From Kotaku:
"Yesterday Bethesda added five classic titles to Steam, mainly from the Elder Scrolls franchise, including two of its lesser-known and more obscure spin-offs, Redguard and Battlespire. Here’s the full list.
The Elder Scrolls Arena
The Elder Scrolls II: Daggerfall
The Elder Scrolls Adventures: Redguard
An Elder Scrolls Legend: Battlespire
Wolfenstein: Enemy Territory
But not only are these now available on Steam, but some of them are free. You can grab Elder Scrolls Arena and its sequel Daggerfall for free. Plus, the online multiplayer shooter Wolfenstein: Enemy Territory costs 0 bucks at the moment. And while there isn’t any indication from Bethesda that these are temporary deals or mistakes, I’d suggest grabbing them ASAP just in case someone at Bethesda made a mistake during this big move back to Steam.
As a reminder, the Bethesda Launcher and store are shutting down for good on May 11. Starting tomorrow, April 27, Bethesda will allow players to migrate all of their games and wallet funds to Steam. You can read more about that via this recently updated FAQ Bethesda’s released ahead of the big close and move."
