Serious Sam: Shatterverse is different from every Serious Sam game that came before it, and fans aren’t sure what to think. The fast-paced shooter series from The Talos Principle developer Croteam is known for its irreverent humor, large levels, and unique features like duel-wielding and vehicle-riding that set it apart from the likes of Doom, Duke Nukem, or any of the retro shooters that Nightdive has remastered.
