Unity partners with Snap to extend the reach of Unity's ads and integrate SnapKit in Unity's game engine, including Bitmoji in 2021
Context & Ripple Effects
Snap has been building toward this for two years: it opened its identity layer to third-party apps with Snap Kit in 2018, then shipped a Bitmoji For Games SDK letting select developers swap in 3D Bitmoji character skins. The new Unity deal is that strategy hitting scale — instead of courting game studios one by one, Snap gets its avatars and login distributed through the engine itself.
For Unity, this extends a playbook it already ran with Google's AdMob integration in 2018: bundle advertising and now social identity directly into the engine so developers adopt both by default rather than wiring up separate SDKs.
First-order effects
- Unity developers gain in-engine access to SnapKit and, from 2021, Bitmoji avatars as drop-in character skins, removing the per-game integration work the original Bitmoji For Games SDK required.
- Unity Ads extends its reach into Snap's audience network, giving advertisers buying through Unity more inventory and giving Snap a new monetization channel beyond its own app.
Second-order effects
- Other ad networks competing for Unity's developer base face an engine-level rival: when ads and identity ship inside the engine, standalone SDK pitches lose their default position, echoing how AdMob's Unity integration reshaped the field in 2018.
- Snap's avatar business gets a distribution shortcut — every Unity-built mobile game becomes a potential Bitmoji surface, multiplying the avatar's presence without Snap signing individual studios.
Third-order effects
- If engine-embedded ads and identity become the norm, the game engine consolidates into the default integration layer between social platforms and mobile developers, shifting bargaining power toward whoever owns the build tool.
- Avatars functioning as portable cross-game identity points toward social platforms treating character skins as a distribution asset — a pattern Snap started with Snap Kit and is now scaling through a single engine partner.
The trend: Game engines are absorbing advertising networks and social-platform identities as built-in services, turning the engine itself into the distribution layer between platforms like Snap and mobile developers.
