Much like Microsoft’s Xbox Gold and Sony’s Playstation Plus, Stadia Pro subscribers get free games every month. You have to grab them while they’re free, but once you do, you get to keep them so long as you maintain a subscription. In April, Stadio Pro gamers can pick up Serious Sam Collection, Spitlings, and Stacks On Stacks (On Stacks).
The nice thing about the Stadia Pro subscription is it essentially pays for itself. For $9.99 a month, you get a trio of games that would often cost you more to purchase on their own. Serious Sam Collection, for instance, currently goes for $30.
And in this case, the games you’re getting for free are fairly new to the service. The Serious Sam Collection arrived at the start of March and includes The First Encounter, The Second Encounter, and BFE.
You can pick up the games for free starting in April.
