After the release of Metal Gear Solid in March 1999, the stealth-action title, Syphon Filter was released and promoted. At first it was known as the poor-man's Metal Gear Solid, but as short time passed Syphon Filter lived up to its own name, and was selling well all over the world. This game combined the stealth concepts of MGS and the third-person adventure style like Tomb Raider and combined them into a completely new and thrilling must-have game.

It is obviously recommend you should refrain from playing Syphon Filter 2, 3, The Omega Strain or Dark Mirror, until you've finished the first.

Covert Operative Gabriel Logan and his Expert Commmunications Partner Lian Xing are investigating the location of a laboratory of what they and their Agency suspected was involved in creating a powerful next-generation biological virus, called Syphon Filter. During the operation, another lone American special agent Ellis is executed nearby after being held captive, captured carrying out the same operation. Nearby his dead body, the laboratory they were searching for suddenly erupts in flames. They could not recover evidence among the scorched remains, and they still know little of the virus. Days later, Gabe and Lian are sent to find evidence from a reported contaminated Nepal village. Gabe and Lian continue on the trail to and determine the next move of Erich Rhoemer, an international wanted terrorist. Soon enough Rhoemer and his men commenced a terrorist operation in the heart of Washington D.C, and makes demands to the government with the several viral bombs planted all over Washington D.C. as his trump card. In response, the Agency assigns Gabe and Lian to counter this terrorist effort, to find and deactivate the viral bombs and free the hostages in attempt to foil Rhoemer's act of terrorism. Gabe gets assistance from the US Army Chemical and Biological Defence Command (CBDC) and Lian who will stay in frequent contact with Gabe throughout his missions.

miscellaneous

Air Taser

Fire Rate I
Damage IIIII
Clip Size N/A
Max Rounds Infinite

Using CO2 cartridges, this weapon fires a probe that lodges one inch deep in the victim's body. Then a charge of 500,000 volts is passed along a wire connecting the weapon to the probe. This charge can be sustained indefinitely. Hold the square button to ignite and continue to hold it down until your victim catches fire.

Nerve Gas Grenade

Fire Rate I
Damage IIIII
Clip Size N/A
Max Rounds 10

Primarily used as a stealth weapon against multiple targets, this grenade releases trace amounts of Soman nerve agent into the air. The gas quickly dissipates, but not before rendering victims unconscious. If no antidote is administered, death follows within 15 minutes. The gas dissipates swifly for fast entry into the area. This will stun an agent for a brief moment if walked into.
