The Epic Games Store is beginning to introduce an Achievements system for a limited amount of games. The feature is still in the early stages, and so only applies to a very limited amount of games as of right now.
The new feature was announced late yesterday evening through the Epic Games Store Twitter account. "Certain games on the Epic Games Store may begin to display achievements as you unlock them," the announcement reads. "This is an early version of the feature and you can expect to see changes and adjustments."
Epic then goes on to say that although this is a very early version of the Achievements system, they'll have more information to share in the future. For now, we can catch a glimpse of the feature at work for Ark: Survival Evolved, which takes the form of a pop-in horizontal bar on the right side of the screen, that shows you which Achievements you've already unlocked, and which Achievements you've yet to accomplish. There's no word yet on which additional games Epic is planning to implement the Achievements feature for.
It's weird to think that the Epic Games Store only launched in December 2018; it feels like it's been around forever at this point. This is just the latest in a series of improvements and additions Epic Games is making to its PC launcher: earlier this year in March, Wishlists were added for the first time.
Later on in May, Grand Theft Auto 5 was the latest high-profile giveaway through the Epic Games Store. The demand for the 2013 game was so massive that the store couldn't actually cope, and ended up crashing out a number of times on the day of GTA 5's free release for PC players.
