So much goes into building and maintaining a mobile game. Let's say you want to ship it with a level builder for sharing content with other players and, looking forward, you want to roll out new content and unlockables linked with player behavior. Of course, you also need players to be able to easily sign into your soon-to-be hit game.

With a DIY approach, you'd be faced with having to build user management, data storage, server side logic, and more. This will take a lot of your time, and importantly, it would take critical resources away from what you really want to do: build that amazing new mobile game!

Our Firebase SDKs for Unity and C++ provide you with the tools you need to add these features and more to your game with ease. Plus, to help you better understand how Firebase can help you build your next chart-topper, we've built a sample game in Unity: MechaHamster. Check it out on Google Play or download the sample project at Github to see how easy it is to integrate Firebase into your game.

Before you dive into the sample code for MechaHamster, here's a rundown of the Firebase products that can help your game be successful.

Firebase Products for Games

Analytics

One of the best tools you have to maintain a high-performing game is your analytics. With Google Analytics for Firebase, you can see where your players might be struggling and make adjustments as needed. Analytics also integrates with Adwords and other major ad networks to maximize your campaign performance. If you monetize your game using AdMob, you can link your two accounts and see the lifetime value (LTV) of your players, from in-game purchases and AdMob, right from your Analytics console. And with Streamview, you can see how players are interacting with your game in realtime.

Test Lab for Android

Before releasing updates to your game, you'll want to make sure it works correctly. However, manual testing can be time consuming when faced with a large variety of target devices. To help solve this, we recently launched Firebase Test Lab for Android Game Loop Test at Google I/O. If you add a demo mode to your game, Test Lab will automatically verify your game is working on a wide range of devices. You can read more in our deep dive blog post here.

Authentication

Another thing you'll want to be sure to take care of before launch is easy sign-in, so your users can start playing as quickly as possible. Firebase Authentication can help by handling all sign-in and authentication, from simple email + password logins to support for common identity providers like Google, Facebook, Twitter, and Github. Just announced recently at I/O, Firebase also now supports phone number authentication. And Firebase Authentication shares state cross-device, so your users can pick up where they left off, no matter what platforms they're using.

Remote Config

As more players start using your game, you realize that there are few spots that are frustrating for your audience. You may even see churn rates start to rise, so you decide that you need to push some adjustments. With Firebase Remote Config, you can change values in the console and push them out to players. Some players having trouble navigating levels? You can adjust the difficulty and update remotely. Remote Config can even benefit your development cycle; team members can tweak and test parameters without having to make new builds.

Realtime Database

Now that you have a robust player community, you're probably starting to see a bunch of great player-built levels. With Firebase Realtime Database, you can store player data and sync it in real-time, meaning that the level builder you've built can store and share data easily with other players. You don't need your own server and it's optimized for offline use. Plus, Realtime Database integrates with Firebase Auth for secure access to user specific data.

A few months go by and your game is thriving, with high engagement and an active community. You're ready to release your next wave of new content, but how can you efficiently get the word out to your users? Firebase Cloud Messaging lets you target messages to player segments, without any coding required. And Firebase Dynamic Links allow your users to share this new content — or an invitation to your game — with other players. Dynamic Links survive the app install process, so a new player can install your app and then dive right into the piece of content that was shared with him or her.

Build great games

At Firebase, our mission is to help mobile developers build better apps and grow successful businesses. When it comes to games, that means taking care of the boring stuff, so you can focus on what matters — making a great game. Our mobile SDKs for C++ and Unity are available now at firebase.google.com/games and don't forget to check out our sample game project, MechaHamster, on GitHub.
