One user hosts and the other joins a game, battle against your friends in the same Augmented space.

This app is only ~7MB once expanded, there are no additional parts downloaded. This has been achieved, in part, by creating as many 3d models and materials programmatically as possible.
SinkAR creates a peer-to-peer network with devices around you, utilising RealityKit's Collaborative AR Sessions.
