10 Must-Play Games If You Love Space Marine 2

When Warhammer 40,000: Space Marine 2 burst onto the scene, it didn’t just meet expectations—it crushed them beneath an armored boot. The game delivered a visceral power fantasy that had players chainswording Tyranid hordes and roaring praises to the Emperor. But after the credits rolled and the final Chaos lord fell, a familiar hunger set in: where to find more of that adrenaline-fueled, grimdark mayhem? Whether it’s the tight co-op, the retro-styled carnage, or the sheer joy of purging xenos, plenty of other titles scratch the exact same itch. As 2026 offers more refined experiences than ever, here are ten games every Space Marine 2 fan should have on their radar.

Warhammer 40,000: Darktide

Space Marine 2’s Operations mode was a joy—tight, chaotic, and full of those “We’re going to die—wait, we survived?!” moments. For anyone who wanted that experience expanded into a full game, Darktide is the answer. This four-player co-op shooter takes a team of Inquisitorial agents deep into the hive city of Tertium, where they face relentless waves of Chaos cultists and mutants. Coordination matters as much as aim, with each class bringing unique abilities that can turn the tide. By 2026, Darktide has shed its early rough edges, thanks to a steady stream of patches, new missions, and a revamped crafting system. It’s a love letter to the 40K setting that’s best enjoyed with friends and a willingness to shout “For the Emperor!” at the screen.

Starship Troopers: Extermination

The Tyranids are terrifying, but sometimes a player just wants to squish bugs with a different flavor. Starship Troopers: Extermination pits 16 players against massive arachnid swarms on sprawling maps, tasking squads with building defenses, completing objectives, and, well, exterminating everything with more than four legs. It’s class-based chaos that rewards teamwork—engineers build walls while medics pick up the fallen and heavy gunners hose down the advancing tide. The game has grown significantly since its early access days, and by 2026 it offers a polished cooperative experience that feels like playing a big-budget sci-fi movie. If the idea of dropping a nuclear bomb on a hive appeals to you, this is a must-play.

Warhammer 40,000: Boltgun

Maybe the co-op wasn’t the main draw. Maybe what really got the heart pounding was stomping through a level as a lone Ultramarine, unleashing the Godwyn pattern bolter’s righteous fury. Boltgun strips away all modern pretense and delivers a pure ‘90s-style boomer shooter wrapped in 40K lore. Players dash and strafe through pixelated arenas, turning traitors and daemons into crimson paste with an arsenal that feels weighty and absurdly satisfying. By 2026, the game has added new difficulty modes and a horde survival mode that keeps the retro carnage fresh. It’s the kind of game that makes a Primarch proud—no reloading, just endless purging.

Ultrakill

If the 40K universe’s gleeful excess of violence is a selling point, then Ultrakill cranks that dial to eleven and snaps it off. This boomer shooter stars a machine that runs on blood, and the gameplay revolves around moving fast, hitting harder, and staying drenched in gore to survive. Parries, explosive weapons, and style-based scoring systems combine to create a rhythm of destruction that would make Khorne himself blush. The early access journey has been a wild ride, and in 2026, Ultrakill stands as a complete masterpiece of mayhem that rewards skill and aggression in equal measure. It’s the perfect game for someone who thinks Space Marine 2 could have used a bit more blood.

Doom Eternal

No conversation about hyper-violent action games is complete without the modern king: Doom Eternal. While Captain Titus is a diplomatic paragon of the Codex Astartes, the Doom Slayer communicates almost exclusively through gunfire and demonic screams. The combat loop is a furious ballet of weapon swapping, glory kills, and resource management that forces players to stay aggressive. Eternal’s encounter design pushes the player to the brink, only to empower them with ammo and health from fallen foes. With numerous expansions and a thriving community speedrunning scene in 2026, this game remains a benchmark for pure FPS adrenaline. If Space Marine 2’s combat felt satisfying, Doom Eternal will feel like home.

Helldivers 2

When it comes to third-person bug-squashing co-op, Helldivers 2 took 2024 by storm and has only improved since. Teams of up to four deploy onto procedurally generated planets to complete objectives while calling down orbital barrages, airstrikes, and heavy weapons that can flatten friend and foe alike. The friendly fire is on, the humor is pitch-black, and the emergent chaos is unmatched. By 2026, the Galactic War narrative has evolved through player efforts, introducing new factions and stratagems that keep the battlefield fresh. It’s less about an individual power fantasy and more about glorious, explosive teamwork—a perfect companion to Space Marine 2’s Operations.

Aliens: Fireteam Elite

On the surface, Aliens: Fireteam Elite looks like Space Marine 2 with Xenomorphs instead of Tyranids, but the tone is radically different. This game wants players to feel fragile, outnumbered, and constantly on the edge of disaster. The alien swarms are fewer but each Xeno is a lethal threat that can paint the walls with a careless marine. It’s a class-based third-person shooter that emphasizes positioning, covering fire, and desperate holds. By 2026, the game’s extensive DLCs have added new campaigns and modes, making it a deep, atmospheric dive into the Alien universe that’s perfect for players who enjoy tense, survival-oriented co-op.

Evil West

Swapping grimdark sci-fi for dark fantasy, Evil West offers an aggressively fun, vampire-slaying romp. Players control a grizzled cowboy armed with an arsenal of steampunk weapons and lightning-infused fists, carving through grotesque enemies in a stylish, ultra-violent fashion. The combat is a mix of third-person shooting and brutal melee combos, with environmental finishers and giant boss fights that feel ripped straight from a heavy metal album cover. It doesn’t take itself too seriously, and by 2026 it remains a hidden gem for anyone who loves over-the-top action and doesn’t mind a little collateral gore.

Remnant 2

After all the relentless shooting, a change of pace might be welcome—and Remnant 2 delivers a more methodical, souls-like approach to co-op action. Root-infested worlds and multi-dimensional horrors replace traditional demons, but the tension remains sky-high. Combat is deliberate, boss patterns must be learned, and survival depends on clever use of class perks and gear. The procedurally generated levels and branching story paths mean every playthrough feels different, and by 2026 the game has received substantial post-launch support, including new archetypes and a roguelike mode that extends replayability even further. It’s a game that rewards precision and perseverance, much like mastering the perfect parry in Space Marine 2.

Gears of War

It’s no secret that the Space Marine series drew heavy inspiration from Gears of War, and playing any entry in that franchise will feel instantly familiar. The chunky, cover-based gunplay, the roadie run, the visceral chainsaw kills—it’s all there, wrapped in a gritty war story. While Gears relies more on taking cover than charging headlong like an Ultramarine, the satisfying heft of the Lancer and the adrenaline of active reloads make it an ideal follow-up. With multiple mainline games and the latest installment from 2024 continuing the saga, players have a wealth of content to dive into. It’s the granddaddy of the modern third-person shooter, and it still teaches a masterclass in making combat feel impactful.

Whether it’s the cooperative desperation of Darktide, the retro frenzy of Boltgun, or the bombastic spectacle of Helldivers 2, there’s a vast galaxy of games waiting for players who’ve conquered Space Marine 2. Each brings its own flavor of violence, camaraderie, or grimdark atmosphere, ensuring the fight never truly ends. So load up, pick a target, and remember: they only outnumber you because the Emperor has blessed this slaughter.
