I played(and completed)this game on PS2 before,and I can say that this is an amazing game ^_^
I remember how this game just captivated me when I first played it on PS2,because of the amazing music,characters,etc in it
The plot(in a summary): The President of Georgia is assasinated,allowing billionaire Kombayn Nikoladze(main antagonist)to seize power by bloodless coup d'etat. Sam FIsher(the character you play as),former Navy SEAL officer and Persian Gulf War,is recruited by the NSA to work with it's new division,Third Echelon. He is dispatched to Tbilisi to investigate the disappearence of 2 CIA officers. He finds out that a man named Vyacheslav Grinko(another antagonist)removed their subdermal tracking devices and tracks him down to the defense ministry,finding out that Nikoladze is doing an illegal operation in Azerbaijan. Sam goes to an oil rig and finds that NATO forces are sending fighter jets to bomb the rig,he finds Piotr Lejava and gets his suitcase,which has a laptop containing an encryption key to"The Ark". The information is revealed to have come from a mole in the CIA,so Sam goes to the CIA HQ to investigate,and interrogates Mitchell Dougherty,finding that his OCD caused him to backup data on an insecure laptop,which was exploited by a network owned by Kalinatek. He goes to Kalinatek and finds Ivan,and gets his encryption key. He goes to the Chinese Embassy in Myanmar and finds that the Chinese general Feirong is working with Nikoladze,and that American soldiers are going to be executed on live TV. He rescues the soldiers,and kills Grinko in a firefight. He goes back to the Chinese Embassy and forces Feirong to shre information stored on his computer,which reveals that Nikoladze fled back to Georgia. Sam goes back to Georgia and finds Nikoladze in the Presidential Palace,where he narrowly escapes being killed,with Lambert's arranged blackout saving him. He then assassinates Nikoladze after learning that he is disclosing The Ark's location.
The music is amazing.
The characters are amazing,especially Lambert and Grimsdottir.
The stealth mechanics are pretty good too(even if the AI can be wonky at times)
Anyways,overall this is an amazing game that I recommend to everyone.
10/10 from me ^_^
