Tactical Fleet Simulator (TFS) is a total overhaul with the aim of transforming Homeworld2 into a tactics-oriented strategy game. Initial versions aimed for a more immersive tactical "simulator" orientation, the current version provides a more refined and consistent RTS experience.
For when I can't be bothered playing a complex game, TFS delivers great gameplay with many new ship designs but still retaining the original HW2 aesthetic (just with many many more guns!)
