Unity Free Leaderboard - Using AWS DynamoDB Integration

Unity Free Leaderboard High score table

Imagine empowering your game with a truly global, real-time leaderboard – without spinning up any servers or wrestling with custom back-ends. With AWSGameStatePersistor, you can:

• Tap into AWS’s generous free tier: get 25 GB of storage for life and up to 20 million DynamoDB API calls per month at no cost.

• Integrate in minutes: simply add the provided AwsGameStatePersistor.cs script to your Unity project, enter your Access Key, Secret Key, table name, and region – no additional dependencies, no boilerplate.

• Render beautiful leaderboards: couple it with the sample HighScoreTable.cs script and a Canvas UI component, then configure “Game Item Key,” “Sort Numeric Values,” and “Max Items To Fetch” to display your top N scores instantly.

Beyond high scores, AWSGameStatePersistor lets you store any global game state – player progress, unlockable content, cross-session settings, and more. Each “game item key” is a separate namespace, so you can maintain multiple leaderboards or state blobs in the same DynamoDB table. And if you need to avoid collisions between players who share the same name, the Unique Items Per Computer flag ensures each device writes its own distinct entry.

Built on DynamoDB’s rock-solid, low-latency NoSQL engine, you benefit from AWS’s automatic scaling, high availability, and regional redundancy – all managed for you. With up to 440 KB per item (roughly 8,000–10,000 leaderboard entries per key), you won’t outgrow your table anytime soon, and you only pay when you exceed the free limits.

Ready to level up your game’s engagement? Follow the step-by-step guide in the manual to create your DynamoDB table, configure IAM credentials, and add AWSGameStatePersistor to your Unity scene. Your players will love seeing their names climb the world rankings, and you’ll love how simple it is to maintain a global game state – all backed by AWS’s free tier and industry-leading infrastructure.
