Steam DLC data: High attach rates for 2026 roguelike DLC
Roguelike fans are OBSESSED, so it's no surprise we're happy to fork out for DLC (it helps that the DLC is cheap!) Keep reading to learn which four 2026 roguelike DLCs sold over 100K copies on Steam.
We’ve already had some banging new roguelikes this year:
Slay the Spire 2 (6.5M sold on Steam, as per our estimates)
Mewgenics (1.8M on Steam)
Raccoin (550K on Steam)
Vampire Crawlers (coming up on 1M sold across platforms)
Saros (almost 350K on PS5), and the list keeps going!
Our estimates show that on Steam alone, the genre is already approaching $500M in gross revenue for 2026. Players are spending on roguelikes, but they’re also spending time. About a million people have already played Slay the Spire 2 for over 100 hours, and it’s only been in early access for two months.
So yes, we roguelike fans are obsessed with our titles of choice. Which is why it should come as no surprise that we also buy DLC for those games, and in droves.
Barony and CloverPit DLC both found their audiences
Four 2026 roguelike DLCs have crossed 100K copies sold on Steam this year, as per our estimates, with attach rates well above what we typically see for DLC across other genres.
Barony, a first-person 3D co-op roguelike dungeon crawler, dropped its first DLC in seven years this year. Barony: Deserters & Disciples launched at the end of January for $7.99, adding five new races and classes and a bunch of new ways to play the now-11-year-old game (where does the time go?).
Since then, our estimates show Barony: Deserters & Disciples has sold almost 200K copies on Steam, generating almost $1.2M in gross revenue. The core game on Steam has sold a little over 1M copies since its 2015 launch, so that’s an attach rate of over 19%. Pretty remarkable.
Last year’s CloverPit, the slot machine roguelike that’s shifted over 1.7M copies on Steam, also got a new DLC this year. CloverPit’s Unholy Fusion launched a little over a month ago and sold 129K units at its $2.99 price point. It had a peak attach rate of almost 8%.
Unholy Fusion has generated almost $300K on Steam. The base game has generated $12.7M, bringing our overall estimate to a round $13M. CloverPit was made by Italian studio Panik Arcade, and 13 is seen as a lucky number over in Italy. Love a bit of serendipity.
Of the 308K players who played CloverPit on Steam during the DLC’s launch month (April), 21% played Slots & Daggers and 20% also played Dice A Million, both recent roguelikes.
Our month-by-month audience overlap data makes it easy to surface these kinds of findings across Steam, PS5, and Xbox.
Monster Train 2’s first big DLC has done well, but Slay the Spire 2 has stolen its thunder a bit
Monster Train 2, a roguelike deck-building strategy game, launched a little under a year ago and completely took over my life. Since then, the base game has generated $10M in revenue on Steam via 525K copies sold.
Evidently, many of those players were hungry for more content. February’s $9.99 Destiny of the Railforged DLC has generated another $890K in revenue via 112K copies sold, with a peak attach rate of over 21%.
About two-thirds of Monster Train 2‘s player base has also picked up Slay the Spire 2 in early access on Steam, which had a noticeable impact on Monster Train 2‘s DAUs. You can see the pattern clearly in the data:
As you can see:
Monster Train 2 was averaging around 9K to 11K daily players through January.
The Destiny of the Railforged DLC launch on February 2 spiked DAUs above 27K and held the game in the 20K-28K band for almost two weeks.
Engagement then stabilised through the back half of February into the 13K-18K range, still well above the pre-DLC baseline.
Then Slay the Spire 2 entered early access on March 5, and Monster Train 2‘s DAUs collapsed to a new floor almost overnight, settling into the 5K-9K range and never recovering toward the pre-DLC baseline.
The timing here is worth flagging. Mega Crit announced back on 11 September 2025 that Slay the Spire 2 would slip out of 2025 into March 2026.
Monster Train 2‘s Destiny of the Railforged DLC was announced just a few days before its 2 February launch. You have to imagine the Slay the Spire 2 release date influenced Shiny Shoe’s planning for the DLC window.
Getting a major content drop out the door six weeks before the genre’s biggest 2026 release lands is the kind of timing call that looks obvious, but it’s genuinely hard to execute on.
If that was indeed what happened, our estimates suggest it was the right call. Without that February DLC spike, Monster Train 2 would have had a much quieter Q1 than it did.
Ravenswatch’s Merlin DLC has also done well, but it’s not without controversy
Finally, Ravenswatch‘s Merlin DLC launched on January 19 this year for $7.99. The base game has sold 1.2M copies ($17.8M) since its launch in September 2024, and the Merlin DLC has added another $662K to that number via 106K copies sold, with a peak attach rate of 9%.
Ravenswatch is a top-down, isometric action roguelite with a big emphasis on fluid combat and co-op gameplay. It’s a great game, and it’s overlooked a bit in the roguelike community. I digress.
The DLC sees legendary wizard Merlin join the Ravenswatch roster, including four skins that can be unlocked in-game, as well as three exclusive premium skins.
This is where our review sentiment data gets interesting. Our platform automatically flags review spikes (DLC launches being one of the main post-launch triggers), and the Merlin DLC produced a decent spike, with players pretty divided on it.
While the core combat, character variety, and co-op loop are widely praised, the decision to charge for a playable character in a premium-priced title that already features cosmetic DLC has driven most of the negative sentiment.
To many user reviewers, a paid playable character on top of paid cosmetics starts to feel like a model that fits a free-to-play game more than a premium one.
The audience is engaged enough to pay for DLC at meaningfully higher attach rates than other genres, but the same engagement makes them sharply attuned to monetisation decisions that can feel exploitative. T
Taking all four of these DLCs together, the picture is pretty clear. Roguelike DLC attach rates are running well above the Steam baseline for DLC, which typically sits in the low single digits across most genres.
Obviously, pricing is a lot of work for these chonky attach rates, with none of the DLC above $10 and the highest-performing by attach rate (Monster Train 2 at 21%) sitting right at that ceiling.
