For mobile game studios with an established player base, re-engagement is one of the most direct paths to incremental revenue growth. Players who already know the game, have already made purchases, and have already demonstrated long-term value don't need to be convinced to start. They need a reason to come back.
Twin Harbour Interactive, the studio behind the Supremacy franchise including Supremacy: 1914, Call of War 1942, and World War 3, built their re-engagement strategy around that opportunity. With a growing catalogue of multiplayer strategy titles and an engaged player base, re-engagement sat alongside UA as a primary growth channel, with one KPI that mattered most: proving that spend was generating revenue that wouldn't have existed otherwise.
Sharpening the re-engagement strategy
In early re-engagement tests, Moloco and Twin Harbour learned key lessons that they took into the full roll-out. Instead of broad audiences, they focused entirely on paying users, those who had already demonstrated intent, willingness to spend, and the patience to learn a complex game.
Timing was also deliberate. The campaign ran from November 2025 through January 2026, timed to Q5 seasonality when lapsed players are most likely to re-engage, and sustained through Q1 to hold that momentum.
To measure what mattered, Twin Harbour ran the test through AppsFlyer with a formal holdout, their preferred method for isolating Moloco's contribution to revenue.
Creative built for reach, optimized for performance
The campaign ran across all creative formats, giving it full access to available supply and the broadest possible reach within a precisely defined audience. Moloco's team worked closely with Twin Harbour throughout, applying re-engagement best practices and optimizing in real time as performance data came in.
More formats meant more reach. More reach, combined with tighter targeting, meant more of the right users seeing the right creative at the right moment.
Twin Harbour’s incrementality testing showed meaningful uplift
The incrementality test Twin Harbour ran showed meaningful uplift: A 30.25% revenue lift at 92% statistical significance meant the campaign cleared the threshold they'd set from the start. At that significance level, Twin Harbour assessed the result as highly unlikely to be explained by chance or organic return. It was revenue the campaign generated.
The attribution metrics they saw reinforced the picture:
- D7 ROAS: 34.47%
- Session lift: +6.9%
- Session conversion lift: +8.09%
"The Supremacy franchise has been long-running, so re-engagement felt like a promising growth lever. We partnered with the Moloco team on retargeting, and they helped us get the targeting and creative strategy right. Seeing the incremental results confirmed it was working. Re-engagement is now a permanent part of how we grow," said Faisal Nimri from Twin Harbour.
Re-engagement is one of Twin Harbour’s key focus areas for 2026 and the company plans to continue building on this result with Moloco. With a proven measurement framework, a high-significance incrementality result, and a creative approach that can scale, the brand has a solid foundation in place for ongoing re-engagement efforts.
