In addition to releasing original franchises\nlike Asphalt and Dungeon Hunter, Gameloft partners with major\nentertainment studios like Disney, LEGO, and Universal\nIllumination to build games for their most popular brands.\n\n*** ** * ** ***\n\nChallenge With such a broad portfolio and global audience, having the\nability to monitor the stability of games in a holistic way is\ncritical to Gameloft's success. Therefore, they needed a robust\ncrash reporting tool to track and troubleshoot issues across all\nof their games. \"We were lacking proper information about crashes,\nespecially native crashes from our players,\" said Oana Radulescu,\nDeployment Operations Manager at Gameloft. Crash events were\ndifficult to reproduce, and unforeseen technical issues were hard\nto track down and fix before they affected a large number of\nplayers. \n\n*** ** * ** ***\n\nSolution \nThat's when Gameloft turned to [Firebase Crashlytics](/products/crashlytics).\nBy aggregating crashes by root cause and highlighting the\nimpact on players, Crashlytics helps Gameloft see what to fix\nfirst --- especially useful given the large number of games they\nmanage. \"Crashlytics makes it easy to analyze stack traces,\nhelps us prioritize issues, and provides vital information for\neach bug,\" Radulescu said. \"We instrumented logs and keys to\nget details and context surrounding crashes --- like the\naffected track or car in a racing game --- so we can reproduce\nand resolve them faster than ever.\" \nWhen one of their games, Overdrive City, was suffering from\nmysterious crashes, the team received a [velocity alert](/docs/crashlytics/velocity-alerts),\nwarning them that the issue had increased in severity. Thanks\nto the alert, the Gameloft team swiftly took action and found\nthe culprit --- a malfunctioning ad module --- and temporarily\ndeactivated it while they fixed the problem, reducing the\npercentage of users experiencing crashes by 10% overnight.\nPlayers appreciated the quick fix. According to Gameloft, in\nthe subsequent weeks, crashes remained low, the game's Play\nStore rating went up, and session duration increased by 16%,\nfrom 6 minutes to 7 minutes. Since then, Crashlytics has\nbecome an integral part of Gameloft's ability to monitor\nstability, roll out features with confidence, and keep\nplayers happy.\n\n*** ** * ** ***\n\nResults\n\n16% increase in session duration\n\n10% reduction in percentage of users experiencing crashes \n\n\"We went from blindly trying to fix issues from vague user comments and incomplete stack traces to getting all the information we need to improve stability. Now we spend less energy on troubleshooting bugs and more time building amazing gaming experiences.\"\n\n\n- Oana Radulescu, Deployment Operations Manager, Gameloft \nTry Firebase today\n\n\nIntegrating it into your app is easy.\n[Get started](https://console.firebase.google.com/) \n\nAll Firebase products \n\nBuild\n\n- [App Check](/products/app-check)\n- [App Hosting](/products/app-hosting)\n- [Authentication](/products/auth)\n- [Cloud Functions](/products/functions)\n- [Cloud Storage](/products/storage)\n- [Data Connect](/products/data-connect)\n- [Extensions](/products/extensions)\n- [Firestore](/products/firestore)\n- [Firebase ML](/products/ml)\n- [Genkit](https://genkit.dev/)\n- [Hosting](/products/hosting)\n- [Realtime Database](/products/realtime-database)\n- [Firebase AI Logic client SDKs](/products/firebase-ai-logic)\n\n[Generative AI](/products/generative-ai) \n\nRun\n\n- [A/B Testing](/products/ab-testing)\n- [App Distribution](/products/app-distribution)\n- [Cloud Messaging](/products/cloud-messaging)\n- [Crashlytics](/products/crashlytics)\n- [Google Analytics](/products/analytics)\n- [In-App Messaging](/products/in-app-messaging)\n- [Performance Monitoring](/products/performance)\n- [Remote Config](/products/remote-config)\n- [Test Lab](/products/test-lab)"]]
