Saber’s Confrontation update just dropped new PvP maps and a fresh enemy type into Warhammer 40,000: Space Marine 2, but even loyal Ultramarines get tired of the same Operation loop after 200 hours. If you love the weighty melee, the swarm engine chaos, and the shoulder-to-shoulder co-op, seven other PC games scratch those itches at different angles.
We ran through each pick to compare weight, class variety, mission length, and how well they hold up on a Tuesday-night squad session. All of these Space Marine 2 alternatives run on Windows and most support Steam Deck.
Quick comparison

| Helldivers 2 | Chaotic PvE strat | 4 | $39.99 | Democracy-in-a-can |
| Deep Rock Galactic | Class synergy | 4 | $29.99 | Destructible caves |
| Warhammer 40K: Darktide | Grimdark melee | 4 | $39.99 | Same universe, first-person |
| Left 4 Dead 2 | Zombie shooter | 4 | $9.99 | Timeless directorAI |
| Aliens: Fireteam Elite | Bug swarms | 3 | $39.99 | Alien IP, dark aesthetic |
| Warhammer: Vermintide 2 | Fantasy melee | 4 | $29.99 | Same devs, medieval |
| GTFO | Slow-burn horror | 4 | $34.99 | Hardcore tactical |
Why Space Marine 2 players look elsewhere
A few things push people toward these alternatives:
- Operation fatigue. The PvE mission pool is finite. New maps arrive, but the loop feels familiar after enough runs.
- Class balance grumbling. Bulwark and Sniper still dominate patch discussions. Some players want a game where their preferred role feels first-class from day one.
- PvP wait times. Eternal War can queue for minutes at odd hours. PvE-first games avoid that entirely.
- Same-universe fatigue. Loyalist Marines are great, but a change of setting resets the palate.
Each pick below solves at least one of those.
The alternatives
Helldivers 2 — Best for chaotic PvE strategy
Helldivers 2 shares Space Marine 2’s obsession with wave clearing but plays it top-down-turned-third-person: you drop from orbit, complete objectives, and call in strategems while getting swarmed by Terminids or Automatons. The friendly-fire is unforgiving, the stratagem chain reactions are hilarious, and the meta-narrative (a “galactic war” that shifts weekly based on all players’ actions) keeps the loop fresh.
Where it falls short: melee feels weightless compared to Space Marine 2’s chainsword swings. If you play SM2 for the Titus-throws-a-Tyranid-across-the-map moments, Helldivers can feel too shooty.
Pricing: Base game runs about $39.99 on Steam. No subscription. Cosmetic packs are optional.
Migrating from Space Marine 2: Nothing transfers, but the “squad up on Discord, run a mission, laugh at chaos” workflow is identical. Give it two hours to click.
Download: Steam
Bottom line: Get this if you want scale and story momentum. Skip it if melee-first combat is your love language.
Deep Rock Galactic — Best for class synergy
Deep Rock Galactic is 4-player co-op where dwarves mine, fight bug swarms, and drink beer between shifts. Its classes (Gunner, Driller, Engineer, Scout) aren’t just weapon loadouts — they own literal terrain roles. The Scout lights the cave, the Driller carves paths, the Engineer builds platforms, the Gunner drops zip lines. It’s the tightest class-synergy shooter on Steam.
Where it falls short: graphics are stylized (low-poly cartoon), which some Space Marine 2 fans will find jarring after Titus’s photorealistic pauldrons.
Pricing: Base game $29.99. All post-launch seasons are free forever, funded by cosmetics.
Migrating from Space Marine 2: the “run PvE Operations with a fixed 4-stack” loop is nearly identical. Expect 30 hours before you feel you’ve seen the biomes.
Download: Steam
Bottom line: the best pick if you want tighter class interlock and permanent free content updates. Rock and stone.
Warhammer 40,000: Darktide — Best for grimdark first-person melee
Darktide is the closest tonal match: same universe, same hordes, same “swing a giant weapon into a wall of enemies” fantasy, but first-person and set in the underhive rather than a battlefield. Classes cover Zealot (melee-focused), Veteran (rifleman), Psyker (brain-frying warp caster), and Ogryn (giant with a slab).
Where it falls short: launch was rocky and some players still remember the crafting-system chaos. Later patches fixed most of it, but reviews are still “Mixed” overall.
