How to unlock the Ground Sweeper achievement in Novastrike - Definitive Guide
Like the 'Destroyer' trophy, this should be accomplished before finishing the game. Just make sure to hit all turrets, bases etc. while playing through because it'll make things easier anyway. You cannot start a new game or change difficulties while going for this achievement.
