When Vision Meets Execution
In the competitive landscape of game publishing, where first impressions are crafted in seconds, User Acquisition (UA) videos are more than just marketing tools, they’re gateways into game worlds. Thunder Cloud Studio’s enduring partnership with Yoozoo Games stands as a global benchmark in producing compelling, high-converting UA videos. Combining AAA game art outsourcing excellence with storytelling finesse, this collaboration showcases what’s possible when trust meets talent.
Trusted by Yoozoo and Global Publishers: Why Thunder Cloud Is the Go-To Partner

Yoozoo, the powerhouse behind globally recognized titles like Legacy of Discord, League of Angels: Heaven’s Fury, Infinity Kingdom, and recent releases such as Metal Slug: Awakening and Saint Seiya: Legend of Justice, is ranked among the top 10 mobile game publishers in China. With a growing global footprint and a track record of successful IPs, Yoozoo required more than a vendor, they needed a trusted partner who could consistently deliver visual excellence, meet tight deadlines, and understand the nuances of both stylized and realistic game art.
With a proven record of servicing elite publishers like Yoozoo, Scopely, and MTG, Thunder Cloud has earned its reputation globally for production flexibility, artistic range, and consistent delivery. From character rigging and animation to environmental VFX and real-time in-game cinematics, Thunder Cloud covers the entire pipeline with technical precision and creative agility.
Unreal Engine is not just a tool we use, it is our primary platform, backed by a talented team of engine artists with years of experience in crafting stunning, high-performance visuals. Our multilingual teams and streamlined communication enable seamless delivery across time zones, a critical advantage when working with global publishers.
The Impact of UA Videos in Global Game Marketing
User acquisition videos are now core assets in mobile and online game marketing. A well-crafted UA video not only attracts users but directly impacts retention and conversion rates. Thunder Cloud’s approach blends:
- Cinematic storytelling: Drawing users into the game world in under 30 seconds.
- Stylized consistency: Ensuring brand integrity across game series like League of Angels.
- Technical precision: Real-time rendering, seamless transitions, and optimized assets for mobile platforms.
Each project with Yoozoo was a high-stakes opportunity and Thunder Cloud delivered every time.

Flagship Projects: From Legacy of Discord to Game of Thrones

Some standout collaborations include:
1. Legacy of Discord
An early collaboration that marked the beginning of a productive creative relationship. Thunder Cloud contributed cinematic visuals that supported user engagement during its launch phase.
2. League of Angels Series
Thunder Cloud worked on various installments in the League of Angels franchise, helping to maintain visual cohesion while aligning with evolving stylistic goals.
3. Game of Thrones: Winter is Coming
A realistic in-game trailer showcasing Thunder Cloud’s capacity to work within a high-fidelity visual universe while managing complex animated sequences and effects.
4. Infinity Kingdom
Thunder Cloud provided both a flagship cinematic trailer and a series of user acquisition (UA) videos, leveraging Unreal Engine to produce stylized action that matched the game’s tone.

Behind the Scenes: How Thunder Cloud Produces UA Video Excellence

Our UA video production pipeline includes:
- Storyboard and animatic for visual direction
- 3D asset preparation and character rigging
- Scene animation with camera direction tailored to user flow
- Post-production
Clients can enter the pipeline at any stage. Whether providing a complete storyboard or just written concept notes, Thunder Cloud’s team adapts accordingly, ensuring seamless progression through all phases. Unreal Engine is our studio’s primary production engine, supported by a veteran team of engine artists with deep expertise in building real-time in-game cinematics. This allows us to deliver visually rich, interactive experiences with maximum performance and fidelity.
Every step involves close collaboration with the client, ensuring consistency with gameplay and marketing objectives. Yoozoo’s feedback loop has become integral to how we iterate and improve.
A Culture of Collaboration
What makes the Thunder Cloud x Yoozoo collaboration successful isn’t just technical excellence, it’s alignment in values. Thunder Cloud deeply understands the marketing objectives of publishers and brings a collaborative mindset to every phase of production.
With clients across the globe, from North America to Europe and Southeast Asia, Thunder Cloud has built workflows that accommodate time zone differences with ease. While collaboration with Yoozoo is naturally aligned due to regional proximity (China and Singapore), our ability to manage distributed pipelines, fast iterations, and real-time updates extends globally.
Another defining strength is Thunder Cloud’s ability to deliver exceptional execution quality while remaining cost-effective. By reusing and enhancing existing in-game lookdev assets, we help clients save time and budget without compromising artistic quality. This execution efficiency has made Thunder Cloud a go-to partner not just for creative vision, but for production dependability.
Our proactive communication style and streamlined feedback handling have made us more than a service provider. We become creative partners, helping shape narratives that resonate globally. Teams at Yoozoo appreciate not just the visuals we deliver, but also the strategic thinking behind them, which has made repeat collaboration a natural outcome.
From Trailer to Full-Service Support

While Thunder Cloud is best known for its high-end cinematic trailers, many clients begin with a single project and scale into a broader relationship. For Yoozoo and others, this includes user acquisition (UA) videos, lookdev and rigging, real-time scene setup in Unreal Engine, and ongoing content support for live events or seasonal campaigns.
We’ve designed our services to be modular, which means clients can engage us for a short campaign or a long-term integrated content pipeline. This approach fits both AAA publishers looking for flexible production bandwidth, and growing studios aiming to elevate their marketing assets without expanding internal teams.

Elevating IP Through Stylized Storytelling

Thunder Cloud doesn’t just animate characters, we bring entire IPs to life. Our ability to translate narrative arcs and gameplay mechanics into compelling motion visuals is what sets us apart.
