Galaxy Attack 獲得超過 5,000 萬次安裝次數，以及超過 500,000 顆五星評等，是廣受歡迎的外星射擊遊戲。越南遊戲開發人員 OneSoft 希望進一步擴大觸及範圍，因此決定採用 Google Play 免安裝技術，安裝率也大幅提高。
具體措施
OneSoft 已在 Play 商店中發布多款成功的遊戲，但這些是 Google Play 免安裝功能的新遊戲。團隊為熱門的太空射擊遊戲 Galaxy Attack 製作了一個精簡版。OneSoft 執行長 Trhangn Mănh Hăng 表示：「我們以原遊戲為基礎，使用者或許會覺得遊戲好玩又容易上手，但玩家還是覺得遊戲簡單。
當使用者瀏覽 Google Play 上的遊戲資訊時，他們只要按一下「立即體驗」按鈕，就能啟動精簡版。
成果
OneSoft 回報，自家安裝次數增加了 15%，而部分市場 (例如德國) 的安裝次數提升了將近 30%。使用者喜歡透過 Google Play 免安裝功能體驗的遊戲過程，讓玩家日後想繼續玩下去。
事實上，OneSoft 發現，相較於直接從 Play 商店資訊頁面下載的使用者，透過「立即體驗」按鈕安裝應用程式的使用者多花了 36% 的遊戲時間。第 1 天和第 7 天的使用者留存率也較高，因為對初次體驗 Google Play 免安裝體驗的使用者而言，續航率也更為出色。
Trjann 說：「我們對於這項卓越的搜尋結果感到非常開心，我們對此感到十分驚喜。」
「Google Play 免安裝是一項很棒的功能，可協助我們吸引真正感興趣的使用者，進而提高留存率和參與時間。」
實驗結果證明，OneSoft 團隊推出另外兩款即時遊戲：Space Shooter: Galaxy Attack 和 Arcade Shooting。團隊甚至還向其他遊戲開發人員提供建議，說明如何推出成功的免安裝遊戲。
