Mercenary Games has been developing a strategy game called Vigrior : Maneuver Warfare. The team has been operating through underground channels, and even behind corporate walls. Their team leader is a former US Marine artilleryman, and he has incorporated military doctrine into the core game mechanics.
The game focuses on maneuver warfare and battle formations. Players control Fleets, and are able to execute complex battle maneuvers with one mouse click.
This project has had a colorful history. For a first look into it, follow this link.
