Serious Sam 4
Description
Buy Serious Sam 4 and receive 25% loyalty discount for Serious Sam: Siberian Mayhem!
Serious Sam 4 reignites the classic FPS series in a high-powered prequel loaded with an explosive arsenal, intergalactic carnage, and perfectly timed one-liners.
Humanity is under siege as the full force of Mental’s hordes spread across the world, ravaging what remains of a broken and beaten civilization. The last remaining resistance to the invasion is the Earth Defence Force led by Sam “Serious” Stone and his heavily-armed squad of misfit commandos.
Croteam returns with a high-powered prequel to the Serious Sam series that scales up chaos to unprecedented levels. The classic Serious Sam formula is revamped by putting an unstoppable arsenal up against an unimaginable number of enemies that requires players to circle-strafe and backpedal-blast their way out of impossible situations.
HORDES OF INVADERS
The iconic cast of alien invaders returns with some new reinforcements! Fight your way through unbelievable numbers of Mental's minions including the iconic Headless Kamikaze, Beheaded Rocketeer, Kleer, Scrapjack, Werebull, and Khnum! Square off against brand new enemies and towering monsters like the frantic Processed, repulsive Belcher, the hard-hitting Zealot, and more.
EXPLOSIVE ARSENAL
Armed with a slew of devastating weapons, pick your tool for any situation. Lay waste to Mental's Horde using the powerful double-barreled shotgun, the punishing minigun, the powerful chainsaw launcher, a brand new auto shotgun, and the iconic cannon. Upgrade your toys, and enjoy the violent beauty of the lock-on rocket launcher, and the mighty laser beam of death.
COOPERATIVE MAYHEM
Smash through the action-packed campaign with friends in 4-player online co-op mode! Tackle exciting primary missions and thrilling side quests in modified difficulties for an extra challenge.
LEGION SYSTEM
Serious Sam 4 unleashes some of the biggest moments in the series’ history with the new Legion System and battlefields teeming with thousands of enemies!

Mowing down thousands of aliens in Vatican City is worth doing at least once.

8/10
It may not top Serious Sam 3, but even then, this latest entry in Croteam's beloved series is still a winner. Serious Sam 4 is fast, loud, insane, and just straight-up cool.

4/5 stars
Serious Sam 4 doesn't deviate from the other entries in the mainline series, and that's perfectly okay. The fourth installment looks and handles perfectly, though some players may succumb to the repetition before the campaign concludes. That said, it's still an absolute blast to play, and it should keep fans busy for quite some time.

Maybe the CPU is the bottleneck?
I've been getting a solid 60fps at 1080p with an i9 9900k, 32 gigs of Ram, but a 1660 Super budget-gpu. The game has an auto-detect for graphics settings and I stuck with the suggestions. I had a crash to desktop while messing around in options, and LOD popup is noticeable in the slow parts, but I haven't had any of the awful bugs streamers complained of in the review build. Serious Sam 4 is more akin to Overload than nuDOOM. A recreating of classic FPS' gameplay with some modern refinements, but not the best gfx available at the time. It is not a radical reimagining. It looks like Serious Sam, it plays like Serious Sam, the level design is Serious Sam levels.

Great game with some small issues
This entry doesn't disappoint when it comes to action and obviously a silly story. At the beginning, the game starts a bit slow making you use very few and boring weapons. As you progress the game gets more entertaining, you get to kill hordes of creatures with different weapons. The normal difficulty is considerably hard to me. So to those who are new and don't wanna die a lot, easy mode is the best way to experience this crazy adventure. As for the issues, the textures load as you progress on my rig, also sometimes the autosave can be annoying when it loads you during a moment when you're about to die, and lastly, the loading times are somewhat slow, all of my games load pretty fast only this one makes me feel like I'm on an old PC. In general, I didn't experience serious glitches or slowdowns. Nothing prevented me from enjoying the game. It could've been 5 stars, but the issues are considerably annoying at times.

One of the Best SAM in the series
This must be one of the best installments of the Serious Sam saga, with a renewed interface and a lot of added lore, it goes a long way into Sam's history and experience, with the unmistakable humor that characterizes him and with new challenges, this installment will probably be the favorite of many.

Seriously loving it!!
Not sure why this game gets bashed. It's a damn good time. The guns feel great and the enemy variety make it a blast when the action is frantic. Best Serious Sam yet.