Pricing: Base game $39.99. A season pass model has come and gone; current model is drip-fed free content plus cosmetic bundles.
Migrating from Space Marine 2: the transition to first-person takes a mission or two. Melee feels heavier here in exchange for less situational awareness.
Download: Steam
Bottom line: the direct fan crossover. If you want more 40K without leaving the setting, this is it.
Left 4 Dead 2 — Best budget zombie shooter
Yes, it’s from 2009. Yes, the AI Director still generates better mid-mission tension than most modern PvE shooters. Left 4 Dead 2 costs less than lunch, runs on any laptop, and has a Steam Workshop overflowing with community campaigns that give you effectively infinite content.
Where it falls short: dated graphics, tiny squad size (four players), no meaningful progression system. This is a pick-up-and-play shooter, not a live service.
Pricing: $9.99 base. Often $2 on sale.
Migrating from Space Marine 2: it’s a total tone shift (survivor humans, not superhuman Marines), but the “hold this position, wait for the chopper” beats are identical.
Download: Steam
Bottom line: the cheapest way to keep your squad session alive when Discord goes quiet.
Aliens: Fireteam Elite — Best for xenomorph fans
Fireteam Elite puts three players in Colonial Marine armor against Xenomorph swarms across four campaigns and a stack of expansion missions. It captures the Aliens film aesthetic well (pulse rifles that ping, motion trackers, atmospheric ship interiors) and the class system with Gunner, Demolisher, Technician, Doc, Recon, and Phalanx covers most co-op archetypes.
Where it falls short: community peaked in 2022 and matchmaking outside prime hours can stall. Bring your own three-stack.
Pricing: Base game $39.99. Season Pass Bundle for the DLC campaigns runs another $30 or so.
Migrating from Space Marine 2: three-player instead of four takes adjustment, but the mission structure (defend point, hold objective, extract) is very familiar.
Download: Steam
Bottom line: great for a fixed trio who love the Aliens IP. Skip it if you rely on public matchmaking.
Warhammer: Vermintide 2 — Best for melee-first fantasy
Same developer studio as Darktide, older engine, medieval fantasy setting. Vermintide 2 is the melee-first cousin of Space Marine 2: you play one of five heroes fending off Skaven ratmen and Chaos warriors with axes, hammers, and the occasional handgun. Combat weight and stamina management sit at the core.
Where it falls short: ranged play is deliberately weaker than melee. If you want to snipe from range, Darktide is a better fit.
Pricing: $29.99 base, frequently $10 on sale. Chaos Wastes DLC is free.
Migrating from Space Marine 2: the melee cadence — dodge, push, chain-swing — will feel instantly familiar. The fantasy setting is the palette cleanser.
Download: Steam
Bottom line: the closest melee analog to a chainsword-first Bulwark run.
GTFO — Best for slow-burn horror co-op
GTFO is the anti-Space Marine 2. Where SM2 is loud swarms and hero moments, GTFO is prisoners forced into hostile complexes to steal data, moving inch by inch, listening for enemies that swarm if you sprint. Every gunshot is a decision. It’s brutal, deliberate, and demands voice chat.
Where it falls short: high skill floor, unforgiving. Public matchmaking is essentially non-viable — you need a dedicated squad and headsets.
Pricing: $34.99 base. No microtransactions.
Migrating from Space Marine 2: think of it as playing Space Marine 2 on the highest difficulty with no revives, no ammo, and enemies that punish sprinting. Different rhythm entirely.
Download: Steam
Bottom line: the pick for a coordinated four-stack that wants co-op to feel like a heist film.
How to pick
- Pick Helldivers 2 if you want scale and meta-narrative. Ongoing galactic war keeps the loop fresh even after 100 hours.
- Pick Deep Rock Galactic if class synergy is what makes Space Marine 2 sing for you. Tightest team roles on this list.
- Pick Darktide if you want more 40K without leaving the universe. Direct thematic continuity.
- Pick Vermintide 2 if melee weight is the reason you play SM2. The chainsword cadence in a different setting.
- Pick GTFO if your squad wants pressure and silence. Not a filler pick — commit to it.
- Stay on Space Marine 2 if you love the third-person Marine identity specifically. Nothing else quite delivers that Titus fantasy.
