The Syphon Filter series are the kind of games that are great fun to play and excellently programmed, yet somehow the wide publicity and acclaim they deserve escapes them. The Syphon Filter story is an exciting story about two agents in the agency (an undercover US government organisation) who stumble across a dastardly scheme to create a genetically programmable virus which could possibly wipe out most of the population of Earth. The story is full of adventure, bravery, betrayal, and most importantly, top quality action.
This particular game is just the starting point to this story, an introduction to the series, which currently spans three games.
