So Bethesda have decided to give current PC owners of Fallout76 the game for free on Steam.

Taken from the website:

"All you have to do to get your free Steam copy of Fallout 76 is go to https://bethesda.net/en/account/linked-accounts and link your Steam account to your Bethesda.net account before 11:59pm ET, April 12. When the Steam version is available, you will automatically receive your Fallout 76 entitlement."

Not sure if it counts as a deal but it's kinda free-ish.

Update: 16.04 Deal Extended to 28 April.
