Compared with anime-style, open-world, party, shooter and other segments backed by major studios with high exposure and heated discussion, most Chinese SLG companies that have long been rooted overseas remain mid-sized and rarely stand in the spotlight. Yet they often have stable product methodologies, mature user acquisition and long-term operation capabilities, and have already accumulated considerable commercial results in the global market.

Leyi Network is a fairly typical example. Since its founding, the company has focused on the SLG track, with titles such as West Game, Blaze of Battle, Marsaction: Infinite Ambition, and Mad Survivor: Arid Warfire, covering themes including Western European fantasy, cowboys, Mars mecha, post-apocalyptic wastelands and modern zombies.

However, although the above products delivered strong performances at different stages, the company’s core hit has remained West Game, launched in 2019. Since launch, the title has operated steadily over the long term and is one of the few representative Western-themed SLG successes from Chinese developers. Its average monthly revenue was still around $2.5 million in 2024 (about RMB 17 million), slipped slightly to around $1.6 million in 2025 (about RMB 11 million), and has fluctuated between $1 million and $800,000 per month this year.

Of course, Leyi also understands that even evergreen titles are constrained by product cycles, and that continuously searching for new “cash flow” is the way to survive. As a result, its pace of testing and iterating new products has remained active over the past two years.

Recently, DianDian Global found that Leyi’s new post-apocalyptic zombie SLG, Kingdom Fall: Zombie Defense (hereinafter Kingdom Fall), has begun its first overseas scale test. Within two weeks, daily revenue grew from three digits to nearly $15,000 (about RMB 100,000).

What kind of product is this? What does its overall testing cadence and market data look like? Could it be Leyi’s next major bet? What product-side breakthroughs has Leyi made over the past two years? Below, DianDian Global will break down and analyze these questions in detail.

Differentiating Through “Thronefall + Sky Shelter”

Kingdom Fall’s First Scale Test Reaches 530K Downloads in 15 Days

Kingdom Fall has an art style similar to 37 Interactive Entertainment’s Last Asylum. Although it uses the relatively common post-apocalyptic zombie theme, it sets the backstory in the medieval era: a kingdom that had stood for centuries collapses within weeks due to a mysterious plague; the dead become mindless monsters that devour everything in their path, while castles and villages are reduced to ruins. As a lord, the player must lead survivors to rebuild their homeland, recruit heroes and resist the undead army.

Unlike other post-apocalyptic titles that place city building on the ground, this game shifts it to a wooden shelter suspended high above the ground. In official screenshots, survivors live in an elevated area made up of wooden bridges, platforms, towers, tents and firelight, while dark forests and encroaching zombie hordes lie below. This clear vertical spatial layering makes attacks feel more oppressive, differentiates the game from similar products on the market, and also benefits ad creative production.

The underlying gameplay framework is “Thronefall + sky-shelter management + 5v5 card battles + SLG,” with an overall transition logic quite similar to Kingshot. In the early game, users are mainly attracted by shelter construction and Thronefall-style tower defense, two content modules that can quickly provide validation and feedback.

Retention then depends more on simulation management. Inside the shelter, players handle arriving survivors, logging, cooking, beds, building upgrades and staff allocation. After surviving a wave of crisis, players return to base to manage resource production and living facilities, then unlock new areas and buildings. At this point, the game begins to approach the SLG/simulation strategy framework that Leyi excels at: using building levels, resource requirements, population capacity and staged tasks to create continuous goals, allowing players to see the base grow from a small refuge into a complete town.

At the same time, 5v5 card battles are introduced, with hero recruitment, lineup building, equipment and upgrades forming a progression line tied to long-term operation and monetization. Once players pass the early survival and development phase, larger-scale SLG content such as the world map and alliance warfare comes into play.

According to DianDian Data, Kingdom Fall was first listed on Google Play in most countries and regions in late May 2026, and on the App Store in early June. The launch timing on both platforms also corresponds to when user acquisition began. The game is now available in nearly 170 regional markets worldwide.

Looking at specific market performance, the game officially began testing on May 30 and started generating trackable data.

In terms of downloads, because the game adopted a concentrated burst UA strategy with limited creatives, downloads reached 12,000 on the first test day and then continued to grow. After a small replenishment of ad spend on June 4, daily downloads peaked at 56,000 the following day, before gradually declining. Current daily downloads are around 30,000.

On the revenue side, although first-day revenue was less than $500, it then began to rise steadily. Current daily revenue is around $13,400 (about RMB 91,000).

As of now, Kingdom Fall has been in testing for 15 days. Although this is its first scale test, the overall scale has been relatively restrained: after deduplication, there are 676 ad creatives on Android and 305 on iOS. In terms of market coverage, key target countries include the United States, Italy, Brazil, Singapore and Senegal, reflecting a broad T1 + T2 + T3 rollout strategy.

Against this UA backdrop, the game has accumulated approximately 533,000 downloads. The United States, Brazil and Thailand rank as the top three markets with shares of 11.22%, 9.84% and 6.44%, respectively. By platform, Google Play contributes the larger share at around 78.08%.

Total revenue is estimated at around $114,000 (about RMB 770,000). The United States, Germany and France are the top three revenue contributors, with shares of 26.24%, 11.91% and 5.94%, respectively. By platform contribution, Google Play takes a dominant 78.66%. In terms of RPD (revenue per download), the figure is around $0.21 (about RMB 1.44).

