From a client’s perspective running CPE campaigns, CPA directly impacts overall campaign performance and CV volume.
Using Doom’s Day as a reference, the data below illustrates how performance changes when accessing local media directly with the same budget.

App Overview
Doomsday: Last Survivors is a mobile simulation game set in a zombie-infested world where players build and upgrade their base (a “castle game” genre). This is a single-milestone reward campaign in which users must reach Headquarters Level 14 within 15 days. Compared to other castle games, the achievement condition is relatively lenient, with realistic completion possible in around 5 days at 1–2 hours per day.
Campaign Overview
- Genre: Simulation (Castle-Builder)
- Achievement Condition: Reach Headquarters Level 14
- Deadline: Within 15 days
- Billing Model: CPE — Single-milestone reward campaign where users receive the reward amount upon reaching the required level
- Estimated Time to Complete: ~5 days at 1–2 hours/day
- Difficulty: Moderate

Estimated Performance at $7,000 USD Budget (Both OS)
iOS / AOS
| CPE Campaign | Budget | Advertiser CPA | CV Count |
|---|---|---|---|
| Rocket A | $7,000 | $5.67 | 1,235 CV |
| Competitor A | $7,000 | $6.33 | 1,106 CV |
| Competitor B | $7,000 | $6.30 | 1,111 CV |
* Rocket A delivered 10.4% lower CPA and 11.4% more CVs vs. competitor average.
This week’s simulation reinforces a clear pattern: Rocket A delivers the most efficient outcome for advertisers, converting the same $7,000 budget into more conversions, at a lower cost, than either competitor.
At a $7,000 budget, Rocket A achieved a $5.67 CPA, roughly 10.4% below the competitor average of $6.32 (Competitor A: $6.33, Competitor B: $6.30). At the same time, Rocket A generated 1,235 CVs — about 11.4% more than the competitor average of 1,109 CV (Competitor A: 1,106 CV, Competitor B: 1,111 CV). This isn’t a marginal edge; it’s a clear demonstration of Rocket A doing more with the same spend, both in cost efficiency and conversion volume simultaneously.
What stands out here is the consistency across the competitive set. Competitor A and Competitor B post nearly identical CPA and CV figures to each other, hovering just below Rocket A’s performance on both metrics — suggesting the gap isn’t a fluke or a one-off outlier, but a structural advantage Rocket A holds over the broader competitive landscape at this budget level.
The core signal isn’t that Rocket A wins on price alone, or on volume alone — it’s that Rocket A wins on both at once. A lower CPA paired with a higher CV count at identical spend means advertisers get more qualified conversions per dollar with Rocket A, rather than trading cost efficiency for volume (or vice versa) as competitors’ near-identical figures suggest they’re forced to do.
When advertisers evaluate CPE campaigns, the instinct is often to chase the lowest sticker-price CPA. But Rocket A’s advantage isn’t just about being “cheaper” — it’s about consistently outperforming on both cost and volume at the same time, a combination that’s harder for competitors to replicate. That dual strength — a 10.4% lower CPA and 11.4% more CVs on identical budget — is what makes Rocket A a more reliable engine for scaling ad spend efficiently, rather than a campaign that only wins on one axis while sacrificing the other.
