Game engine maker Unity Technologies has reversed its excommunication of cloud service provider Improbable with a revision of its Terms of Service that allows game developers to work with unapproved technology providers.

Last week, Improbable, the UK-based maker of the SpatialOS Game Development Kit (GDK) for the Unity game engine, alarmed the community by warning that it had been found to be in breach of Unity's Terms of Service, potentially jeopardizing every project integrating the SpatialOS GDK as a cloud-based backend.
