Yes. You heard it right GTA V is now FREE to play on the Epic Games Store. But you have to download the game before 21 May and it will be yours to keep forever. To get the game, you are required to enable 2FA (two-factor authenication) on your Epic account. You can use email as the 2FA if you do not want to provide your phone number.
The game will take up 95GB of storage from your PC. It will also download Rockstar Games Launcher. And you have to create a Rockstar account in order to play.
The version of GTA V that you will be getting is the Premium Edition of GTA 5. This includes a lot of additional content for GTA Online, as part of the Criminal Enterprise Starter Pack which gives you in-game currency worth $1,000,000.
If you haven’t made an Epic Games account yet, it might be worth considering making one now as Epic Games has been releasing a ton of free games weekly for you to keep forever.