Combining the gameplay with the market data from its first scale test, Kingdom Fall builds a certain level of differentiation by adding a sky-shelter concept to an already validated mature framework. The transition from early to mid-game is relatively smooth, and the product is highly complete, giving it its own competitiveness in the current market. The UA strategy and scale of the first test also suggest that Leyi attaches considerable importance to the title. If the data meets expectations, subsequent tests should not be far away.

It is also worth noting that, in addition to Kingdom Fall, Leyi currently has other new SLG titles in testing, including Frozen Island and Virox: Global Outbreak. Virox began testing in March this year, once peaked at more than 50,000 daily downloads, and reached $343,000 in April revenue (about RMB 2.32 million). However, as UA tightened in mid-to-late April, its data also declined. Current daily downloads fluctuate around 3,000, while daily revenue is around $7,000.

Leyi’s Two New Games Bloomed in 2025

Mecha Fire and West Game II Grossed Over $12.65M Combined

In fact, compared with this year’s new-game pipeline, Leyi’s 2025 was the more fruitful year, as it successively launched two high-profile titles globally: Mecha Fire and West Game II.

Mecha Fire is a light sci-fi alien-world SLG set in a new era of interstellar colonization, where humans must survive illness in the harsh Martian environment, fight insect swarms and build a home. Its underlying framework is “simulation management + SLG,” similar to WOS. The early core is to resolve survival pressure, mainly through base building and receiving and assigning refugees. Combat uses real-time card battles in a squad-based mowing format, while progression involves not only improving hero power but also developing mecha troops.

Although the game was first listed in October 2024, it did not generate trackable market data until mid-January 2025. In March of the same year, as UA scale expanded, its data began to rise sharply, reaching 680,000 monthly downloads and $402,000 in monthly revenue (about RMB 2.9 million).

After that, downloads peaked at 815,000 in April, then began a gradual decline. By the end of 2025, monthly downloads had fallen below 500,000 (with total 2025 downloads of around 5.1 million). Downloads rose again to 756,000 in January this year, but soon dropped sharply once more. Current monthly downloads are around 80,000.

Unlike the “twists and turns” on the download side, monthly revenue continued growing until October 2025, when it peaked at $1.24 million (about RMB 8.5 million), before entering a fluctuating decline. Current monthly revenue is around $510,000 (about RMB 3.44 million).

Mecha Fire Monthly Revenue Trend Since Test Launch

Since testing began, the title has generated total revenue of $13.14 million (about RMB 89.1 million). The United States, Germany and the United Kingdom rank as the top three revenue markets with shares of 45.14%, 5.72% and 4.6%, respectively. Cumulative downloads are around 6.5 million, with the United States, Brazil and France contributing the top three shares at 19.97%, 11.93% and 4.05%.

The latter, the Western-themed SLG West Game II, is clearly an IP sequel to Leyi’s core product West Game. In terms of gameplay, the early game uses Thronefall-like elements to attract users, introducing construction and production, then unlocking card-based stage progression and hero development, followed by world-map access and the addition of traditional SLG content.

The title was first listed in some countries and regions in July 2025 and gradually began official testing globally on September 21. The next day, it entered the iOS free games TOP 50 in 115 regional markets. First-month downloads reached 1.17 million, while revenue reached $403,000 (about RMB 2.73 million).

After that, downloads fluctuated upward through January 2026, with monthly downloads staying above 1.58 million. A clear decline began only in February this year, and current monthly downloads are around 520,000.

West Game II Monthly Download Trend Since Test Launch

The revenue trend largely mirrors the download trend. Monthly revenue rose steadily, first crossing the million-dollar mark in November 2025 ($1.3 million, about RMB 10.63 million), then reaching a peak of $2.2 million in January this year (about RMB 15 million). Although revenue began to decline in February, the pace has been slow, and current monthly revenue remains stable at around $1 million (about RMB 10 million).

West Game II Monthly Revenue Trend Since Test Launch

As of now, West Game II has been live for nine months, with cumulative downloads of approximately 10.11 million (4.95 million in 2025). The United States, Brazil and Egypt rank as the top three download markets with shares of 16.52%, 8.96% and 5.47%, respectively. Total revenue is estimated at around $12.7 million (about RMB 85.83 million), with the United States, Germany and the United Kingdom contributing the top three revenue shares at 38.74%, 10.36% and 4.87%.

Leyi Enters a New Product Landscape in 2026

Although West Game II Has Taken the Throne, New Potential Hits Are Still Needed

A horizontal comparison shows that Mecha Fire and West Game II generated annual revenue of $9.12 million (about RMB 61.72 million) and $3.53 million (about RMB 23.9 million) in 2025, ranking second and third in Leyi’s revenue last year. This was mainly because both games launched relatively late and did not run for a full year, so their annual revenue was lower than West Game’s $19.2 million (about RMB 130 million).

This year, the company’s new product landscape has become increasingly clear. Mecha Fire clearly lacks the ability to become a long-term hit, allowing West Game II to overtake it. With 2026 revenue of $9.2 million so far (about RMB 62.04 million), West Game II has become Leyi’s highest-grossing product this year. West Game follows closely, but its revenue is only 52.2% of the sequel’s and its overall trend continues downward.

Clearly, after an intense wave of new-game competition, Leyi has for now identified a new pillar product. However, in absolute terms, West Game II’s current revenue still lags noticeably behind West Game at the same stage, so the search for and expansion of potential new titles will continue. Looking at this year, the aforementioned Kingdom Fall and Virox: Global Outbreak are both key products worth continued attention.
