Unity developers can now make ambitious multiplayer games via Improbable's SpatialOS tech.

The London-based cloud-tech company announced today that it was rolling out the GDK for its fancy technology, having entered a pre-alpha stage in June of this year.

Furthermore, the firm has also thrown in a sample game simply called 'FPS Starter Project', which allows 200 players to compete. So we can expect a number of battle royale projects to come out of indie game jams in the near future.

This also increases the likelihood of more mobile games using SpatialOS. Though Unreal Engine 4 does support smartphones, it's hardly a focus on Unity. 

SpatialOS also supports Unreal Engine 4 as well as CryEngine.
