How do you play the game on the harder settings? What works and what tends to fail in your experience? Personally... Approaching a group of enemies equipped with a Magnum and SMG I start with taking out all of the grunts while remaining behind cover trying to avoid the larger enemies. Then I work my way around the larger enemies making it to where I can 1vs1 them with weapons... or if I decide to use grenades I'll try to drive them closer to each other. However the way I'm playing seems rather campy and I feel as if there may be a faster and more effective way in approaching a situation that I may simply not be realizing. So basically... what are weaknesses of the enemies and how do we exploit them in the most effective way in your opinion?
