Xbox decided to start releasing games on Game Pass without announcing them. Last week were added Townscaper e Generation Zero, in the subscription service, without prior notice. Now, Serious Sam 4, which was only available for PC and Stadia, had a surprise release on Xbox Series X/S, as well as a surprise inclusion in the Game Pass.
Serious Sam 4 is a first-person shooter in which you defend the earth from an army of extraterrestrial invaders. In addition to a single player campaign, the sniper alien also includes a cooperative mode for up to four players.
