Mavericks: Proving Grounds will never get to prove itself, with the game cancelled in the aftermath of its UK-based developer Automaton Games going out of business.
The game was meant to show off the abilities and power of the new cloud tech called SpatialOS, which was meant to see the game running on multiple dedicated servers, all at once. But nope, we won't see that now -- nor will we see the larger 1000-player MMO shooter 'Project X' in a single world. Gone.
The official Automaton Games website has a post, which reads:
Paul Cooper and Paul Appleton were appointed joint administrators of Automaton Games Limited on 30th July 2019. They are managing the affairs, business and property of the company. The joint administrators act as agents of the company and act without personal liability. Please be advised that due to insufficient funding, the development of the Mavericks: Proving Grounds game has now ceased. The joint administrators are in the process of licensing the Deceit game so there will be no change in the live operation and provision of this game.
