Improbable and Epic Games have announced a surprise new $25,000,000 fund "to help developers transition to more open engines, services, and ecosystems". The announcement comes just hours after a public war of words between Improbable and Unity, after the former claimed that a recent change in Unity's terms of service rendered its SpatialOS technology in breach of Unity's terms – and thus potentially fatal to SpatialOS / Unity titles including Lazarus and Worlds Adrift.

Unity made the counter-claim that Improbable had been advised well in advance of the December Terms of Services change, and that anyway, games using SpatialOS – including Lazarus and Worlds Adrift – would not be affected by the deactivation of Improbable's Unity Editor license keys. Andy has the blow-by-blow here. It appeared as if the companies were close to a resolution, but the newly revealed Epic / Improbable initiative paints another picture.
