this is now my second playthrough of clear sky, i tried the playthrough on the hardest difficulty just to see how much of a true stalker i am. its definitely going to remain as my favorite game in the stalker series. the last 2 hours of this game is AWESOME. fighting hordes of monolith in the abandoned hospital with a helicopter boss fight has gotta be one of my favorite moments in the whole series. i absolutely adore the faction system in this game. taking over bases with your favorite faction is so fun and rewarding, if im in the area and my boys call me over to help them defend the base from some mutants or bandits you know my ass will be there asap !!
