The future of several MMOs using SpatialOS cloud server tech is in question over a dispute between Unity Technologies and SpatialOS studio Improbable. The dispute is over a change in Unity’s terms of services in December. Improbable released a statement saying that Unity have now revoked their Unity development license. So far, Spilt Milk’s early access space shooter MMO Lazarus briefly went offline, but is tentatively up and running for the time being. Bossa’s steampunk ship-builder Worlds Adrift will continue as normal for the moment.
