The game has flaws; a few bugs in the abilities (I use the ability to be invisible and the enemies still fill me with lead). BUT, the story is akin to a true spy film, with twist and turns everywhere, and reprecussions for almost everything you do (do you kill this guy and lose information that can make another mission easier or do you let him go and risk the lives of millions, believe it or not that is actually one of the options). The combat is not the best nor is it it the worst, with an assortment of abilities, Close Quarter Combat and weapons, the game gives no restraint on options; you want to blow things up go ahead or you want to move like a shadow in the night, knock yourself out. It is an action rpg that though flawed is by far not the worst choice on the market; good story, characters, settings and combat make up for some of the buggy gameplay (nowhere as bad as Fallout).
