That's when Gameloft turned to Firebase Crashlytics. By aggregating crashes by root cause and highlighting the impact on players, Crashlytics helps Gameloft see what to fix first — especially useful given the large number of games they manage. "Crashlytics makes it easy to analyze stack traces, helps us prioritize issues, and provides vital information for each bug," Radulescu said. "We instrumented logs and keys to get details and context surrounding crashes — like the affected track or car in a racing game — so we can reproduce and resolve them faster than ever."

When one of their games, Overdrive City, was suffering from mysterious crashes, the team received a velocity alert, warning them that the issue had increased in severity. Thanks to the alert, the Gameloft team swiftly took action and found the culprit — a malfunctioning ad module — and temporarily deactivated it while they fixed the problem, reducing the percentage of users experiencing crashes by 10% overnight. Players appreciated the quick fix. According to Gameloft, in the subsequent weeks, crashes remained low, the game's Play Store rating went up, and session duration increased by 16%, from 6 minutes to 7 minutes. Since then, Crashlytics has become an integral part of Gameloft's ability to monitor stability, roll out features with confidence, and keep players happy.
