Rebellion's co-op focused shooter is Stadia bound.
Zombie Army 4

On May 1, Stadia users will be able to buy and play Zombie Army 4: Dead War. In doing so, they will be able to play the game pretty much wherever they want to, provided they have Internet access. The Rebellion developed game allows for up to four players to go up against the legions of the undead.

These aren't just any typical undead here. These are undead nazis and are thus extra evil.

To sweeten the pot a little bit, Zombie Army 4 will be free to all Stadia Pro subscribers at launch. Google apparently has a free offer for a Stadia Pro trial going on right now, so maybe you can give that a go and play Zombie Army 4 with it.

The Stadia release will also include all of the previous released add-on content and DLC that has been released for Zombie Army 4 thus far. The game was released in early February for the PlayStation 4, Xbox One, and on PC but only on the Epic Games Store (affiliate link).
