Top Mobile Game Ad Creatives and Advertising Trends in January 2026
SocialPeta's January 2026 mobile game advertising analysis examines how Arknights: Endfield and Heartopia used high-volume creative production, video-first campaigns, localization, and staged user acquisition to compete across global markets.
Overview: Global Mobile Game Advertising in January 2026
In January 2026, SocialPeta analyzed global mobile games across advertising activity, downloads, and revenue performance on the App Store and Google Play. The month highlighted how both large-scale anime releases and lower-pressure lifestyle simulations could turn sustained creative production into significant market visibility.

The January campaigns also demonstrate that mobile game user acquisition is increasingly shaped by more than raw advertising volume. Creative format, localization, launch timing, gameplay presentation, and the fit between a game's core experience and its advertising message all influence how effectively a campaign can attract attention.
- Arknights: Endfield scaled aggressively around launch. The game deployed more than 16,000 deduplicated creatives across iOS and Android, with a major advertising burst surrounding its January 22 release.
- Heartopia demonstrated the strength of cozy, slow-life positioning. The title climbed free-download rankings in multiple markets while supporting its launch with a large volume of video-led advertising.
- Video remained the dominant creative format. Both games relied heavily on video, but their aspect ratios, messages, pacing, and featured gameplay reflected very different audience strategies.
- Localization remained central to global UA. Language distribution and regional campaign focus varied considerably between the two games, reinforcing the need to adapt creative strategy to target-market preferences.

Arknights: Endfield — High-Volume UA for a Global Launch
Arknights: Endfield became one of January's most visible global game launches. According to the original SocialPeta report, the game attracted intense industry attention after reports that it surpassed RMB 1.2 billion in revenue within two weeks of release.
The original article also discusses industry speculation around the contribution of global PC and PlayStation revenue. Those platform proportions were presented as rumored figures rather than verified SocialPeta measurements, but they illustrate why cross-platform performance became an important part of the market conversation surrounding the release.
The report compares this discussion with Infinity Nikki, another high-profile Unreal Engine 5 title for which global console revenue had previously been discussed in industry reporting.

Advertising Strategy Behind Arknights: Endfield
SocialPeta's advertising data shows that Arknights: Endfield did not wait until launch week to begin building demand. Its advertising history stretched back well before release, with the campaign expanding significantly during the game's third closed beta and accelerating again during the final pre-registration phase.
| Official launch | January 22, 2026 |
|---|---|
| Earliest detected ad placements | October 2023 |
| Large-scale promotion | Initiated during the third closed beta |
| Pre-launch warm-up | About 30 days |
| Total deduplicated creatives | Approximately 16,000 |
| Android share | More than 80% |
| Peak daily creatives | 3,702 on January 23 |
Video-Led Creatives Supported the Launch Burst
Video accounted for more than 74% of Arknights: Endfield creatives. Horizontal 640×360 formats were particularly common, matching the cinematic, open-world presentation used throughout the campaign.
English was the primary advertising language, with Traditional Chinese, Japanese, Korean, and other languages supporting additional markets. The resulting media mix reflects a global launch strategy built around a primary international campaign with localized execution for priority regions.
Creative concepts largely followed familiar patterns for premium anime-style open-world games: promotional-video montages, map transitions, character showcases, combat demonstrations, and influencer-led reactions or endorsements.
Rather than communicating every system in the game, many creatives emphasized instantly recognizable visual hooks. Character animation, exploration, combat spectacle, and distinctive character traits gave the ads material that could attract genre audiences within the first few seconds.

One example highlighted detailed and fluid character-tail animation, using a small visual detail as the creative hook for players interested in the game's character design and anime aesthetic.
The launch was not without friction. The original report references beta recharge-rebate arrangements, a temporary global payment issue, optimization concerns, and onboarding problems. Even so, Arknights: Endfield remained one of the most visible open-world anime releases of the period.
Marketing takeaway
Arknights: Endfield illustrates the value of a staged launch campaign: build awareness during testing, increase pressure during pre-registration, create a concentrated launch burst, and then continue promoting rewards and game content after release.
Heartopia — Slow-Life Gameplay Breaks Through the Charts
While Arknights: Endfield represented a high-budget global blockbuster launch, Heartopia demonstrated a very different path to visibility.
The slow-life simulation had reportedly spent eight years in development before its January launch. The original SocialPeta article characterized its rise as an underdog story: a cozy simulation product competing successfully for chart visibility against much larger productions launching during the same period.

Heartopia centers on a relaxed lifestyle experience combined with extensive DIY customization. Rather than depending on a mandatory main-story progression loop, the game gives players freedom to design and decorate homes while participating in activities such as fishing, cooking, gardening, birdwatching, and bug catching.

Marketing Performance of Heartopia
| Official launch | January 8, 2026 |
|---|---|
| Pre-launch campaign | Began in October 2025 |
| iOS ad placements began | October 14, 2025 |
| Cumulative advertising period | 121 days |
| January deduplicated creatives | Approximately 8,000 across both platforms |
| Peak daily creatives | 1,057 on January 15 |
Vertical Video and Gameplay-Led Creative Defined the Campaign
Video represented 97.33%of Heartopia's creatives, significantly higher than the already video-heavy mix used by Arknights: Endfield. Vertical 720×1280 creatives were the dominant format.
The format matched a campaign designed around approachable gameplay, social-feed consumption, and lifestyle-oriented visual storytelling. Instead of relying primarily on cinematic spectacle, the advertising showed players what living inside Heartopia's world could feel like.
Traditional Chinese accounted for approximately 46.39%of the detected advertising copy, while Japan represented the campaign's largest market in the original SocialPeta analysis.
Three creative directions appeared repeatedly:
- Direct gameplay demonstrations showing the relaxed daily-life loop.
- Customization and DIY content that made player expression easy to understand.
- Influencer-led and on-camera content designed to make the advertising feel more native to social feeds.


Marketing takeaway
Heartopia shows that strong UA does not require every creative to look like a cinematic trailer. When the core product promise is relaxation, customization, and everyday activity, direct gameplay and social-native creator content can communicate that value more naturally.
Key Takeaways for Mobile Game Marketers
- Creative scale still matters around major launches. Both cases used substantial volumes of advertising material to maintain visibility through important acquisition periods. High-volume production also gives teams more opportunities to test hooks, formats, characters, and messages across markets.
- Video remains the dominant mobile game advertising format. More than 74% of Arknights: Endfield creatives and 97.33% of Heartopia creatives were video. The campaigns differed, however, in how that video was packaged: horizontal cinematic presentation for one title and predominantly vertical social-feed creative for the other.
- Creative format should match the product experience. Open-world combat, character spectacle, and cinematic presentation suited Arknights: Endfield. Relaxed gameplay, customization, and creator-led content suited Heartopia. The best format is the one that communicates the game's real appeal efficiently.
- Localization is part of creative strategy, not just translation. Different language mixes and regional priorities shaped each campaign. Global UA teams need to consider which creative styles, formats, characters, and messages fit individual markets.
- A staged campaign can extend the value of launch marketing. Advertising can begin during testing, accelerate through pre-registration, peak around release, and continue through rewards, events, content updates, and feature-focused messaging.
Creative Volume Alone Does Not Explain Performance
The January examples also highlight an important limitation of creative-volume rankings: advertising activity should be interpreted alongside downloads, revenue, ranking movement, market distribution, and launch events.
To examine that relationship from the performance side, see SocialPeta's January 2026 mobile game revenue and download trends.
Looking at these signals together gives publishers and UA teams a clearer view of why a game is gaining attention and which parts of a competitor's strategy may be worth investigating further.
