Epic Games has announced You have just implemented a new feature in your store, Automatic Refunds. This means that it is now much easier to request a game refund. You just have to go to the payment history, in transactions, and if you meet the conditions you will see that you can request a refund. For it, It cannot have been more than 14 days
You have to be very careful before using this new function. If Epic Games believes that you are abusing the refund policy, or that you have not followed the terms of service, then may not allow you to request a refund. If you meet all the requirements, the money will be returned in a period of time that will depend on the payment method used.
Achievements and mod store
Putting aside automatic refunds, Epic Games has also said it is working to roll out a mod store in the future. In said store there will be mods made by gamers and game developers. Players will be able to automatically install the mods in those games they have purchased, which are managed by the Epic Games Store client, or download the mod files separately.
Regarding the achievement system, at present is in development and hope to be able to offer more information very soon. For now they have not given more details, they have only shared one capture.
