London-based cloud games firm Improbable has said that ambitious projects like those using its SpatialOS tech come with risk.

In a statement to GamesIndustry.biz, the company said that the three titles using SpatialOS which have been cancelled in three consecutive months all were axed due to different problems.

Bossa Studios announced that Worlds Adrift was closing at the end of May, before Cambridge-based Automaton said that its ambitious battle royale title Mavericks: Proving Grounds was being cancelled as the developer was entering administration.

That was before Spilt Milk - who was working in Improbable's London office - revealed that its ambitious MMO Lazarus was being axed just yesterday (Monday, August 12th).

"These are three very different situations - different kinds of games being made by different studios, and with different reasons for closing down," a spokesperson said.

"The one thing we would say about this is that many games do not reach a full launch, and that ambitious, visionary products always contain some risk."

Asked specifically about Lazarus being killed, the Improbable rep continued: "Spilt Milk Studios is a talented studio who started developing with SpatialOS as early adopters. We're sorry to see Lazarus will not get a full release, but we hugely appreciate Spilt Milk's early interest in SpatialOS, and the improvements to the platform that came from their feedback. We'll look forward to seeing their future games."
