Unity LevelPlay is an ad mediation and monetization platform which lets developers manage multiple advertising networks through a single SDK. It supports real-time bidding and waterfall mediation, allowing ad networks to compete for impressions, while providing reporting, A/B testing and tools for optimizing ad revenue and the player experience.

The former ironSource extension has been replaced by the Unity LevelPlay extension, reflecting Unity’s current SDK, branding and API. LevelPlay itself is the successor to ironSource’s mediation platform and continues to support multiple advertising networks on Android and iOS. Unity is retiring the separate ironSource Ads direct-demand network.

What’s new in 2.0.0?

  • Migrated from the legacy ironSource API to Unity LevelPlay SDK 9

  • New object-based Lua API for rewarded, interstitial and banner ads

  • Explicit creation, loading and displaying of individual ad units

  • Support for multiple ad objects and ad-unit IDs

  • Updated Android and iOS mediation SDKs and adapters

  • Updated extension configuration under the new [levelplay] section

  • Updated example project, documentation and API reference

  • Renamed the extension and Lua namespace from ironsource to levelplay

  • Improved dependency generation and validation for supported mediation networks

The extension supports Unity LevelPlay mediation on both Android and iOS, with configurable adapters for networks such as Unity Ads, Google AdMob, AppLovin, Meta Audience Network, Pangle, Mintegral and others.
