According to Damjan Mravunac, the Serious Engine has been upgraded and Serious Sam 4 will take advantage of photogrammetry and motion capture.
"Nearly ten years after the first release of Serious Sam 3, Croteam and Devolver Digital finally released Serious Sam 4 on PC in 2020. One year later, an Xbox Series S|X version suddenly launched on Xbox Game Pass alongside PlayStation 5. While it’s great that console gamers can now enjoy the latest installment in one of my all-time favorite FPS series, major technical issues add plenty of unwelcome frustration to the console experience," says Co-Optimus.
Darren writes: "You know exactly what you're getting with a Serious Sam game, and Serious Sam 4 is no different. Issues aside, fans of the series should still have a blast with this one."
HPP: "Are you tired of carefully preserving ammo, cowering behind cover and taking measured shots? Serious Sam is back to save the day as he runs around like an Olympic sprinter, throwing highly explosive C4 around like rice at a wedding. The Serious Sam series is known for a less than entirely serious take on the FPS genre, showing an affinity for classic genre staples of wanton destruction seasoned with a goofily fun narrative."
When you think you aren't already outnumbered in previous Serious Sam games, they go and make that more intense
Can't wait
Love Serious Sam games. Although they need to take the franchise more seriously (no pun intended). By that I mean make the game more polished, bring some better design, better set pieces. Much of the SS3 was just a wide open are with a hundred enemies thrown in, I think the game could be much better if they craft it more.
