Not much info about the game yet. It's going to use the Unreal engine. The
Facebook group has the usual Tribes dissent over which flavor of the game
the new version should be modeled after. A few voices of reason recognize
the need for a high degree of modding so that it can be adapted to keep
each faction happy.
