As Gabriel Logan, one of the government's top agents, you must neutralize the terrorists that threaten Washington D.C. and destroy a biological weapon that has been built to end the lives of millions of innocent people. The action unfolds over thirteen missions that are chock full of dangers, hazards and puzzles.
Syphon Filter is based around a covert operation sent in to disarm a lethal virus code of the same name. To successfully complete your mission, you must utilize each of your character's skills accordingly. Logan will have to kneel, crouch, walk, roll, climb, jump and run to meet his objectives. Each one serves a different purpose and it will be up to you whether you should try to jump a laser-alarm or crawl under it.
