introduced PlayStation Trophies in 2008, after Xbox achievements helped popularise the idea, while Xbox has until now used Gamerscore as its main measure.
