背景
Spokko 位於波蘭，匯集了一群雄心壯志的創作者，致力為 IP 位址極為嚴苛。雖然 Spokko 是 CD PROJEKT 家族的一員，但這家獨立公司已將《巫師：怪物大逃殺》的精彩世界轉移到智慧型手機。
《獵魔士：怪物殺手》是一款以地點為基礎的角色扮演遊戲，運用擴增實境技術。這是一款需要大量運算能力的遊戲，對許多裝置都相當挑戰。遊戲發布時，Spokko 想確保自家遊戲觸及最多使用者，同時為所有人提供優質體驗。
具體措施
《獵魔士：怪物戰士》在紐西蘭先進行三階段試行，並陸續新增多個國家/地區。該公司從技術階段開始著手，目的是檢查裝置相容性並檢查技術問題。第二階段的重點在於留存率，進一步瞭解使用者是否喜歡遊戲，以及如何延長工作階段持續時間。第三階段著重營利，以及玩家是否願意付費購買額外的遊戲內商品，以及感興趣的商品。他們也收集到大量遊戲資料，從而盡可能針對更多裝置進行遊戲最佳化，同時改善新舊 Android 裝置上的遊戲平衡。
在初始技術階段，Spokko 使用 Android Performance Tuner，根據軟體階段啟動期間的實際使用情形，評估不同裝置上的遊戲效能。此外，他們還透過 Play 管理中心和裝置目錄陸續加入更多裝置。透過這項資訊，他們得以關閉效能低落的裝置，安心地在各式各樣的裝置上推出應用程式。「APT 能夠幫助我們瞭解個別裝置的技術能力，以及裝置的效能。同時，我們也能夠根據效能最差的硬體相關問題，取得相關統計資料。APT 幫助我們調查哪款智慧型手機可提供最佳效能。」
成果
最初開發團隊時，僅限正式支援 ARCore 的裝置。透過 Android Performance Tuner，他們可以全面瞭解執行 The Witcher: Monster Slayer 的所有硬體。最終，他們加入許多不支援 ARCore 的裝置，在短短兩週內就從 520 部裝置擴充至 9280 部裝置，使下載量成長了 10%。
身為執行製作人 Mateusz Janczewski 所言，「我們起初計劃在搭載 ARCore 的裝置上提供 Monster Slayer，因為這樣可大幅限制玩家可下載遊戲的裝置數量。然而，根據玩家的看法，我們鼓勵我們尋找其他解決方案，以進一步拓展服務範圍。我們提議使用「裝置」目錄和 Android Performance Tuner 來達成這個特定用途。如果沒有這些技術，我們便無法滿足玩家的要求，也無法在極短的時間內增加與遊戲相容的裝置數量。」
日後，Spokko 計劃新增更多品質等級的其他遙測資料，以決定哪些裝置應以正常品質或高畫質玩遊戲。他們也計劃在遊戲的不同區塊加入遙測資料，進一步瞭解不同部分的效能，像是在地圖上、戰鬥中或場景拍攝期間的表現。

Although it is part of the CD PROJEKT family, Spokko is an independent company that has transferred the great world of [The Witcher: Monster Slayer](https://play.google.com/store/apps/details?id=com.spokko.witchermonsterslayer) to smartphones.\n\nThe Witcher: Monster Slayer is a location-based RPG game that uses augmented-reality technology. It's a computationally intensive game that would challenge many devices. At launch, Spokko wanted to ensure their game would reach the largest number of users, while providing a high quality experience for everyone.\n\nWhat they did\n-------------\n\nThe Witcher: Monster Slayer started with a three-phase soft launch in New Zealand, and added several additional countries over time. They started with the technical phase, to check the compatibility of devices and examine technical issues. The second phase focused on retention, to better understand whether users like the game and how to increase their session duration. The third phase focused on monetization, and whether players would be willing to pay for additional in-game items, and what items they were interested in. They also collected a lot of gameplay data, which allowed them to optimize the game for as many devices as possible, and to improve the gameplay balance on both newer and older Android devices.\n\nDuring the initial technical phase, Spokko used [Android Performance Tuner](https://developer.android.com/games/sdk/performance-tuner) to assess the game's performance on different devices based on actual usage during the soft-launch. They also used [Play Developer Console](https://play.google.com/console/about/) and [Device catalog](https://play.google.com/console/about/devicecatalog/) to add additional devices over time. With this information, they were able to turn off under-performing devices and confidently launch on a wider variety of devices. \"APT allowed us, above all, to get acquainted with the technical capabilities of individual devices and what their performance was like. We were also able to get statistics using information about issues in the area of the worst-performing hardware. APT allowed us to investigate which exact smartphones give us the best performance,\" said Kacper Bąk, Lead of Business Intelligence.\n\nResults\n-------\n\nInitially, the team only enabled devices that officially supported ARCore. By using Android Performance Tuner, they gained a comprehensive overview of the hardware on which The Witcher: Monster Slayer was running. Eventually, they added many devices that did not support ARCore, expanding from 520 devices to 9280 devices in only two weeks, which led to a 10% increase in downloads.\n\nAs Mateusz Janczewski, Executive Producer, puts it, \"Initially, we planned to make Monster Slayer available on devices with ARCore, which significantly limited the number of devices players could download the game on. However, the opinions of players encouraged us to look for additional solutions that would extend the availability. We came up with the idea to use the Device catalog, along with the Android Performance Tuner, for this particular purpose. Without these technologies, we would not meet the requests of players, and we would not be able to increase the number of devices compatible with the game in such an extremely short time.\"\n\nIn the future, Spokko plans to add additional telemetry around quality levels to decide which devices should play the game with normal quality or high quality. They also plan to add telemetry to different sections of the game, to better understand how different parts perform, such as on the map, within combat, or during cutscenes.\n\nGet started\n-----------\n\nGet started today by learning more about [Android Performance Tuner](https://developer.android.com/games/sdk/performance-tuner) and discover how you can increase your game's reach, while ensuring that all your players have a high quality experience."]]
