4X strategy UA reckoning: what H1 2026 actually cost

The 4X strategy UA reckoning that analysts have warned about for a year finally showed up in the H1 2026 numbers. Naavik's read of the genre's first-half performance, published earlier this month, puts a figure on what most UA managers running these titles already felt in their auction data: the category's downloads and revenue both stalled after a strong first quarter, and the cause was not players losing interest so much as studios losing the ability to buy them profitably.

Naavik's analysis, which we are treating as secondary-sourced given its reliance on third-party tracker estimates rather than studio-reported figures, found 4X strategy downloads up 5% year on year across H1, adding roughly 18 million installs against a mobile free-to-play market that fell 12% over the same period. In-app purchase revenue for the genre rose 5% year on year too, about $193 million, while the broader F2P market slipped 2%. On paper that looks like relative outperformance. The detail that matters is what happened inside the half.

The reckoning, in Naavik's numbers

Naavik's figures show the genre's Q2 alone lost 27 million downloads and $195 million in revenue against Q1, drops of 12% and 10% respectively. The analysis attributes about 73% of that H1 revenue decline to acquisition-side deterioration rather than retention or monetisation problems, and pins roughly 92% of the download shortfall specifically on new-user acquisition slowing. That is an unusually clean attribution for an industry report to make, and it should be read as Naavik's model output rather than an audited fact, but it matches what buyers in the genre have been describing anecdotally since spring: rising costs per install for a shrinking pool of qualified 4X players.

Two structural pressures explain why buying became harder. First, the overall mobile download market contracted 12% year on year even as gaming ad spend rose an estimated 8%, meaning more budget chased fewer available users across every genre, not just strategy. Second, Naavik's analysis points to AppLovin and Google's AdMob together controlling around 75% of midcore ad revenue, a concentration that leaves little room for a 4X buyer to route around rising auction prices by shifting network mix. Newer subgenres, Match Merge 2-style titles and the sort-puzzle wave that has been picking up impression share through the year, compete for the same swipe-heavy, mid-session attention that strategy ads have relied on.

Last War's retreat is the tell

The clearest evidence sits inside a single title. Naavik's figures show Last War: Survival's quarterly revenue falling from roughly $406 million in Q1 to about $278 million in Q2, a decline that on its own accounts for close to two-thirds of the subgenre's quarterly loss. The studio is reported to have effectively turned off UA spend from May onward, with the game's impression share across major networks dropping close to zero, after reducing monetisation intensity in April in response to player feedback that spending pressure inside the game had become overwhelming. Read together, those two moves look less like a studio retreating from a bad market and more like a studio recalibrating a title that had been running both dials, acquisition and monetisation, harder than its player base could sustain.

Century Games' portfolio offers a contrast worth noting, again as Naavik reports it. Whiteout Survival and Kingshot are both said to have held revenue closer to flat through the half via ARPDAU improvements, even as new-user volume softened, which suggests a studio leaning on existing spenders rather than the acquisition engine to hold the top line. Last Z reportedly took a third path, cutting UA sharply earlier in the year before cautiously testing a return through TikTok and Moloco, a sequence that points to a studio still searching for a channel mix that pencils out at current costs.

What to check before assuming your own numbers

A UA lead running a 4X or hybrid-strategy title should not take Naavik's aggregate figures as a diagnosis of any single game, but the pattern is a useful checklist against your own dashboard:

• Whether your cost per qualified install has risen faster than your cost per raw install, which points to auction crowding rather than creative fatigue.
• Whether ARPDAU has held even as new-cohort volume falls, which would argue for pulling back acquisition rather than pushing it.
• Whether your top network's impression share for the genre has concentrated further this year, which changes how much leverage you have to negotiate CPMs.
• Whether your monetisation intensity has moved in the same direction as your UA spend over the past two quarters, since Last War's experience suggests running both harder at once eventually breaks retention.

None of this argues for abandoning the genre. It argues for treating H1 2026 as the point where 4X strategy stopped being a category that could out-buy its problems.

The auction pressure did not fall evenly

It is worth being precise about what "harder to buy" means in practice, because it is not the same story in every channel. A tightening download market with rising ad spend chasing it pushes CPMs up broadly, but the effect concentrates wherever the audience is already narrow. 4X strategy has always skewed toward an older, higher-intent player than most hybrid-casual genres, which is exactly the audience newer subgenres like sort-puzzle and Match Merge titles are also chasing as they mature past their own early, cheap-download phase. Two genres competing for an overlapping slice of mid-session, moderately monetising players will bid each other's costs up faster than a genre-wide download slump alone would predict. That is the mechanism behind Naavik's 92% attribution figure, even though the report itself does not break the number down channel by channel, and it is the reason a buyer cannot simply wait out a soft quarter and expect costs to normalise once download volumes recover elsewhere in mobile.

What comes next for the genre

Naavik frames the likely response as a shift toward what it calls a fifth generation of the genre, one built around differentiation and long-term retention rather than acquisition volume, though that framing is the analysis's own forecast rather than an announced industry direction. For a buying team, the practical implication is narrower and more immediate: budgets planned against 2025-era CPIs for this genre are already out of date, and the studios holding revenue through the second quarter did it by protecting existing players, not by finding cheaper new ones. Any Q4 plan for a 4X title should assume the cheap-download era for this genre closed sometime around May, and price accordingly.
