You're probably wondering if dropping full price on Warhammer 40,000: Space Marine 2 is worth it for a story that most people finish in a single weekend. Honestly, the raw numbers on HowLongToBeat (HLTB) can be a bit deceiving if you just look at the "Main Story" category.
Look, Titus is a legend, but his latest crusade isn't an open-world epic that’s going to eat 100 hours of your life just to see the credits. It’s tight. It’s loud. It’s extremely focused. But if you’re the kind of player who uninstalls a game the second the credits roll, you're basically missing the actual meat of the experience.
Space Marine 2 HLTB: Breaking Down the Campaign Hours
If you’re just here for the main cinematic journey of Demetrian Titus, you’re looking at a 9 to 12-hour window.
That’s the standard. I’ve seen some speedsters clock out at 7 or 8 hours on "Easy" or "Normal," but that usually involves ignoring the scenery and sprinting through the Tyranid swarms. If you play on "Veteran"—which the devs basically suggest is the way it’s meant to be played—expect to push closer to that 12-hour mark. The difficulty spikes aren't just about enemy health; they force you to actually use the parry and dodge mechanics, which naturally slows down your progression through a mission.
One thing to keep in mind: the campaign consists of seven main missions, including the tutorial. While that sounds "short," some of these missions are absolute marathons. The final act alone can take you nearly two hours depending on how many times the Chaos forces kick your teeth in.
What about the "Completionist" run?
If you're hunting for every single Dataslate (those audio logs that flesh out the lore), you can add another 3 to 4 hours to your total.

Most people hitting the 15-hour mark in the campaign are usually the ones poking into every corner of the Hive Cities or stopping to admire the sheer scale of the Imperial architecture. Saber Interactive put a ton of work into the "background" of these levels—thousands of guardsmen fighting in the distance—and it's hard not to just stop and stare sometimes.
Operations and the "Real" Playtime
This is where the Space Marine 2 HLTB stats get wild. Most users reporting to the site are starting to log "Main + Sides" at around 20 to 25 hours, but even that feels low.
The Operations Mode is a series of PvE missions that run parallel to the main story. There were six at launch, with more added in free updates like the Reclamation Update (which brought us the massive Avarax cruiser mission). These aren't just "side quests." They are fully voiced, high-intensity missions where you play as your own custom-built Space Marine.
- Initial run of all Operations: ~6 to 8 hours.
- Leveling one class to Max (Level 25): ~15 to 20 hours.
- Maxing out all 6-7 classes: Easily 100+ hours.
Since each mission has four difficulty tiers—Minimal, Average, Substantial, and Ruthless—you aren't just playing the same thing over and over. You’re forced to optimize your build. If you don't have the right perks on your Thunder Hammer or Melta Rifle, Ruthless difficulty will eat you alive.
Eternal War: The Hidden Time Sink
Then there’s the PvP. "Eternal War" is 6v6 chaos. It’s got that old-school Gears of War or Halo feel where it’s more about positioning and brutal melee trades than twitch-reflex headshots.
Honestly, PvP is where the "Completionist" clock on HLTB jumps to 60 or 70 hours. You’ve got specific armor sets for the Traitor Legions (Chaos Marines) and the Loyalists to unlock. If you want your Heavy to look like a proper Blood Angel or your Sniper to sport Night Lords heraldry, you're going to be grinding matches for a long time.

Why "Short" Isn't a Bad Thing Here
We live in an era of 80-hour RPGs filled with "fetch five herbs" filler. Space Marine 2 doesn't do that.
The game is designed with a "New Game+" mentality even though it doesn't have a traditional mode for it. You’re meant to finish the story, feel like a god, and then take that energy into the co-op Operations to actually master the combat loop.
A Quick Reality Check on Stats:
- Solo Main Story: 9.5 hours (Average).
- Co-op Campaign: 8 hours (Everything goes faster with friends).
- Full PvE Content (Campaign + All Ops once): 16-18 hours.
- The "Dedicated" Player: 50+ hours (Leveling classes and weapon masteries).
Actionable Tips for Maximizing Your Time
If you want to get the most "bang for your buck" and ensure your personal Space Marine 2 HLTB doesn't end at the 8-hour mark, follow this path:
- Start on Veteran: Don't breeze through on Normal. The struggle makes the victory feel earned and extends the campaign naturally.
- Weave Operations into the Story: Don't wait until the end. After the mission "Severance" in the campaign, go play the corresponding Operation. It makes the narrative feel much bigger.
- Focus on one Class first: Don't jump between Tactical, Bulwark, and Assault constantly. Pick one, get it to level 10, and unlock the "Purple" tier weapons. The gameplay changes significantly when you have better gear.
- Check the Roadmap: Remember that Saber is adding a Horde Mode and new missions for free. This isn't a "one and done" title; it's a live game without the predatory microtransactions.
Ultimately, the time you spend in the 41st Millennium depends on how much you enjoy the loop of "shoot, parry, execute." If that loop clicks, you'll find yourself still playing at the 100-hour mark, long after Titus has finished his mission.
